RESUMEN

Background/Objective: The endovenous embolization of insufficient abdominal/pelvic veins is the preferred method of treatment. Also, it seems to be crucial in the treatment of lower limb vein insufficiency, particularly in recurrent disease. This study aimed to evaluate of pelvic vein embolization safety and its impact on the short-term outcome in the sequential treatment of venous disease. Methods: A retrospective analysis involved data from 506 female patients with venous disease involving abdominal and pelvic veins. All records were extracted from the medical database and included patient history, imaging reports as well as pre- and post-operative surveys. Results: Among the patients analyzed, 37.2% underwent some venous intervention in the past, with significant differences in symptom severity between groups. The embolization procedure revealed a high safety profile, with no serious complications. Pain during and after the procedure was generally low, with significantly lower pain scores in patients with recurrence. In patients who required left renal vein venoplasty a 1.7-fold increased risk of lumbar pain after embolization and venoplasty procedure was observed. Overall, 66.6% of patients reported improvement in pelvic symptoms and 72.1% experienced improvement in leg symptoms. The full sequential treatment protocol (abdominal, pelvic, and leg compartment) demonstrated superior outcomes in leg symptom improvement compared to embolization alone. Conclusions: Pelvic vein embolization is a safe and effective method of treatment, significantly improving both pelvic and leg symptoms, particularly in patients with a history of previous interventions in lower limb veins. Further studies are warranted to validate our findings and further refine treatment protocols.

RESUMEN

INTRODUCTION: Individuals with high body mass index (BMI) are more likely to have symptomatic LLVD than age matched populations with normal BMI. National priorities in venous disease set by the James Lind Alliance focus on improving access to healthcare and patient education. The aims of this study are to determine patient knowledge and potential burden of LLVD in a population of patients attending a UK, regional weight management service. METHODS: A postal questionnaire containing 12 questions relating to LLVD and obesity was distributed to the active list of patients under the weight management medical service at Dudley Group of Hospitals between May 2022-23. Respondents were provided with a stamped, addressed envelope to return the questionnaire. Ethical approval was granted by the Hampshire Research & Ethics Committee. RESULTS: Some 367 questionnaires were distributed to patients currently enrolled in specialist weight management services. 103 complete responses were received (28%), Most patients were between 50 and 70 years of age. 25% of patients already had a formal diagnosis of LLVD, with a further 84 (82%) reported signs or symptoms which may be related to LLVD. Almost half (49/103, 48%) had concerns over their skin quality with a similar proportion (25/103, 51%) having sought medical help. The majority (71/103, 69%) were unaware of the association between obesity and LLVD. Twelve participants had education regarding simple adjuncts designed to improve symptoms and/or prevent ulceration (emollients, dressings, stockings, or leg elevation). Four participants had previously undergone treatment for varicose veins. CONCLUSION: In a population of patients accessing weight management services, we have demonstrated that a quarter of patients have already received a diagnosis of LLVD, however there is for a greater undiagnosed burden of LLVD in part due to lack of patient and possibly clinician awareness.

RESUMEN

Chronic venous disease is a common condition causing pain, discomfort, and skin changes that effect quality of life and productivity. Various treatment modalities have been developed to manage retrograde venous blood flow and its associated complications, ranging from conservative therapy to more invasive techniques such as endothermal ablation and cyanoacrylate closure (CAC). Recently, CAC has gained popularity due to its faster recovery time and lower incidence of postprocedure discomfort and complications. The most commonly reported side effects include phlebitis, access site bruising or pain, and dermatitis. We present a case of phlebitis caused by Acinetobacter pittii following a CAC procedure using the VenaSeal device (Medtronic) in a patient with diabetes. The patient required surgical resection of the affected vein and prolonged antibiotic therapy. Bacterial contamination of the cyanoacrylate adhesive within a vein poses a significant treatment challenge with antibiotics alone due to biofilm production. Aggressive source control with removal of the adhesive-treated vein could be required for treatment of endovascular infections resulting from these common procedures.

