RESUMEN
INTRODUCTION: Clinical guidelines recommend measurement of arterial (carotid and femoral) plaque burden by vascular ultrasound (VUS) as a risk modifier in individuals at low or moderate risk without known atherosclerotic cardiovascular disease (ASCVD). AIM: To evaluate the prevalence of carotid and femoral plaques by age and sex, the burden of subclinical atherosclerosis (SA), and its association with classic CVRF in subjects over 30 years of age without ASCVD. METHODS: We prospectively enrolled 5775 consecutive subjects referred for cardiovascular evaluation and determined the prevalence and burden of SA using 2D-VUS in carotid and femoral arteries. RESULTS: Sixty-one percent were men with a mean age of 51.3 (SD 10.6) years. Overall, plaque prevalence was 51% in carotid arteries, 39.3% in femoral arteries, 62.4% in carotid or femoral arteries, and 37.6% in neither. The prevalence of plaques and SA burden showed an increasing trend with age, being higher in men than in women and starting before the age of 40, both in the carotid and femoral sites. There was also an increasing prevalence of plaques according to the number of CVRF, and interestingly we found a high prevalence of plaques in subjects with 0 or 1 classic CVRF. CONCLUSIONS: We observed an increased prevalence and burden of carotid or femoral SA, higher in men, beginning before the fourth decade of life and increasing with age. Despite a significant association with classic CVRF, a significant number of subjects with low CVRF were diagnosed with SA.

BACKGROUND: Longitudinal associations of noninvasive 2-dimensional phase-contrast magnetic resonance imaging (2D-PC-MRI) velocity markers of the superficial femoral artery (SFA) were analyzed along with the characteristics of peripheral artery disease (PAD). We hypothesized that the 2-year differences in MRI-based measures of SFA velocity were associated with longitudinal changes in markers of PAD. METHODS: A total of 33 (11 diabetic, 22 nondiabetic) patients with PAD with baseline and 2-year follow-up MRI scans were included in this secondary analysis of the Effect of Lipid Modification on Peripheral Artery Disease after Endovascular Intervention Trial (ELIMIT). Electrocardiographically gated 2D-PC-MRI was performed at a proximal and a distal location of the distal SFA territory. SFA lumen, wall, and total vessel volumes and the normalized wall index (NWI) were analyzed. RESULTS: Baseline characteristics did not differ between diabetic and nondiabetic PAD patients. Maximum proximal and distal SFA velocity measures did not differ between baseline and 2 years (41.98 interquartile range (IQR) (23.58-72.6) cm/s vs. 40.31 IQR (26.69-61.29) cm/s; P = 0.30). Pooled analysis (N = 33) showed that the 24-month change in the NWI was inversely associated with the 24-month change in the proximal maximal SFA velocity (beta = -168.36, R2 = 0.150, P value = 0.03). The 24-month change of the maximum velocity differences between the proximal and distal SFA locations was inversely associated with the 24-month changes in peak walking distance (beta = -0.003, R2 = 0.360, P value = 0.011). CONCLUSION: The 2-year change of SFA plaque burden is inversely associated with the 2-year change of proximal peak SFA blood flow velocity. 2D-PC-MRI measured SFA velocity may be of interest in assessing PAD longitudinally.

