RESUMEN
BACKGROUND: Frailty syndrome is prevalent among many patients experiencing intermittent claudication symptoms. Considering that components of the frailty syndrome can affect both physical and psychological functions, it is likely that barriers to physical activity are heightened in these individuals. AIM: To analyze the association between barriers to physical activity and frailty in patients with symptomatic peripheral artery disease (PAD). METHODS: This cross-sectional study included 216 patients with symptomatic PAD (64.8% men, 65.6±9.4 yrs.). Nine personal and 8 environmental barriers to physical activity were investigated through a questionnaire on barriers to practicing physical activity in patients with intermittent claudication. Frailty was defined according to Fried et al. (2001) criteria which included unintentional weight loss, exhaustion, low grip strength, slow walking speed, physical inactivity. Three or more criteria defined frail, one or 2 criteria defined pre-frail, and absence of criteria defined non-frail. Data are presented as median (interquartile range). RESULTS: Frail and pre-frail patients have more barriers than non-frail patients [frail: 11 (4); pre-frail: 10 (6); non-frail: 8 (7), p = 0.001]. Absence of a companion for physical activity, lack of knowledge and uncertainty about the benefits of physical activity, pain induced by walking and presence of obstacles that worsen leg pain were associated with frail and pre-frail status, independent of sex, age, ankle-brachial index, and total walking distance. CONCLUSION: Patients with PAD who are frail and pre-frail have more barriers to physical activity than non-frail patients. Therefore, specific interventions promoting PA are essential for these patients to improve their health outcomes.

BACKGROUND: The combination of rivaroxaban plus aspirin compared with aspirin alone reduces the risk of major adverse cardiovascular and limb events for high-risk patients with peripheral artery disease. It is unknown whether rivaroxaban plus aspirin improves intermittent claudication for adults with lower-risk peripheral arterial disease. METHODS: In this randomized, open-label, multicenter, 24-week clinical trial, we randomly assigned patients with peripheral artery disease and intermittent claudication to receive either 2.5 mg of rivaroxaban twice daily plus 100 mg of aspirin once daily or 100 mg of aspirin once daily. The primary outcome was a 24-week change in total walking distance, measured by the 6-minute walking test. The primary safety outcome was the incidence of major bleeding or clinically relevant nonmajor bleeding. RESULTS: Eighty-eight patients were randomly assigned to either rivaroxaban plus aspirin (n=46) or aspirin alone (n=42). The mean age was 67 years, and 54% were female. The total walking distance measured by 6-minute walk test improved by 89 ± 18 m (mean±standard error) in the rivaroxaban-plus-aspirin group versus 21 ± 16 m in the aspirin-alone group. This corresponded to an absolute difference of 68 ± 24 m (95% confidence interval [CI], 19 to 116 m; P=0.007) and a relative improvement over the aspirin-alone group of 327% (95% CI, 94 to 560%). No major bleeding events were observed in either group. CONCLUSIONS: In patients with peripheral artery disease and intermittent claudication, 2.5 mg of rivaroxaban twice daily plus 100 mg of aspirin daily improved the total walking distance by a 6-minute walking test compared with 100 mg of aspirin daily alone.