RESUMEN

In the past decade, technologies to treat venous pathologies have increased dramatically, to the benefit of an often underserved and overlooked population of patients with venous disease. However, given the rapid release of various technologies, including venous-dedicated stents and thrombectomy devices across varied venous pathologies, evidence-based guidelines have been slow to develop. When discussing appropriateness of care, one needs to consider optimal patient selection, technical approach, medical management, and surveillance protocols, to name a few. All of which, in the venous space, are currently widely varied in practice. The future of deep venous work is limitless, but multicenter, randomized controlled trials are needed to optimally treat patients with venous disease.

RESUMEN

BACKGROUND: Increasing the levels of physical activity (PA) is widely recommended for people with chronic venous insufficiency (CVI). However, studies investigating the patterns of PA and adherence to PA guidelines using objective measures are lacking. OBJECTIVE: The primary aim was to examine the patterns of PA and adherence to PA guidelines among patients with CVI. A secondary aim was to identify whether adherence to PA recommendations differed according to patients' sociodemographic and clinical characteristics. METHODS: This cross-sectional study included 96 patients with CVI with Clinical-Etiology-Anatomy-Pathology (CEAP) C3 to C6 (69.1% women 59 ± 11 years; 51.5% C5-C6 on CEAP classification). Objective time spent in PA was measured by a triaxial accelerometer. To examine adherence to PA guidelines, patients were grouped as meeting (or) the recommendations if they had at least 150 min/week of moderate to vigorous PA. Sociodemographic and clinic characteristics were obtained by self-report. Binary logistic regression was employed to examine whether sociodemographic and clinical characteristics were associated with adherence to PA guidelines. T-tests were employed to compare PA levels at different intensities according to patients' age. RESULTS: Patients spent an average of 311.4 ± 91.5 min/week, 42.1 ± 28.0 min/week, and 19.8 ± 17.8 min/week in low-light PA, high-light PA, and moderate-to-vigorous PA, respectively. The proportion of patients meeting PA recommendations was 36.2%, and older patients had lower odds (OR = 0.94; 95%CI: 0.89 to 0.99). Additional analysis reinforced that by showing lower time in high-light PA (51.2 ± 30.0 min/day vs. 31.9 ± 21.8 min/day; p = .001) and moderate-to-vigorous PA (24.3 ± 15.8 min/day vs. 14.8 ± 18.8 min/day; p = .012) among older patients than their peers younger. CONCLUSION: Our findings showed that 36,2% of CVI patients met PA recommendations, with lower odds found among older patients. Public health interventions to enhance PA engagement among CVI patients should prioritize those who are older.

RESUMEN

Objectives: The current study evaluated the efficacy of iliac and IVC ultrasound alone for follow-up evaluation of iliac vein stents in patients with pelvic venous disorders or iliac occlusion from chronic deep vein thrombosis. Methods: A retrospective single site cohort study was conducted by evaluating the most recent 100 iliac vein and inferior vena cava ultrasounds in patients who had undergone iliac vein stenting. Inclusion criteria included a history of iliac vein stent placement. Exclusion criteria included patients under 18-years-old, duplicates of the same patient, and pregnancy at the time of ultrasound. The degree of visualization for color flow, gray scale, and phasicity were determined and classified into the following categories: complete, partial, or none. In addition, each chart was assessed for external compression, in-stent narrowing, and requirements for further imaging. Results: Of the 100 iliac vein and IVC ultrasounds assessed in this review, 99 of the ultrasounds were sufficient for evaluation during follow-up visits without requiring further investigation. Within this study cohort, the average follow-up time was 22 months. The average participant body mass index was 27.6. One iliac vein and IVC ultrasound was considered inadequate for follow-up evaluation and required further imaging. Conclusion: The use of iliac and IVC venous doppler ultrasound alone in the follow-up evaluation of iliac stent patency is effective and noninvasive and avoids unnecessary radiation exposure and cost.