BACKGROUND: Lower extremity atherosclerotic disease (LEAD) - also known as peripheral arterial disease - refers to the obstruction or narrowing of the large arteries of the lower limbs, most commonly caused by atheromatous plaque. Although in many cases of less severe disease patients can be asymptomatic, the major clinical manifestations of LEAD are intermittent claudication (IC) and critical limb ischaemia, also known as chronic limb-threatening ischaemia (CLTI). Revascularisation procedures including angioplasty, stenting, and bypass grafting may be required for those in whom the disease is severe or does not improve with non-surgical interventions. Maintaining vessel patency after revascularisation remains a challenge for vascular surgeons, since approximately 30% of vein grafts may present with restenosis in the first year due to myointimal hyperplasia. Restenosis can also occur after angioplasty and stenting. Restenosis and occlusions that occur more than two years after the procedure are generally related to progression of the atherosclerosis. Surveillance programmes with duplex ultrasound (DUS) scanning as part of postoperative care may facilitate early diagnosis of restenosis and help avoid amputation in people who have undergone revascularisation. OBJECTIVES: To assess the effects of DUS versus pulse palpation, arterial pressure index, angiography, or any combination of these, for surveillance of lower limb revascularisation in people with LEAD. SEARCH METHODS: The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase, CINAHL, and LILACS databases and World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registers to 1 February 2022. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and quasi-RCTs that compared DUS surveillance after lower limb revascularisation versus clinical surveillance characterised by medical examination with pulse palpation, with or without any other objective test, such as arterial pressure index measures (e.g. ankle-brachial index (ABI) or toe brachial index (TBI)). Our primary outcomes were limb salvage rate, vessel or graft secondary patency, and adverse events resulting from DUS surveillance. Secondary outcomes were all-cause mortality, functional walking ability assessed by walking distance, clinical severity scales, quality of life (QoL), re-intervention rates, and functional walking ability assessed by any validated walking impairment questionnaire. We presented the outcomes at two time points: two years or less after the original revascularisation (short term) and more than two years after the original revascularisation (long term). DATA COLLECTION AND ANALYSIS: We used standard Cochrane methodological procedures. We used the Cochrane RoB 1 tool to assess the risk of bias for RCTs and GRADE to assess the certainty of evidence. We performed meta-analysis when appropriate. MAIN RESULTS: We included three studies (1092 participants) that compared DUS plus pulse palpation and arterial pressure index (ABI or TBI) versus pulse palpation and arterial pressure index (ABI or TBI) for surveillance of lower limb revascularisation with bypass. One study each was conducted in Sweden and Finland, and the third study was conducted in the UK and Europe. The studies did not report adverse events resulting from DUS surveillance, functional walking ability, or clinical severity scales. No study assessed surveillance with DUS scanning after angioplasty or stenting, or both. We downgraded the certainty of evidence for risk of bias and imprecision. Duplex ultrasound plus pulse palpation and arterial pressure index (ABI or TBI) versus pulse palpation plus arterial pressure index (ABI or TBI) (short-term time point) In the short term, DUS surveillance may lead to little or no difference in limb salvage rate (risk ratio (RR) 0.84, 95% confidence interval (CI) 0.49 to 1.45; I² = 93%; 2 studies, 936 participants; low-certainty evidence) and vein graft secondary patency (RR 0.92, 95% CI 0.67 to 1.26; I² = 57%; 3 studies, 1092 participants; low-certainty evidence). DUS may lead to little or no difference in all-cause mortality (RR 1.11, 95% CI 0.70 to 1.74; 1 study, 594 participants; low-certainty evidence). There was no clear difference in QoL as assessed by the 36-item Short Form Health Survey (SF-36) physical score (mean difference (MD) 2 higher, 95% CI 2.59 lower to 6.59 higher; 1 study, 594 participants; low-certainty evidence); the SF-36 mental score (MD 3 higher, 95% CI 0.38 lower to 6.38 higher; 1 study, 594 participants; low-certainty evidence); or the EQ-5D utility score (MD 0.02 higher, 95% CI 0.03 lower to 0.07 higher; 1 study, 594 participants; low-certainty evidence). DUS may increase re-intervention rates when considered any therapeutic intervention (RR 1.38, 95% CI 1.05 to 1.81; 3 studies, 1092 participants; low-certainty evidence) or angiogram procedures (RR 1.53, 95% CI 1.12 to 2.08; 3 studies, 1092 participants; low-certainty evidence). Duplex ultrasound plus pulse palpation and arterial pressure index (ABI or TBI) versus pulse palpation plus arterial pressure index (ABI or TBI) (long-term time point) One study reported data after two years, but provided only vessel or graft secondary patency data. DUS may lead to little or no difference in vessel or graft secondary patency (RR 0.83, 95% CI 0.19 to 3.51; 1 study, 156 participants; low-certainty evidence). Other outcomes of interest were not reported at the long-term time point. AUTHORS' CONCLUSIONS: Based on low certainty evidence, we found no clear difference between DUS and standard surveillance in preventing limb amputation, morbidity, and mortality after lower limb revascularisation. We found no studies on DUS surveillance after angioplasty or stenting (or both), only studies on bypass grafting. High-quality RCTs should be performed to better inform the best medical surveillance of lower limb revascularisation that may reduce the burden of peripheral arterial disease.