Background: There is a lack of randomized controlled trials focusing on orthopedic telemedicine (TM). The objective of this research was to compare the diagnostic accuracy and pattern of TM consultations of low-risk orthopedic patients performed by general practitioners (GPs) with those of face-to-face evaluations by orthopedists at an emergency department (ED). Methods: This randomized, single-center study was conducted between October 2021 and November 2022 on patients at an ED. Inclusion criteria were age >18 years, low back pain, extremity contusion, ankle sprain, or neck pain. Eligible patients were randomized 1:1 for TM consultations by generalist physicians with subsequent face-to-face orthopedic evaluations (TM-ED group) or face-to-face evaluations by orthopedic physicians (ED group). Primary outcomes were syndromic diagnosis, physical examination, and tests ordered. Secondary analysis included a satisfaction survey. Results: A total of 99 patients were enrolled; mean age was 41 ± 10.1 years, and 62.6% were female. The most common conditions were foot contusion (28.3%), ankle sprain (27.3%), hand contusion (19.2%), low back pain (19.2%), and neck pain (6.1%). Syndromic diagnosis showed no difference between groups (p = 0.231). In the TM-ED group (n = 51), self-examination demonstrated moderate to good agreement with face-to-face evaluations in several areas. Both groups showed similar tests practices. Patient satisfaction was higher in the TM-ED group across multiple measures. Conclusion: TM consultations for low-risk orthopedic patients by GPs are not inferior to face-to-face specialist evaluations at the ED. Virtual assessments are associated with higher patient satisfaction. Clinical Trial Identifier: NCT04981002.
RESUMEN
OBJECTIVES: The purpose of this investigation was to verify the association between mental health (MH) indicators with walking capacity in patients with PAD. METHODS: Two hundred and forty-six patients with PAD and claudication symptoms participated in this study. Physical function was assessed objectively with the 6-min walk test (6MWT) and subjectively using the Walking Impairment Questionnaire (WIQ). MH was assessed by the World Health Organization Quality of Life-Bref (WHOQOL-Bref) (six questions were selected - 1, 2, 10, 16, 19, and 26). Patients were divided into tertile groups according to their composite z-score for mental health (Low MH, Middle MH, and High MH). RESULTS: The High MH group presented higher scores (p < 0.05) for the WIQ (distance = 26.8 ± 25.6, speed = 25.4 ± 17.3, and stairs = 33.6 ± 27.5), claudication onset distance (161.6 ± 83.6 m), and total walking distance (352.9 ± 79.6 m) compared to Low MH (WIQ distance = 14.8 ± 16.2, 17.7 ± 13.0, and stairs = 22.7 ± 20.7). Additionally, the High MH group presented a longer claudication onset distance (115.5 ± 70.5 m), and total walking distance in 6MWT (306.6 ± 83.2 m), and higher scores in the total walking distance compared to Middle MH (309.5 ± 93.6 m) (p < 0.05). CONCLUSION: In patients with PAD, MH was positively associated with walking capacity. Based on these results, treatments that can improve mental health, through different mechanisms, can also positively influence the ability of these patients to walk.
RESUMEN
BACKGROUND: Patients with peripheral arterial disease have an increased risk of developing cardiovascular complications in the postoperative period of arterial surgeries known as Major Adverse Cardiac Events (MACE), which includes acute myocardial infarction, heart failure, malignant arrhythmias, and stroke. The preoperative evaluation aims to reduce mortality and the risk of MACE. However, there is no standardized approach to performing them. The aim of this study was to compare the preoperative evaluation conducted by general practitioners with those performed by cardiologists. METHODS: This is a retrospective analysis of medical records of patients who underwent elective arterial surgeries from January 2016 to December 2020 at a tertiary hospital in São Paulo, Brazil. The authors compared the preoperative evaluation of these patients according to the initial evaluator (general practitioners vs. cardiologists), assessing patients' clinical factors, mortality, postoperative MACE incidence, rate of requested non-invasive stratification tests, length of hospital stay, among others. RESULTS: 281 patients were evaluated: 169 assessed by cardiologists and 112 by general practitioners. Cardiologists requested more non-invasive stratification tests (40.8%) compared to general practitioners (9%) (p < 0.001), with no impact on mortality (8.8% versus 10.7%; p = 0.609) and postoperative MACE incidence (10.6% versus 6.2%; p = 0.209). The total length of hospital stay was longer in the cardiologist group (17.27 versus 11.79 days; p < 0.001). CONCLUSION: The increased request for exams didn't have a significant impact on mortality and postoperative MACE incidence, but prolonged the total length of hospital stay. Health managers should consider these findings and ensure appropriate utilization of human and financial resources.