RESUMEN

BACKGROUND: The comorbidity among vascular diseases has been widely reported, however, the contribution of shared genetic components remains ambiguous. METHODS: Based on genome-wide association study summary statistics, we employed statistical genetics methodologies to explore the shared genetic basis of eight vascular diseases: coronary artery disease, abdominal aortic aneurysm, ischemic stroke, peripheral artery disease, thoracic aortic aneurysm, phlebitis, varicose veins, and venous thromboembolism. We assessed global and local genetic correlations among these disorders by linkage disequilibrium score regression, high-definition likelihood, and local analysis of variant association. Cross-trait analyses conducted with CPASSOC identified pleiotropic variants and loci. Further, biological pathways at the multi-omics level were explored using multimarker analysis of genomic annotation, transcriptome-wide and proteome-wide association studies. Causal associations among the vascular diseases were evaluated by mendelian randomization and latent causal variable to assess vertical pleiotropic effects. RESULTS: We found significant global genetic associations in 18 pairs of vascular diseases. Additionally, we discovered 317 unique genomic regions where at least one pair of traits demonstrated significant correlation. Multi-trait association analysis identified 19,361 significant potential pleiotropic variants in 274 independent pleiotropic loci. Multi-trait colocalization analysis revealed 56 colocalized loci in specific disease sets. Gene-based analysis identified 700 potential pleiotropic genes, which were subsequently validated at both transcriptome and protein levels. Gene-set enrichment analysis supports the role of biological pathways such as vessel wall structure, coagulation and lipid transport in vascular disease. Additionally, 7 pairs of vascular diseases have a causal relationship. CONCLUSIONS: Our study indicates a shared genetic basis and the presence of common risk genes among vascular diseases. These findings offer novel insights into potential mechanisms underlying the association between vascular diseases, as well as provide guidance for interventions and treatments of multi-vascular conditions.

RESUMEN

OBJECTIVE: Patients with chronic venous disease (CVD) can present with different underlying hemodynamic abnormalities affecting the deep, superficial, and perforator veins. This review explores the relationship between reflux patterns, extent of venous reflux, and clinical manifestations of CVD. METHODS: The Medline and EMBASE databases were searched systematically from 1946 to April 1, 2024. References of shortlisted papers were searched for relevant articles. Studies were included if they were in English language, included participants ≥16 years of age, documented reflux patterns in two or more of the following: deep, superficial, and/or perforator systems, and related patterns to presentation or severity. Exclusion criteria included patients with isolated deep venous thrombosis, post-thrombotic syndrome or stenotic or obstructive disease. RESULTS: We identified 18 studies (11,177 participants; range, 55-3016). Meta-analysis showed significant odds ratios (OR) for C4-6 disease being associated with deep reflux (OR, 2.41; 95% confidence interval [CI], 1.53-3.78) and perforator reflux (OR, 3.37; 95% CI, 2.16-5.27), but not superficial reflux (OR, 2.11; 95% CI, 0.87-5.14), vs C0-3 disease. Severe CVD (C4-6) was significantly associated with isolated deep, combined deep and superficial, and combined superficial and perforator reflux. The greatest risk of CVD progression (defined as de novo development of varicose veins and progression to greater CVD severity) was shown by two studies to be related to combined deep and superficial reflux. CONCLUSIONS: Although limited by the heterogenous nature of the studies, this review confirms that reflux pattern is a significant predictor of clinical class, and higher clinical, etiological, anatomical, and pathophysiological stages are associated with a higher prevalence of superficial, deep, and perforator reflux. Isolated deep and combined reflux also seem to be to predict the onset of leg ulceration. Future studies should relate reflux patterns to treatment outcomes, including recurrence risk. This work could help to inform health policies and management guidelines so that reflux patterns, in conjunction with other demographic and hemodynamic parameters, could be used to risk stratify patients and identify individuals who may benefit from earlier treatment.

RESUMEN

We present a case of embolization for post-angioplasty pseudoaneurysm of the internal mammary vein. A 62-year-old male presented to the emergency department with right upper extremity edema. One month prior, he underwent angioplasty of right cephalic, subclavian, and innominate veins for similar symptoms but felt they had worsened. Computed tomography with intravenous contrast revealed pseudoaneurysm of the right internal mammary vein, and the patient was taken emergently to the operating room where embolization was successfully performed. Central venous pseudoaneurysm is a rare complication of angioplasty and the unique considerations of the anatomic region necessitate discussion of the optimal treatment modality.