BACKGROUND: Peripheral arterial disease (PAD) is a common and highly morbid disease. Although there have been recent advancements in the endovascular modalities to treat PAD, comparisons of these strategies, especially in the popliteal region, remain underinvestigated. The objective of this study was to compare midterm outcomes in patients with PAD undergoing treatment with both novel and SS compared with drug-coated balloon (DCB) angioplasty. METHODS: All patients at a multi-institution health system treated for PAD in the popliteal region from 2011 to 2019 were identified. Presenting features, operative details, and outcomes were included in the analysis. Patients who underwent popliteal revascularization with stents were compared with DCB. SS were compared separately with novel dedicated stents. Two-year primary patency was the primary outcome. RESULTS: We included 408 patients (72.7 ± 11.8 years old; 57.1% men) in the analysis. There were 221 (54.7%) patients who underwent popliteal stenting and 187 (45.3%) who underwent popliteal DCB. There were high rates of tissue loss in both groups (57.9% vs 50.8%; P = .14). Stented patients had longer lesions (112.4 ± 3.2 vs 100.2 ± 5.8 mm; P = .03) and higher rates of concomitant superficial femoral artery treatment (88.2% vs 39.6%; P < .01). Chronic total occlusions accounted for the majority of lesions treated (stent 62.4%, DCB 64.2%). Perioperative complications were similar between groups. Primary patency for the stented group was higher at two years than the DCB group (61.0% vs 46.1%; P = .03). When evaluating stented patients only, SS had higher 2-year patency than novel stents in the popliteal segment (69.6% vs 51.4%; P = .04). On multivariable analysis, stenosis, as opposed to chronic total occlusion, was associated with improved patency (hazard ratio, 0.49; 95% confidence interval, 0.25-0.96; P = .04), whereas novel stents were associated with worse primary patency (hazard ratio, 2.01; 95% confidence interval, 1.09-3.73; P = .03). CONCLUSIONS: In a population of patients with severe vascular disease, stents do not have inferior patency and limb salvage rates compared with DCB angioplasty when treating the popliteal region. For patients with advanced vascular disease, and especially tissue loss, stents and DCB are both beneficial when treating popliteal lesions.

BACKGROUND: In-stent restenosis remains a common and important complication after endovascular treatment of superficial femoral artery peripheral artery disease. It occurs in 14 to 35% of cases in 1 year and there is still no efficient treatment for this condition. Paclitaxel-coated balloons have shown promising results. OBJECTIVE: Investigate the 3 year results of superficial femoral artery in-stent restenosis treated with paclitaxel-coated balloon angioplasty, using the Lutonix™ 035 device. METHODS: We conducted a retrospective observational study with patients with symptomatic (Rutherford 2 to 5) superficial femoral artery in-stent restenosis, that were treated with paclitaxel-coated balloon angioplasty using the Lutonix™ 035 device, in a single center from January 2016 to December 2020. Duplex scan was used to follow the patients. Primary patency was obtained through Kaplan-Meier analysis. Mortality, and amputation rates were also evaluated. RESULTS: 105 patients were included. Two patients had technical failure and required an additional stent, and were thus excluded. 103 patients were analyzed. Primary patency was 91.26, 80.47, and 67.71%, respectively, in the first, second, and third year after the procedure. There were no deaths 30 days after the procedure. There were no major amputations during the 3 year follow-up. CONCLUSION: Paclitaxel-coated balloon angioplasty with the Lutonix™ 035 device was a safe and effective treatment to superficial femoral artery in-stent restenoses. The results were maintained along the 3 year follow-up.

OBJECTIVES: Peripheral artery disease is a worldwide epidemic that affects millions of patients, especially the elderly. It has a prevalence of 20% in individuals >80 years old. Although peripheral artery disease affects >20% of octogenarians, information about limb salvage rates in this patient population is limited. Therefore, this study aims to understand the impact of bypass surgery on limb salvage in patients aged >80 years with critical limb ischemia. METHODS: We conducted a retrospective analysis by querying the electronic medical records at a single institution from 2016 through 2022 to identify the population of interest and analyzed their outcomes after lower extremity bypass. The primary outcomes were limb salvage and primary patency, with hospital length of stay and 1-year mortality as secondary outcomes. RESULTS: We identified 137 patients who met the inclusion criteria. The lower extremity bypass population was divided into two cohorts: <80 years old (n = 111) with a mean age of 66 or ≥80 years old (n = 26) with a mean age of 84 years. The gender distribution was similar (P = .163). No significant difference was found in the two cohorts when it came to coronary artery disease, chronic kidney disease, or diabetes mellitus. However, when current and former smokers were grouped together, they were significantly more common in the younger cohort when compared with nonsmokers (P = .028). The primary end point of limb salvage was not significantly different between the two cohorts. Hospital length of stay was not significantly different between the two cohorts with 4.13 days vs 4.17 days in the younger vs octogenarian cohorts, respectively (P = .95). The 30-day all-cause readmissions were also not found to be significantly different between the two groups. The primary patency at 1 year was 75% and 77% (P = .16) for the <80-year-old and ≥80-year-old cohorts, respectively. Mortality was low in both cohorts, with two and three for the younger and octogenarian populations, respectively; thus, no analysis was performed. CONCLUSIONS: Our study shows that octogenarians who undergo the same preoperative risk assessment as younger populations have similar outcomes when it comes to primary patency, hospital length of stay, and limb salvage when comorbidities were considered. Further studies need to be done to determine the statistical impact on mortality in this population with a larger cohort.