The focus of this case report is to technically describe a noninvasive diagnostic evaluation of bow Hunter's syndrome using a dynamic computed tomography angiography protocol and discuss its advantages. In addition, we aimed to exemplify the quality of the study by presenting images of a 3D-printed model generated to help plan the surgical treatment for the patient. The dynamic computed tomography angiography protocol consisted of a first image acquisition with the patient in the anatomic position of the head and neck. This was followed by a second acquisition with the head and neck rotated to the side that triggered the symptoms, with technical parameters similar to the first acquisition. The acquired images were used to print a 3D model to better depict the findings for the surgical team. The dynamic computed tomography angiography protocol developed in this study helped visualize the vertebrobasilar arterial anatomy, detect vertebral artery stenosis produced by head and neck rotation, depict the structure responsible for artery stenosis (e.g., bony structure or membranes), and study possible complications of the disease (e.g., posterior cerebral circulation infarction). Additionally, the 3D-printed model better illustrated the findings of stenosis, aiding in surgical planning. In conclusion, dynamic computed tomography angiography for the evaluation of bow Hunter's syndrome is a feasible noninvasive technique that can be used as an alternative to traditional diagnostic methods.

PURPOSE: To describe a single-center experience with robotic-assisted endovascular treatment for transplant renal artery stenosis. MATERIALS AND METHODS: This is a single-center, retrospective, feasibility study of 4 consecutive cases of robotic-assisted endovascular surgery for transplant renal artery stenosis from October 2021 to August 2022. RESULTS: All lesions were identified, and stenting was performed with no complications. Conversion to manual control was not necessary. The mean fluoroscopy time was 25.25 min (range 12-60.9). A control Doppler ultrasound was routinely performed, demonstrating no residual lesions in all cases. There was no reintervention during the follow-up period. The operator learning curve was felt to be acceptable. CONCLUSION: Robotic-assisted endovascular treatment is a feasible technique for transplant renal artery stenosis.

PURPOSE: The six-minute walk test (6MWT) is extensively employed to evaluate gait impairment in patients with symptomatic peripheral artery disease (PAD) and has been associated with different health outcomes. However, various approaches exist for calculating and interpreting the six-minute test in order to address the needs of patients more effectively. Therefore, we investigated how these different approaches correlate with functional capacity and cardiovascular health in patients with symptomatic PAD. METHODS: In total, 227 PAD patients [65.2% men and 67 (13) y.o.] were included in this cross-sectional study. The 6MWT was performed along a 30-meter corridor and the distance was expressed in three ways: absolute (described as the meters walked during the test), relativized (based on the results of the 6MWT in healthy individuals), and DW (multiplying the body weight in kilograms by the absolute distance in the 6MWT). A functional capacity z-score was calculated using the results of the handgrip strength test, 4-meter walking test, and sit-and-stand test. A cardiovascular parameter z-score was calculated with data on brachial and central blood pressure, the low-frequency component/high-frequency component ratio, and carotid-femoral pulse wave velocity. RESULTS: The absolute (b = 0.30, 95%CI: 18-0.43, R² = 0.11, p < 0.001) and DW (b = 0.40, 95%CI: 27-0.53, R² = 0.17, p < 0.001) measures were related to functional capacity, independently of sex, age, and the ankle-arm index of the patients. Neither absolute nor DW were related to cardiovascular health. The relativized measure was not associated with either functional capacity or cardiovascular health. CONCLUSION: In patients with symptomatic PAD, absolute and DW measures are related to functional capacity, but not cardiovascular function.

OBJECTIVE: Through a retrospective analysis of 1,203 cases of referral from primary healthcare units to a specialized quaternary vascular surgical service, the findings of this study revealed a high proportion of inappropriate referrals, which may represent a substantial subutilization of this highly complex service. Consequently, in this study, we aimed to evaluate 1,203 cases of referral to a quaternary vascular surgical service, in São Paulo, Brazil, over a 6-year period, to assess the appropriate need for referral; in addition to the prevalence of surgical indications. METHODS: In this retrospective analysis, we reviewed the institutional records of participants referred from Basic Healthcare Units to a vascular surgical service inside the Brazilian Unified Health System, between May 2015 and December 2020. Demographic and clinical data were collected. The participants were stratified, as per the reason for referral to the vascular surgical service, previous imaging studies, and surgical treatment indications. Referral appropriateness and complementary examinations were evaluated for each disease cohort. Finally, the prevalence of cases requiring surgical treatment was defined as the outcome measure. RESULTS: Of the 1,203 referrals evaluated, venous disease was the main reason for referral (53%), followed by peripheral arterial disease (19.4%). A considerable proportion of participants had been referred without complementary imaging or after a long duration of undergoing an examination. Referrals were regarded as inappropriate in 517 (43%) cases. Of these, 32 cases (6.2%) had been referred to the vascular surgical service, as the incorrect specialty. The percentage of referred participants who ultimately underwent surgical treatment was 39.92%. Carotid (18%) and peripheral arterial diseases (18.4%) were correlated with a lower prevalence of surgical treatments. CONCLUSION: The rate of referral appropriateness to specialized vascular care from primary care settings was low. This may represent a subutilization of quaternary surgical services, with low rates of surgical treatment.

