RESUMO

OBJECTIVE: The aim of this study was to compare the outcomes and complications of selected patients treated with endovenous laser ablation (EVLA) or ambulatory phlebectomy for foot varicose veins. METHODS: From October 2016 to February 2022, selected patients undergoing EVLA (using 1470-nm with radial-slim or bare-tip fibers) or phlebectomy of foot varicose veins for cosmetic indications were analyzed, and the outcomes were compared. Patients were classified according to the Clinical, Etiologic, Anatomical, and Pathophysiological (CEAP) classification. Anatomic criteria provided the basis for the decision to perform EVLA or phlebectomy. Clinical and ultrasound assessments were performed on postoperative days 7, 30, and 90 for visualization of the sapheno-femoral and sapheno-popliteal junctions and the deep venous system. Disease severity was graded with the Venous Clinical Severity Score (VCSS), and quality of life was measured with the Aberdeen Varicose Vein Questionnaire (AVVQ) before and after treatment. Treatment outcomes were evaluated based on changes in VCSS and AVVQ scores. The groups were also compared for procedure-related complications. Data were statistically analyzed in SPSS v. 20.0 using the χ2, Student t test, Mann-Whitney test, Wilcoxon test, and analysis of variance. The results were presented as mean (standard deviation or median (interquartile range). RESULTS: The study included 270 feet of 171 patients. Mean patient age was 52.3 (standard deviation, 13.1) years, ranging from 21 to 84 years; 133 (77.8%) were women. Of 270 feet, 113 (41.9%) were treated with EVLA and 157 (58.1%) with phlebectomy. The median preoperative CEAP class was 2 (interquartile range, 2-3) in the phlebectomy and EVLA groups, with no statistically significant difference between the groups (P = .507). Dysesthesia was the most common complication in both groups. Only transient induration was significantly different between EVLA (7.1%) and phlebectomy (0.0%) (P = .001). The two approaches had an equal impact on quality of life and disease severity. CONCLUSIONS: Treatment complications were similar in phlebectomy and EVLA and to those previously described in the literature.

RESUMO

OBJECTIVE: Two-year follow-up results from a first-in-human study of patients implanted with the VenoValve are evaluated for supporting the long-term clinical safety and performance of the device. BACKGROUND: Chronic Venous Insufficiency (CVI) involves improper functioning of lower limb vein valves and inability of these valves to move blood back towards the heart. CVI symptoms include swelling, varicose veins, pain, and leg ulcers. Currently, there is no cure for this condition and treatment options are limited. This study provides 2-year outcomes for 8 patients who were implanted with the bioprosthetic VenoValve for treating severe CVI with deep venous reflux measured at the mid-popliteal vein. The 6-month and 1-year results were previously published. METHODS: Eleven patients with C5 & C6 CVI were implanted with VenoValve into the midthigh femoral vein and followed for 2 years. Assessed clinical outcomes include device-related adverse events, reflux time, disease severity, and pain scores. RESULTS: All 11 implant procedures were successful. Two-year follow-up data was obtained for 8 subjects: 1 patient died of non-device related causes, 1 was lost to follow-up, and 1 refused to follow-up due to the COVID-19 pandemic. No device-related adverse events occurred between the first and second years of follow-up. Reported 2-year clinical performance outcomes included significant decreases in mean reflux times of the mid-popliteal vein (61%), and significant improvements in mean scores for disease severity rVCSS (56%) and VAS pain (87%). CONCLUSIONS: Results from this study support long-term safety and effectiveness of the VenoValve for improving CVI severity by reducing reflux and thereby venous pressures in the lower extremities. With limited treatments for valvular incompetence involved in severe, deep venous CVI, the device may be considered as a novel therapy. A pivotal trial in the United States is currently being conducted to assess the device in a larger number of patients.