BACKGROUND: Persistent sciatic artery (PSA) is a congenital malformation due to incomplete involution during the embryonic period. Its etiology is unknown, with an estimated incidence of 0.02 - 0.04% in the whole population and a mean age of 60-65 years. Its presentation can be bilateral. It is asymptomatic in most cases and is usually detected accidentally; however, some symptoms may appear, such as claudication, sciatic neuralgia, and pain in the affected limb. It can also manifest as an aneurysmal dilatation or thrombosis that can generate distal embolism with ischemia. CASE REPORT: In this case study, a patient in her 90s with a suspected peripheral arterial disease, which required an angiotomography of the lower limb, showing a superficial femoral artery running to the middle and distal third of the thigh and a vascular structure running in the sciatic neurovascular bundle corresponding to a persistent sciatic artery presenting atherosclerotic changes and extensive occlusion, was presented. The patient's treatment was clinical with dual antiplatelet therapy and prophylactic anticoagulation. This was due to comorbidities and age. Moreover, the PSA occlusion was not critical and did not significantly impact the patient's quality of life. CONCLUSION: Most patients with this anatomical variant are asymptomatic all their lives, but some of them may present symptoms with serious consequences. It is important to suspect it by clinical presentation and perform diagnostic confirmation by angiotomography. Treatment has yielded excellent results with endovascular techniques. Certain patients only require conservative treatment with anticoagulants and antiplatelet agents.

BACKGROUND: Patients with peripheral artery disease (PAD) requiring lower extremity revascularization (LER) have a high risk of adverse limb and cardiovascular events. The results from the VOYAGER PAD (efficacy and safety of rivaroxaban in reducing the risk of major thrombotic vascular events in subjects with symptomatic peripheral artery disease undergoing peripheral revascularization procedures of the lower extremities) trial have demonstrated that rivaroxaban significantly reduced this risk with an overall favorable net benefit for patients undergoing surgical revascularization. However, the efficacy and safety for those treated by surgical bypass, including stratification by bypass conduit (venous or prosthetic), has not yet been described. METHODS: In the VOYAGER PAD trial, patients who had undergone surgical and endovascular infrainguinal LER to treat PAD were randomized to rivaroxaban 2.5 mg twice daily or placebo on top of background antiplatelet therapy (aspirin 100 mg to be used in all and clopidogrel in some at the treating physician's discretion) and followed up for a median of 28 months. The primary end point was a composite of acute limb ischemia, major amputation of vascular etiology, myocardial infarction, ischemic stroke, and cardiovascular death. The principal safety outcome was major bleeding using the TIMI (thrombolysis in myocardial infarction) scale. The index procedure details, including conduit type (venous vs prosthetic), were collected at baseline. RESULTS: Among 6564 randomized patients, 2185 (33%) had undergone surgical LER. Of these 2185 patients, surgical bypass had been performed for 1448 (66%), using a prosthetic conduit for 773 patients (53%) and venous conduit for 646 patients (45%). Adjusting for the baseline differences and anatomic factors, the risk of unplanned limb revascularization in the placebo arm was 2.5-fold higher for those receiving a prosthetic conduit vs a venous conduit (adjusted hazard ratio [HR], 2.53; 95% confidence interval [CI], 1.65-3.90; P < .001), and the risk of acute limb ischemia was three times greater (adjusted HR, 3.07; 95% CI, 1.84-5.11; P < .001). The use of rivaroxaban reduced the primary outcome for the patients treated with bypass surgery (HR, 0.78; 95% CI, 0.62-0.98), with consistent benefits for those receiving venous (HR, 0.66; 95% CI, 0.49-0.96) and prosthetic (HR, 0.87; 95% CI, 0.66-1.15) conduits (Pinteraction = .254). In the overall trial, major bleeding using the TIMI scale was increased with rivaroxaban. However, the numbers for those treated with bypass surgery were low (five with rivaroxaban vs nine with placebo; HR, 0.55; 95% CI, 0.18-1.65) and not powered to show statistical significance. CONCLUSIONS: Surgical bypass with a prosthetic conduit was associated with significantly higher rates of major adverse limb events relative to venous conduits even after adjustment for patient and anatomic characteristics. Adding rivaroxaban 2.5 mg twice daily to aspirin or dual antiplatelet therapy significantly reduced this risk, with an increase in the bleeding risk, but had a favorable benefit risk for patients treated with bypass surgery, regardless of conduit type. Rivaroxaban should be considered after lower extremity bypass for symptomatic PAD to reduce ischemic complications of the heart, limb, and brain.