The aims of the current study were to analyze the association between the barriers to and changes in physical activity levels and sedentary behavior, as well as to examine whether these barriers change over time in patients with peripheral artery disease. In this longitudinal study, we assessed 72 patients (68% men; 65.7 ± 9.2 years). Physical activity was measured over a 7-day period using an accelerometer, and data were collected on time spent in sedentary activities, low-light physical activities, and moderate-to-vigorous physical activities. Personal and environmental barriers to physical activity were collected using yes or no questions. Assessments were repeated in the same patients after 27 months (95% confidence interval [26, 28] months). Most barriers remained stable in these patients; however, those who reported lack of money experienced an increase in sedentary behavior (ß = 392.9 [159.7] min/week, p = .02) and a decrease in low-light physical activity (ß = -372.4 [140.1] min/week, p = .02). These findings suggest that patients with symptomatic peripheral artery disease typically exhibit stable barriers over time, and individuals reporting lack of money demonstrated a decrease in low-light physical activity and an increase in sedentary behavior after 27 months.

BACKGROUND AND OBJECTIVE: Lower limb varicose veins are a prevalent disease associated with several available treatment options, including conventional surgery and polidocanol foam sclerotherapy. However, few studies have analyzed therapeutic modality outcomes based on Patient-Reported Outcome Measures (PROMs). This large sample-size study was designed to evaluate the outcomes of polidocanol foam sclerotherapy compared to conventional surgery based on an analysis of PROMs. METHODS: This was a prospective, observational, and qualitative study of 205 patients who underwent varicose vein treatment with either polidocanol foam sclerotherapy (57 patients, 90 legs) or conventional surgery (148 patients, 236 legs). Patients were preoperatively assessed and re-evaluated 30 days after the procedure using the Venous Disease Severity Score (VCSS) and specific venous disease quality-of-life questionnaires (VEINES-QoL/Sym). RESULTS: Both treatments significantly improved VCSS and VEINES results 30 days after the procedure (p < 0.05). However, surgery promoted greater improvements in VCSS (on average 4.02-points improvement, p < 0.001), VEINES-QoL (average 8-points improvement, p < 0.001), and VEINES-Sym (average 11.66 points improvement, p < 0.001) than did sclerotherapy. Postoperative pain and aesthetic concerns about the legs were the domains of the questionnaires in which the results varied the most between the treatment modalities, with worse results for sclerotherapy. CONCLUSION: Both polidocanol foam sclerotherapy and conventional surgery positively impact patients' quality of life after 30 days, but the improvement is more significant for patients who undergo conventional surgery.