RESUMO

OBJECTIVE: Minimally invasive techniques have been increasingly used to treat pathologic perforator veins (PVs). The goal of the present study was to summarize the current literature and determine the outcomes of treating PVs with or without the great saphenous vein/small saphenous vein using endovenous laser ablation (EVLA), radiofrequency ablation (RFA), and ultrasound-guided sclerotherapy (USGS). METHODS: A systematic review of the literature on the percutaneous treatment of PVs (35 studies) was conducted in accordance with the PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines. Studies reported up to March 2020 were included. The incidence of several end points at different follow-up periods were calculated according to the availability of data within 3 to 12 months after the index procedure. RESULTS: Of the 35 studies, 15 (n = 1677) had reported on EVLA with or without sclerotherapy and/or microphlebectomy, 12 (n = 1477) had investigated the outcomes of RFA ablation with/without sclerotherapy, and 8 (n = 331) had investigated USGS alone. All techniques were safe in terms of periprocedural adverse events, with only a few complications occurring in each group. Immediate procedural success (within 30 days) was 95% in the EVLA group, 91% in the RFS group, and 58% to 70% in the USGS group. At 12 months of follow-up, the occlusion rates were 89%, 77%, and 83% in the EVLA, RFA, and USGS groups, respectively. The 12-month pooled estimate of ulcer healing between the EVLA and RFA groups was similar, although no direct comparisons were performed. CONCLUSIONS: Treatment of PVs with percutaneous techniques, such as EVLA, RFA, and USGS, is safe and associated with high technical success. EVLA and RFA exhibited the most favorable outcomes. Additional research is needed to validate these results, which were based on the limited level of evidence available to better determine the most optimal treatment approach for lower limb pathologic PVs.

RESUMO

OBJECTIVE: Lower extremity varicose veins have a high prevalence and can be associated with significant morbidity in their more advanced presentations; overweight patients tend to present with more severe clinical symptoms and conventional surgical treatment remains challenging. Although the advent of ultrasound-guided foam sclerotherapy (UGFS) increased the treatment options for these patients, the need for elastic compression after UGFS remains controversial. METHODS: Overweight patients with lower extremity varicose veins secondary to great saphenous vein reflux were treated with UGFS and then randomized to use or no use of a 3-week treatment of elastic compression stockings. Follow-up was performed by clinical evaluation and duplex ultrasound examination. The primary outcome measure was the absence of venous reflux in the great saphenous vein. RESULTS: One hundred thirty-five lower limbs were treated; 72 limbs were randomized to elastic compression and 63 limbs to the control group. There were no statistically significant differences in the number of procedures (P = .64) or the mean foam volume per procedure (P = .27) between groups. There was no difference in the reflux rate at either 3 weeks (26% vs 35%; P = .16) or 3 months (25% vs 21%; P = .85). Major complications were venous deep thrombosis (n = 2), neurologic event (n = 1), and ischemic ulceration (n = 1); the overall rate was 3% in both groups-2 of 62 in control patients and 2 of 69 in compression patients (P = .45). Venous diameter reduction was noted in both groups during treatment (P < .05) but with greater decrease in greater saphenous vein diameter in patients treated with compression. CONCLUSIONS: Elastic compression stockings for 3 consecutive weeks after UGFS in overweight patients did not decrease great saphenous vein reflux, need for repeat procedures, or the volume of foam injected. However, UGFS was associated with a greater and uniform reduction in saphenous vein diameter at all times after the procedure.

Pela avaliação das médias do Venous Clinical Severity Score (VCSS), houve diferença significativa antes e após o procedimento, com variação entre os grupos de 11,2 (p < 0,01). Conclusões: A escleroterapia por espuma guiada por ultrassom apresenta altas taxas de sucesso terapêutico, com índices de cicatrização de úlceras venosas elevados


Background: Ultrasound-guided polidocanol foam sclerotherapy is used to treat patients with venous ulcers. It is a minimally invasive procedure and is simple to perform, but it has high relapse rates. Objectives: To report short to medium term results in patients with venous ulcers treated using ultrasound-guided polidocanol foam sclerotherapy. Methods: A sample of 19 patients who had been treated with ultrasound-guided polidocanol foam sclerotherapy between January 2013 and December 2014 were followed-up. Time taken for ulcers to heal, improvement of clinical symptoms, recanalization of treated veins, and relapse of symptoms and of venous ulcers were analyzed. Results: Fifteen of the patients analyzed were female (78.9%) and four were male (21.1%). Overall mean age was 53 years. Follow-up times ranged from 448 days to 1,276 days (mean of 791 days). The mean duration of active ulcers was 53 months. At postoperative follow-up assessments, total recanalization was observed in 15.7%, partial recanalization in 21%, and occlusion in 47.3% of the veins that had been treated. There was only one case of ulcer relapse. Analysis of mean Venous Clinical Severity Scores (VCSS) revealed a significant difference from before to after the procedure, with a variation of 11.2 (p < 0.01). Conclusions: Ultrasound-guided foam sclerotherapy has high rates of therapeutic success and achieves high rates of venous ulcer healing