BACKGROUND: Strategies for the most effective treatment for peripheral arterial disease (PAD) remain controversial among clinicians. Several trials have shown improved primary patency of femoropopliteal interventions with the utilization of paclitaxel-coated balloons or stents compared to conventional balloons or stents. However, a 2018 meta-analysis suggested an increased mortality risk for patients receiving drug-coated balloons or stents (DCBS), resulting in an international pause in the use of DCBS. A 2021 meta-analysis by the same group suggested an increased risk of major amputation following DCBS use in peripheral arterial revascularization procedures. Here we report our long-term institutional outcomes comparing uncoated devices to DCBS. METHODS: A retrospective review of all patients who underwent peripheral arterial angioplasty, stenting, atherectomy, or a combination between 2011 and 2020 within a regional healthcare system was performed. Univariate, multivariate, and survival analyses were performed using standard statistical methods to assess the primary end points of overall survival, 5-year survival, and amputation-free survival. RESULTS: A total of 2,717 patients were identified, of whom 1,965 were treated with conventional uncoated devices and 752 were treated with DCBS. A univariate analysis showed that patients treated with non-DCBS had higher rates of overall mortality, major amputations, and mortality at 1, 3, and 5 years. A multivariable analysis demonstrated that the use of conventional devices, age, diabetes, chronic kidney disease, myocardial infarction, transient ischemic attack, warfarin use, and atrial fibrillation all significantly increased the risk of 5-year mortality, overall mortality, and combined mortality and/or amputation. CONCLUSIONS: DCBS are not associated with increased mortality or worse amputation-free survival in this real-world cohort of patients treated for PAD. Our data suggest that mortality is more closely linked with pre-existing patient comorbidities rather than device selection at the time of revascularization.

Introduction: Peripheral arterial disease in diabetic atherosclerotic patients is usually underdiagnosed, since the majority of the affected population is asymptomatic. Objective: Correlate the clinical and ultrasonographic signs of peripheral arterial disease of the lower limbs in diabetic atherosclerotic patients. Methods: A descriptive and prospective study was conducted in a random sample of 209 diabetic patients with peripheral arterial disease, according to the Leriche-Fontaine classification. These underwent Doppler ultrasound. The statistical study was performed by applying the Kappa coefficient. Results: Peripheral arterial disease predominated in males aged 60 years and over. In 26.32 percent of the left lower limb in the posterior tibial, the absence of pulse was confirmed. According to the clinical picture, by Leriche-Fontaine classification, the highest incidence was found in stage IIb with 33.97 percent, followed by stage II with 20.54 percent; and by ultrasound classification there was a significant reduction in diameter in the left leg in distal arteries, with a Kappa coefficient of 0.927. Conclusions: There was a strong clinical ultrasound correlation regarding the degree of stenosis in peripheral arterial disease of the diabetic patients studied(AU)

OBJECTIVE: Single segment great saphenous vein (GSV) is the preferred conduit in infrainguinal bypass. Alternative autologous conduits (AAC) and nonautologous biologic conduits (NABC) are thought to be a better alternative to traditional prosthetic conduits (PC) in the absence of GSV. In this study we analyzed the outcomes of these alternative conduits in lower extremity bypasses (LEB) in patients with chronic limb-threatening ischemia. METHODS: The Vascular Quality Initiative LEB database from 2003 to 2020 was queried for this study, to identify LEB in patients with chronic limb-threatening ischemia. Primary outcomes were graft patency, major adverse limb events (MALE), and MALE-free survival at 1 year. Standard statistical methods were used as appropriate. RESULTS: We identified 22,671 LEB procedures (12,810 GSV, 6002 PC, 1907 AAC, and 1952 NABC). Compared with the GSV group, the other conduit patients were significantly older, had more comorbidities, had an increased rate of prior lower extremity interventions, had a higher rate of infrageniculate bypass targets, and were less ambulatory at baseline. The PC, AAC, and NABC groups had significantly higher rates of postoperative morbidity compared with the GSV group. The PC group had a higher 30-day mortality compared with the GSV, AAC, and NABC groups (3% PC vs 2% GSV, 2% AAC, 2% NABC; P = .049). Both PC and NABC had higher 1-year mortality compared with GSV and AAC (13% PC and 13% NABC vs 10% GSV, 10% AAC; P = .02). In an adjusted Cox regression model (stratified by infrageniculate target and adjusted for age, comorbidities, and prior vascular interventions) PC was not significantly different from GSV, but AAC (hazard ratio [HR], 1.41; 95% confidence interval [CI], 1.19-1.67; P < .001) and NABC (HR, 1.9; 95% CI, 1.61-2.25; P < .001) were associated with an increased risk of loss of primary patency. A similar association with MALE was observed: both AAC (HR, 1.35; 95% CI, 1.15-1.58; P < .001) and NABC (HR, 1.8; 95% CI, 1.53-2.11; P < .001) were associated with an increased risk of MALE compared with GSV; PC was not significantly different from GSV. CONCLUSIONS: In the absence of GSV, alternative conduits (autologous or nonautologous biologic) do not confer a benefit with regard to graft patency or MALE compared with PCs. Increased operating time or costs associated with the use of these conduits is not justified based on this study.