RESUMEN

Objectives: To depict the basics of percutaneous spermatic vein sclero-embolization through a right basilic vein access and to qualitatively assess the reduced discomfort and pain of this access compared to the femoral one through a VAS scale. Methods: From February 2019 to March 2020, 20 varicocele sclero-embolizations through a right basilic vein were performed and retrospectively evaluated. All patients were men with a median age of 24.5 years. Treatment technique is described, as well as mean radiation dose and procedural time, and complication rates. Results: Technical success was obtained in all patients. 1 access site complication requiring conversion to femoral access occurred. 100% of patients reported only a "mild" pain ranging from 1 to 3 on VAS scale, suggesting a comfortable access for this procedure. Conclusions: Basilic vein access determines easy left and right spermatic vein catheterization, rapid ambulation as well as easy monitoring of the access site for post-procedural evaluations.

RESUMEN

Sclerotherapy is the treatment of choice for telangiectasias and reticular veins. The most common side effects of this procedure are hyperpigmentation and matting, which are feared owing to their aesthetic damage and difficulty of treatment. Combined treatments with laser and hypertonic glucose sclerotherapy have been described with excellent results, but limited to treatment of veins of ≤2 mm in diameter. Cryo laser after foam sclerotherapy is a procedure to treat reticular veins in the lower extremities that utilizes first foam sclerotherapy with polidocanol than immediately followed by transdermal Nd:YAG 1064 laser treatment and we can treat veins ≤5 mm. This report presents a successful case of varicose vein treatment using combined transdermal laser and sclerotherapy with foam sclerotherapy with polidocanol to treat veins >2.5 mm in diameter.

RESUMEN

BACKGROUND: Micronized purified flavonoid fraction (MPFF) is a widely prescribed and extensively investigated venoactive drug (VAD). The standard dosage for MPFF is 500 mg administered twice daily. However, a new daily dose of 1000 mg has just been introduced. OBJECTIVE: This study investigated whether a daily dose of 1000 mg MPFF could be implemented and embraced by the public and still has the same therapeutic effects as conventional pharmaceuticals. METHODS: For this meta-analysis, we searched MEDLINE, Embase, Science of Web, Cochrane, and PubMed databases and forward and backward citations for studies published between database inception and March 2023. Three randomized controlled trials (RCTs) of comparison of different dosages of MPFF to evaluate whether there is a significant difference between them were included, without language or date restrictions. Due to the small sample size of the study included, we conducted a simple sensitivity test using a one-by-one exclusion method, and the results showed that the study did not affect the final consolidation conclusion. The quality of the evidence was assessed using the Cochrane risk-of-bias tool. RESULTS: Out of 232 studies, 99 were eligible and 39 RCTs had data, all with low to moderate bias. Overall, 1924 patients (experimental group: 967, control group: 957) in 3 RCTs met the criteria. There is no significant difference in patient compliance, efficacy, clinical adverse events, and quality of life scores between MPFF 1000 mg once daily and MPFF 500 mg twice daily (standardized mean difference [SMD]: 0.049 [0.048, 0.145], p=0.321, risk ratio [RR]: 0.981 [0.855, 1.125], p=0.904, and SMD: 0.063 [0.034, 0.160], p=0.203). INTERPRETATION: In symptomatic chronic venous disease patients, MPFF 1000 mg once daily and MPFF 500 mg twice daily improve patient compliance, lower limb discomfort, clinical adverse events, and quality of life scores similarly. Regular medical care should recommend MPFF 1000 mg daily more often. CLINICAL IMPACT: Micronized purified flavonoid fraction (MPFF) is a popular venoactive medication (VAD) in modern medicine.MPFF is effective in treating lower extremity venous problems.Currently, besides conventional 500 mg tablets, there exist alternative dosage forms such as solutions, chewable tablets, and other novel formulations for MPFF.The excessive frequency and amount of medication may have a negative impact on patient adherence.