OBJECTIVE: Robot-assisted endovascular surgery has emerged as a new alternative to interventional procedures, with its application expanding to peripheral and visceral approaches. The objective of this paper is to describe a robot-assisted endovascular treatment in splanchnic arteries. METHODS: A case report of an asymptomatic male patient with an incidental finding of a saccular aneurysm of the proper hepatic artery measuring 3.7 × 2.7 cm and distant 0.6 cm from the origin of the gastroduodenal artery. RESULTS: Using a robot-assisted endovascular technique (CorPath GRX platform - Siemens), 2 guidewires were advanced in parallel: the first one was placed inside the aneurysm sac, while the second one was placed in the proper hepatic artery distal to the aneurysm; through the first guidewire, a balloon was advanced, positioned distally to the aneurysm, and through the second one, a microcatheter was advanced. Embolization of the aneurysm was performed with the use of coils and Onyx. Control exam performed 120 days after embolization revealed treated aneurysm and preserved distal arterial flow. CONCLUSION: Using a robotic platform for navigation in splanchnic territory is safe and effective.
RESUMEN
INTRODUCTION: In peripheral artery disease (PAD) patients, the joint profile of low strength and cardiorespiratory fitness on movement behaviors, specifically physical activity levels and sedentary time, remains unclear. PURPOSE: To investigate the joint profiles between cardiorespiratory and neuromuscular fitness and daily physical activity among PAD patients. METHODS: Cross-sectional study in a sample of 155 PAD patients. We measured their physical activity level per week using accelerometers, assessed their muscle strength through a sit-to-stand test and cardiorespiratory fitness through a six-minute walk test. Patients were categorized into three groups: those with high strength and cardiorespiratory fitness (NC, n = 28), those with at least one component classified as low (1C, n = 88), and those with both components classified as low fitness (2C, n = 39). RESULTS: The patients in the 1C and 2C groups spent less time engaged in low-light and moderate activities compared to the NC group (low-light: NC: 2291 ± 680 minutes/week vs. 1C: 1826 ± 649 minutes/week vs. 2C: 1885 ± 651 minutes/week, p = .005; moderate: NC: 2617 ± 796 minutes/week vs. 1C: 2071 ± 767 minutes/week vs. 2C: 2092 ± 776 minutes/week, p = .005) and the patients in the 2C group spent less time engaged in vigorous activities compared to the NC and 1C groups (NC: 155 ± 148 minutes/week vs. 1C: 110 ± 110 minutes/week vs. 2C: 64 ± 70 minutes/week, p = .003). CONCLUSION: PAD patients with low strength and/or cardiorespiratory fitness are more likely to spend less time engaging in low-light and moderate physical activities and patients with low fitness in both components are more likely to spend less time engaging in vigorous physical activity.

OBJECTIVE: This study analyzed the impact of sex on self-reported health and lifestyle parameters in peripheral artery disease patients at two periods of the COVID-19 pandemic. METHODS: In this longitudinal study, 99 patients with peripheral artery disease (53 men and 46 women) were evaluated during two periods of the COVID-19 pandemic ( i.e ., at onset: May to August 2020, and on follow-up: May to August 2021). Patients were interviewed via telephone, and information regarding lifestyle and health parameters was obtained. RESULTS: At the onset of the COVID-19 pandemic, health and habit parameters were similar between women and men, with 63.0% and 45.3% indicating frequent fatigue, 73.9% and 84.9% reporting increased sitting time, and 23.9% and 39.6% practicing physical activity, respectively. At follow-up, difficulties in physical mobility (women: from 26.1% to 73.9%, p<0.001; men: from 39.6% to 71.7%, p=0.001) and the frequency of hospitalization for reasons other than COVID-19 increased similarly in women and men (women: from 4.3% to 21.7%, p=0.013; men: from 9.4% to 24.5%, p=0.038). The other parameters were similar between the periods. CONCLUSION: Self-reported physical mobility difficulties and hospitalization frequency increased in women and men with peripheral artery disease. BACKGROUND: ⪠Sitting time increased in 73.9% of women and 84.9% of men at the onset of the pandemic. BACKGROUND: ⪠Physical activity was practiced by 23.9% of women and 39.6% of men at the onset of the pandemic. BACKGROUND: ⪠The prevalence of both women and men reporting physical mobility difficulties increased at follow-up. BACKGROUND: ⪠Hospitalization rates for reasons unrelated to COVID-19 have increased in both women and. BACKGROUND: While women experience more consequences related to peripheral artery disease than men, such as worse functional capacity and higher morbidity, there was a similar increase in physical mobility difficulty and frequency of hospitalization for reasons other than COVID-19 one year after the onset of the pandemic.