BACKGROUND: Patients undergoing lower extremity bypasses (LEB) are at a high risk of developing post-discharge complications requiring readmission. Health systems have developed several strategies to mitigate this risk. One such measure is developing comprehensive Transitional Care Program (TCP), which includes phone calls to patients after being discharged from the hospital. Our study aimed to assess short-term readmission, mortality, and amputation rates of patients who participated in TCP by completing at least one post-discharge follow-up phone call after undergoing LEB for revascularization of peripheral arterial disease (PAD). METHODS: A retrospective review was completed for patients who underwent LEB surgery between January 2010 and January 2020 to treat PAD at Penn State Hershey Medical Center. Immediate discharge follow-up was done via telephone calls using a standardized script. Patients were then divided into two groups, those who did not have a successful follow-up call (Group I) and those who had at least one successful follow-up call within seven days after discharge (Group II). Univariate analysis was used to compare preoperative demographics, intraoperative variables, and postoperative outcomes. The probability of readmission and risk factors contributing to it were computed using multiple stepwise forward regression analyses. Epidemiological analysis was done to evaluate the risk of readmission in the group receiving post-discharge follow-up calls. RESULTS: A total of 457 patients underwent LEB from 2010 to 2020 and qualified for inclusion in the study. Among these patients, 126 (27.6%) did not have a successful post-discharge follow-up call (Group I), whereas, 331 (72.4%) patients did complete a successful call (Group II). The mean age of patients was 66.7 years. There were no significant differences in preoperative baseline patient characteristics or intraoperative factors. Patients who completed a successful call had lower readmission rates within thirty days of the operation (8.8 vs. 17.5%, P = 0.008), and this was sustained in multivariate analysis (adjusted odds ratio AOR: 0.18, [confidence interval CI: 0.05-0.66], P = 0.009). However, no differences were observed for thirty-day mortality (Group-I: 3.2% versus Group-II: 1.2%, P = 0.152) or amputation (Group-I: 9.6% versus Group II 5.9%, P = 0.162). Among those who had a successful call, patients with a history of smoking (AOR: 4.05 [CI: 1.21, 17.12] P = 0.025), diabetes mellitus (AOR: 3.42 [CI: 1.35, 8.7] P = 0.01) and myocardial infarction (AOR: 7.15 [CI: 1.76, 20.1] P = 0.006) had a much higher chances of readmission. Risk analysis using epidemiological methods showed that by receiving a call, the risk of readmission could be dropped to half (RR: 0.50 [CI: 0.30, 0.84]), with an attributable risk reduction of -8.7% (CI: -15.9%, -1.4%). CONCLUSIONS: This single-institution retrospective study demonstrates the importance of immediate discharge follow-up phone calls in patients who undergo open lower extremity revascularization to reduce thirty-day readmissions. Our analysis showed patients who received immediate follow-up phone calls were less likely to be readmitted to the hospital. The development of reliable and efficient systems to enhance immediate discharge follow-up in vascular surgery patients is pivotal to improving quality of care, preventing readmissions, and reducing healthcare costs.