RESUMEN

OBJECTIVE: Inflammation and endothelial dysfunction are important venous changes in patients with chronic venous disease (CVD). The use of the venoactive drugs remains an important treatment modality for patients with CVD, reducing the severity of the CVD-related symptoms and swelling but also reducing inflammation and protecting endothelial cells. In this research, the effects of the serum obtained from patients with CVD before and after sulodexide treatment were evaluated for in vivo and in vitro inflammatory markers and endothelial cell function. METHODS: Inflammatory markers (IL-6, matrix metalloproteinase-9 [MMP-9], vascular cell adhesion molecule-1 [VCAM-1], and von Willebrand factor [vWF]) from the incompetent great saphenous veins (GSVs) and from the systemic venous circulation were studied in 10 patients with CVD (C2s) before and after 2 months of sulodexide (2 × 500 lipasemic units/d) therapy. Serum obtained from the vein blood before and after sulodexide treatment was evaluated for in vitro cultured human umbilical vein endothelial cell function. RESULTS: The serum collected from lower leg incompetent GSVs had significantly elevated levels of VCAM-1 (+29%, P < .001) compared with the serum from the systemic circulation. Endothelial cells exposed to the serum from the incompetent lower leg veins of the untreated CVD patients demonstrated higher stimulated synthesis of MMP-9 (+17%, P < .01), as well as increased markers of senescence (prolongation of population doubling time, ß-galactosidase activity, and expression of p21 and p53 genes). CVD serum-induced senescent endothelial cells had a higher expression of genes regulating IL-6, MMP-9, VCAM-1, and vWF synthesis. The overall proinflammatory effect on endothelial cells by the serum collected from the incompetent GSVs was stronger as compared with the serum from the systemic circulation. Serum collected from the veins after sulodexide treatment caused lower levels of endothelial cell inflammatory markers as well as respective gene expression than serum obtained at the beginning of the study (before sulodexide treatment). Sulodexide application also reduced the inflammatory secretory activity of the senescent endothelial cells. Sulodexide treatment resulted in the decrease of the majority of the studied inflammatory parameters in both lower limb incompetent vein and systemic blood. CONCLUSIONS: In patients with CVD, there are significant differences between circulating inflammatory markers analyzed from the lower leg incompetent GSV segments compared with the systemic circulation, indicating a higher inflammatory condition in CVD. Treatment with sulodexide reduces the proinflammatory and endothelial cell activation properties of the serum from patients with CVD. CLINICAL RELEVANCE: The study documented the significant proinflammatory human vascular endothelial cell activation when exposed to the serum collected from the varicose veins as compared with the serum from the systemic circulation in patients with chronic venous disease (CVD). The inflammatory marker expression, endothelial dysfunction, and endothelial cell senescence transformation can be successfully controlled and downregulated by patients' exposure to the glycosaminoglycan (sulodexide) treatment. Further studies are needed to confirm if glycosaminoglycan application can prevent further CVD clinical progression due to potential CVD-related pathological processes' modulation and their downregulation.

RESUMEN

Substantial advances occurred in phlebological practice in the last two decades. With the use of modern diagnostic equipment, the patients' venous hemodynamics can be examined in detail in everyday practice. Application of venous segments for arterial bypasses motivated studies on the effect of hemodynamic load on the venous wall. New animal models have been developed to study hemodynamic effects on the venous system. In vivo and in vitro studies revealed cellular phase transitions of venous endothelial, smooth muscle, and fibroblastic cells and changes in connective tissue composition, under hemodynamic load and at different locations of the chronically diseased venous system. This review is an attempt to integrate our knowledge from epidemiology, paleoanthropology and anthropology, clinical and experimental hemodynamic studies, histology, cell physiology, cell pathology, and molecular biology on the complex pathomechanism of this frequent disease. Our conclusion is that the disease is initiated by limited genetic adaptation of mankind not to bipedalism but to bipedalism in the unmoving standing or sitting position. In the course of the disease several pathologic vicious circles emerge, sustained venous hypertension inducing cellular phase transitions, chronic wall inflammation, apoptosis of cells, pathologic dilation, and valvular damage which, in turn, further aggravate the venous hypertension.