OBJECTIVE: Understanding the causes of amputation is crucial for defining health policies that seek to avoid such an outcome, but only a few studies have investigated the epidemiology of patients submitted to amputations in developing countries. The objective of this study was to analyse all lower limb amputations performed in the public health system in Brazil over a 13 year period, evaluating trends in the number of cases, patient demographics, associated aetiologies, hospital length of stay, and in hospital mortality rate. METHODS: This was a retrospective, population based analysis of all lower limb amputations performed in the Brazilian public health system between 1 January 2008 and 31 December 2020. Using a public database, all types of amputations were selected, defining the number of procedures, their main aetiologies, anatomical level of limb loss, demographic data, regional distribution, and other variables of interest. RESULTS: A total of 633 455 amputations were performed between 2008 and 2020, mostly (55.6%) minor amputations, predominantly in males (67%). There was an upward trend in the number of amputations, determined mainly by the increase in major amputations (50.4% increase in the period). Elderly individuals have the highest rates of amputation. Diabetes mellitus (DM) is becoming the main primary diagnosis associated with amputations over the years. The highest in hospital mortality rate occurred after major amputations and was associated with peripheral arterial disease (PAD). CONCLUSION: Amputation rates in Brazil show an upward trend. DM is becoming the most frequent associated primary diagnosis, although PAD is the diagnosis most associated with major amputations and in hospital death.

BACKGROUND: During the COVID-19 pandemic, there was a dramatic increase in healthcare demand. Resources were redirected to care patients with COVID-19. Therefore, surgical treatments were affected, including those of vascular diseases. There are no studies evaluating the whole impact of the COVID-19 pandemic, considering all types of vascular procedures, both elective and urgent, in a large country. The aim of the present study was to analyze the impact on all types of vascular procedures performed in Brazilian public hospitals during the COVID-19 pandemic. METHODS: Cross-sectional population-based analysis of publicly available data referring to vascular procedures. Surgeries 2 years before the pandemic onset (2018-2019) and 2 years during pandemic (2020-2021) were included. RESULTS: We observed a total of 521,069 procedures. Decrease was observed in elective abdominal aortic aneurysm repairs both open surgery (P = 0.001) and endovascular surgery (P < 0.001), emergency open abdominal repairs (P = 0.005), elective thoracic aortic aneurysm repairs (P = 0.007), elective open peripheral aneurysm repairs (P = 0.038), carotid endarterectomies (P < 0.001) and angioplasties (P = 0.001), open revascularizations for peripheral arterial disease (P < 0.001), surgical treatment of chronic venous disease (P < 0.001) and sympathectomies for hyperhidrosis (P < 0.001). However, there was an increase of lower limb amputations (P = 0.027) and vena cava filter placements (P = 0.005). There was a reduction of almost US$17 million in financial investments. CONCLUSIONS: The reorganization of health systems led to a significant reduction in vascular procedures and decrease in financial investments. On the other hand, there was a significant increase in the number of lower limb amputations and vena cava filter placements.

BACKGROUND: To explore the influence of sociodemographic, behavioral, clinical, and anthropometric factors on the association between sex and functional capacity in patients with peripheral arterial disease. METHODS: A cross-sectional study was conducted with patients aged more than 45 years, diagnosed with peripheral artery disease (PAD), from 2 Brazilian hospitals. Data on sociodemographic characteristics, behavioral risk factors, clinical profile, and anthropometric measurements were collected. Functional capacity was assessed using the 6-min walk test and the Walking Impairment Questionnaire. Statistical analyses, including t-tests, chi-square tests, and logistic regression, were performed to assess the relationships between sex, functional capacity, and potential influencing factors. RESULTS: Among the 262 patients with PAD, 67 were women and 113 were men. Women exhibited lower absolute functional capacity and lower Walking Impairment Questionnaire scores compared to men, even after adjusting for potential confounders. However, relative functional capacity did not significantly differ between sexes after adjusting for variables. Pain-free walking distance was also lower in women compared to that in men, but this association lost significance after adjusting for sociodemographic factors. CONCLUSIONS: Women with PAD had lower absolute functional capacity compared to men, influenced by various factors such as sociodemographic, behavioral, clinical, and anthropometric factors. However, the relative functional capacity was similar between genders, being influenced only by behavioral factors, while for the distance walked until pain, the association was lost after adjustments for sociodemographic factors.