PURPOSE: The calcium score is a measure of vessel wall calcification and has clinical applications when studied in different vascular beds. The presence of vascular calcification in the arteries of the lower limbs is very common in patients with peripheral arterial disease; however, its relationship with the postoperative outcomes in patients undergoing lower limb revascularization is still poorly studied. The aim of this study is to evaluate association between the calcium score of lower limbs and the postoperative outcomes in patients with peripheral arterial disease undergoing revascularization procedures. METHODOLOGY: We retrospectively analyzed 88 lower limb revascularization procedures in 72 patients with critical limb ischemia who had enhanced computed tomography for preoperative evaluation. The calcium score was calculated, from the angiographic phase of preoperative computed tomography, in the segments of the aorta, iliac, femoropopliteal, and infrapopliteal. It was also calculated the calcium score of the operated limb, and the total calcium score using a standardized method. The outcomes evaluated were the occurrence of acute myocardial infarction, amputation, patency, technical success, and death from any cause. Patients were followed up through a 12 month period. RESULTS: Among the 88 procedures performed, 31 (43.1%) lesions were classified as Trans-Atlantic Inter-Society Consensus Document II D. There were 66 (75%) endovascular procedures, 16 (18.2%) open surgery, and 6 (6.8%) hybrid interventions. No statistically significant relationship was found between the calcium score of the segments (aorta, iliac, femoropopliteal, infrapopliteal, the operated limb, and total calcium score) and the outcomes of acute myocardial infarction, amputation, patency, and technical success in any of the periods analyzed. The calcium score of the operated limb was higher in patients who died within 30 days and 6 months (6571 vs 2590.6; p=0.026) and (5227.8 vs 2335.3; p=0.036). CONCLUSION: A standardized calcium score calculation method with the angiographic phase of the computed tomography is feasible and reproducible. Higher values of the calcifications of the operated limb are related to a greater chance of death in the postoperative period. The calcium score of the operated limb can be considered as a marker of clinical severity and prognosis in this group of patients.

BACKGROUND: Despite considerable morbid-mortality rates, common femoral endarterectomy is still considered the gold standard for atherosclerotic common femoral artery (CFA) disease. The aim of this study was to demonstrate computed tomography angiography based long-term patency after CFA stent placement and to analyze associated risk factors for restenosis. METHODS: A retrospective and observational study was carried out in consecutive patients treated with endovascular stent placement in CFA lesions. A clinical follow-up and imaging study was performed using MD-CTA to assess different degrees of in stent restenosis (ISR) and primary, assisted, and secondary patency rates. RESULTS: In a 5-year period, 35 extremities were treated in 33 patients with self-expandable nitinol stents. The technical success was 100% without complications related to the procedure. The mean follow-up (FU) was 32.2 months, and 8 limbs were lost. The degree of CFA stenosis was reduced from 79.69 ± 26.47% to 11.23 ± 24.53%. ISR < 20%, 20-70%, and ≥ 70% was evident in 15 (55.6%), 9 (33.3%), and 3 (11.1%) limbs, respectively. Estimated primary, assisted, and secondary patency was 79.5, 96.3, and 96.3%, respectively, after 24 months and 79.5, 96.3, and 96.3%, respectively after 60 months, with a freedom of clinical driven target lesion revascularisation rate of 87.8%. CONCLUSION: Endovascular treatment with self-expandable nitinol stents in CFA lesions had a high technical success rate and was related to few complications. A mild form of intimal hyperplasia was observed in a considerable number of cases. However, long-term patency was high; therefore, CFA stent placement might be a suitable therapeutic alternative in selected patients.

BACKGROUND: Symptomatic peripheral artery disease of the lower extremity rarely affects young adults and, when present, typically has a nonatherosclerotic etiology. Anatomical variants have manifested as symptomatic foot ischemia in four cases in the literature. We describe the case of a 17-year-old girl presenting with foot pain upon plantar flexion due to dynamic dorsalis pedis (DP) artery entrapment by fibrous bands and the extensor hallucis brevis (EHB) tendon. METHODS: The patient was a 17-year-old girl who presented with right foot pain upon plantar flexion, which resolved upon returning to the neutral position. The potential site of compression was identified on MRI where the DP artery ran deep to the EHB tendon near the first and second tarsometatarsal joints. On diagnostic arteriogram, there was notching of the dorsalis pedis over the talus bone. The dorsalis pedis Doppler signal was obliterated upon plantar flexion. A longitudinal incision was made over the artery in the area of compression. The flexor retinaculum was incised. Abnormal fibrous bands were identified, which were lysed anterior to the artery. The EHB tendon was released and transferred distally to the extensor hallucis longus tendon. RESULTS: A completion angiogram showed a persistently patent dorsalis pedis artery with plantar flexion. She was discharged one day postoperatively without issues. On follow-up, the patient was ambulatory with complete resolution of her pain. Arterial duplex demonstrated normal velocities through the dorsalis pedis in all positions. CONCLUSIONS: Symptomatic peripheral artery disease is a rare presentation in young adults and is usually due to nonatherosclerotic pathophysiology. We present a rare case of dorsalis pedis artery entrapment syndrome. Given the mechanical nature of obstruction, surgical correction was an effective treatment.