RESUMEN

Introduction: Chronic venous disease (CVD) constitutes a frequently underdiagnosed pathological condition that progressively diminishes patients' quality of life and imposes an escalating strain on healthcare resources. This study aims to comprehensively investigate the epidemiological landscape of varicose vein disease, examining age group distributions, gender patterns, residence influences, marital status correlations, weight considerations, educational impacts, and various aspects related to varicose veins. Material and methods: This was a single-centre retrospective analysis, in Albania from May 2018 to September 2023. Data were collected retrospectively through hospital records. Data collection involved administering a structured questionnaire to study participants, categorically organised into three sections. The first section focused on collecting demographic information, the second section involved self-perception of identifying risk factors associated with varicose veins, and the final section included inquiries about the history of variceal surgery. Results: The CEAP classification distribution in our cohort revealed a predominant presence of C2 (varicose veins) in 53.3% of patients, followed by C3 (oedema) at 29.2%, and C4 (changes in skin and subcutaneous tissue secondary to CVD) at 10.5%, whereas C5 (healed venous ulcer) and C6 (active venous ulcer) were less frequent. Based on the body mass index (BMI) scale, data from patients indicated that 9.7% were in the category of underweight, 54.8% had a normal BMI, and 35.5% were categorised as overweight. Conclusions: The study's thorough exploration of patient perspectives, risk factors, and treatment choices contributes to a holistic understanding of varicose vein management, emphasising the importance of personalised approaches that account for demographic variations and individual beliefs.

RESUMEN

Varicose veins (VVs) are the most common manifestation of chronic venous disease (CVD) and appear as abnormally enlarged and tortuous superficial veins. VVs result from functional abnormalities in the venous circulation of the lower extremities, such as venous hypertension, venous valve incompetence, and venous reflux. Previous studies indicate that enhanced angiogenesis and inflammation contribute to the progression and onset of VVs; however, dysregulations in signaling pathways associated with these processes in VVs patients are poorly understood. Therefore, in our study, we aimed to identify key regulators of angiogenesis and inflammation that are dysregulated in patients with VVs. Expression levels of 18 genes were analyzed in peripheral blood mononuclear cells (PBMC) using real-time PCR, as well as plasma levels of 6 proteins were investigated using ELISA. Higher levels of CCL5, PDGFA, VEGFC, TGF-alpha, TGF-beta 1, and VEGF-A, as well as lower levels of VEGFB and VEGF-C, were found to be statistically significant in the VV group compared to the control subjects without VVs. None of the analyzed factors was associated with the venous localization of the varicosities. The presented study identified dysregulations in key angiogenesis- and inflammation-related factors in PBMC and plasma from VVs patients, providing new insight into molecular mechanisms that could contribute to the development of VVs and point out promising candidates for circulatory biomarkers of this disease.

RESUMEN

OBJECTIVES: The aim of this study was to understand the prevalence of chronic venous disease (CVD) of lower limbs in young men at high-altitude in Xizang, and to provide prevention measures. METHODS: The convenient sampling method was used to conduct a questionnaire survey among males aged 18 to 40 above an altitude of 3000 meters in Xizang in April 2023. The contents of the questionnaire included basic information, symptoms of CVD of lower limbs, protection status and training needs. Multivariate logistic regression model was calculated to evaluate the risk factors for CVD. RESULTS: A total of 350 survey questionnaires were received, and 326 valid samples were collected. The prevalence of CVD of lower limbs (C1-C6) was 37.42% (95%CI: 32.17%-42.68%), the ratio of C0 to C5 were 62.58%, 27.30%, 3.07%, 4.60%, 2.15% and 0.31%, respectively, no one reached C6. The top three symptoms of CVD were lower limb fatigue (18.10%), heaviness (15.34%) and pain (13.19%). 46.01% of respondents were unaware of CVD, and 12.88% of respondents did not have any protective measures of CVD. Multivariate logistic regression showed that age (OR = 1.076, 95%CI: 1.018-1.137, p = .009), preference for spicy food (OR = 1.747, 95%CI: 1.083-2.818, p = .022), unbalanced diet (OR = 1.877, 95%CI: 1.049-3.358, p = .034) and physical exercise (OR 0.610, 95%CI: 0.377-0.986, p = .044) were the independent risk factors for CVD. CONCLUSIONS: This study provided data on the prevalence of CVD in young men at high-altitude and the risk factors for CVD. The findings of this study may facilitate the development of individualized clinical assessments and targeted prevention programs.