OBJECTIVE: The choice of intervention for treating suprainguinal arterial disease, open bypass vs endovascular intervention, is often tempered by patient age and comorbidities. In the present study, we compared the association of patient age with 1-year major adverse limb events (MALE)-free survival and reintervention-free survival (RFS) rates among patients undergoing intervention for suprainguinal arterial disease. METHODS: The Vascular Quality Initiative datasets for bypass and peripheral endovascular intervention (PVI; aorta and iliac only) were queried from 2010 to 2017. The patients were divided into two age groups: <60 and ≥60 years at the procedure. Age-stratified propensity matching of patients in bypass and endovascular procedure groups by demographic characteristics, comorbidities, and disease severity was used to identify the analysis samples. The 1-year MALE-free survival and RFS rates were compared using the log-rank test and Kaplan-Meier plots. Proportional hazard Cox regression was used to perform propensity score-adjusted comparisons of MALE-free survival and RFS. RESULTS: A total of 14,301 cases from the Vascular Quality Initiative datasets were included in the present study. Propensity matching led to 3062 cases in the ≥60-year group (1021 bypass; 2041 PVI) and 2548 cases in the <60-year group (1697 bypass; 851 PVI). In the crude comparison of the matched samples, the older patients undergoing bypass had had significantly greater in-hospital (4.6% vs 0.9%; P < .001) and 1-year (10.5% vs 7.5%; P = .005) mortality compared with those who had undergone endovascular intervention. The rates of MALE (7.5% vs 14.3%; P < .001) and reintervention (6.7% vs 12.7%; P < .001) or death were significantly higher for the younger group undergoing PVI than bypass at 1 year. However, the rates of MALE (12.9% vs 14.3%; P = .298) and reintervention (12.7% vs 12.9%; P = .881) or death for were similar both procedures for the older group. Both log-rank analyses and the adjusted propensity score analyses of MALE-free survival and RFS in the two age groups confirmed these findings. The adjusted comparison of outcomes using propensity score matching favored PVI at 1-year survival (hazard ratio, 1.4; 95% confidence interval, 1.1-1.9; P = .003) for the older group but was not different for the younger group (hazard ratio, 0.6; 95% confidence interval, 0.3-1.0; P = .054). CONCLUSIONS: Among the patients aged <60 years undergoing intervention for suprainguinal arterial disease, the choice of therapy should be open surgical intervention given the higher risk of reintervention and MALE with endovascular intervention. Endovascular intervention should be favored for patients aged ≥60 years because of reduced perioperative mortality.

Resumo Os aneurismas verdadeiros de artéria femoral profunda são extremamente raros, representando cerca de 0,5% do total dos aneurismas periféricos. Neste relato, descrevemos um paciente de 79 anos de idade, sexo masculino, com histórico de abordagem cirúrgica prévia convencional devido a aneurisma de aorta abdominal, que deu entrada no Serviço de Cirurgia Vascular do Hospital das Clínicas com quadro de claudicação intermitente de membros inferiores. Foi realizado eco-Doppler colorido arterial do membro inferior direito, que revelou doença arterial periférica femoro-poplítea e infrapatelar. A angiotomografia computadorizada identificou oclusão aortoilíaca e do enxerto bifurcado desde o segmento infrarrenal da aorta, além de aneurisma de artéria femoral profunda de 3,7 x 3,5 cm de diâmetro com 7 cm de extensão. Procedeu-se com a ressecção do aneurisma e revascularização da artéria femoral profunda por interposição de prótese de Dacron® e reimplante de artéria femoral superficial na prótese. Portanto, nos casos de aneurisma de artéria femoral profunda concomitante a doença arterial periférica, deve-se atentar para revascularização e perfusão adequada do membro inferior.
Abstract True deep femoral artery aneurysms are extremely rare, accounting for about 0.5% of all peripheral aneurysms. In this report, we describe a 79-year-old male patient with a history of prior abdominal aortic aneurysm surgery via a conventional approach who was admitted to the vascular surgery service at the Hospital das Clínicas with intermittent claudication of the lower limbs. Arterial color-Doppler ultrasonography of the right lower limb was performed, revealing peripheral arterial disease of the femoral--popliteal and infrapatellar segments. Computed tomography angiography identified aortoiliac and bifurcated graft occlusion from the infrarenal segment of the aorta, in addition to a deep femoral artery aneurysm with diameters of 3.7 cm x 3.5 cm and length of 7 cm. Resection of the aneurysm was followed by revascularization of the deep femoral artery by interposition of a Dacron® graft and reimplantation of the superficial femoral artery into the graft. In cases of deep femoral artery aneurysms with concomitant peripheral arterial disease, it is important to ensure revascularization and adequate perfusion of the lower limb.