RESUMO

Há diferenças individuais no diâmetro da veia safena magna (VSM) em membros normais e doentes; sendo possível a identificação dessas alterações pelo ecocolor Doppler.ObjetivoAvaliar a associação da aplasia segmentar da VSM com a presença de varizes e/ou insuficiência da mesma em membros inferiores, usando o ecocolor Doppler em pacientes com clínica de doença venosa crônica (DVC).Métodos1.408 pacientes com queixas compatíveis de DVC de membros inferiores, sendo 1.286 do sexo feminino, com idade entre 17 e 85 anos, examinados com ecocolor Doppler. Foram incluídos aqueles com classificação CEAP clínica C0 a C4. Pela avaliação clínica, a amostra foi distribuída em grupo A, pacientes com varizes, e grupo B, aqueles sem varizes. O ecocolor Doppler determinou se havia aplasia da VSM pela análise do seu trajeto no compartimento safeno e presença de veias varicosas nos diferentes sítios. Para estatística, foram considerados os testes Qui-quadrado ou Exato de Fisher e uma análise de resíduos em tabelas, com nível de significância de 5%.ResultadosNo grupo A houve 479 (83,9%) de VSM insuficientes, 169 (38,2%) com aplasia e 71 (80,7%) com insuficiência e aplasia associadas. No grupo B, houve 92 (16,1%) de VSM insuficientes, 273 (61,8%) com aplasia e 17 (19,3%) com insuficiência e aplasia associadas.ConclusãoA aplasia segmentar da VSM ocorre mais em membros inferiores que não apresentam varizes e/ou insuficiência da mesma, mas considerando-se a presença da associação de aplasia e insuficiência, houve maior incidência no grupo de membros que apresentavam varizes.


There are individual differences in the diameter of the great saphenous vein (GSV) in both normal and non-functional limbs and it is possible to identify these differences using color Doppler ultrasonography.ObjectivesTo assess the association between segmental GSV aplasia and the presence of varicose veins and/or GSV insufficiency in lower limbs using color Doppler ultrasonography, in patients with chronic venous disease (CVD).MethodsA total of 1,408 patients with complaints compatible with CVD of lower limbs were examined using color Doppler ultrasonography. The age range of the sample was from 17 to 85 and 1,286 of the patients were female. People with clinical classifications (CEAP) ranging from C0 to C4 were included. On the basis of clinical examination, the sample was subdivided as follows: group A patients had varicose veins and group B patients were free from varicose veins. Color Doppler ultrasonography was used to determine whether there was GSV aplasia, by analysis of its route into the saphenous compartment, and the presence of varicose veins in different sites. Statistical analysis was conducted using the chi-square test or Fisher’s exact tests followed by an analysis of residuals in tables, with a 5% significance level.ResultsIn group A, there were 479 (83.9%) patients with GSV insufficiency, 169 (38.2%) with aplasia and 71 (80.7%) with both insufficiency and aplasia. In group B, there were 92 (16.1%) patients with GSV insufficiency, 273 (61.8%) with aplasia and 17 (19.3%) with both insufficiency and aplasia.ConclusionSegmental GSV aplasia was more common in lower limbs with no varicose veins and/or insufficiency, but there was a higher incidence of patients with both aplasia and insufficiency in the group with varicose veins.

RESUMO

Association between chronic venous disease and obesity has recently been studied, with indications that it may worsen in obese patients. The aim of study was to correlate clinical classes of chronic venous disease according to Clinical Etiology Anatomy Pathophysiology (CEAP) classification and body mass index, as well as to compare the severity of chronic venous disease in obese and nonobese patients. This retrospective cross-sectional prevalence study was conducted at the Maringá State University and Belczak Vascular Center along a period of 2 years, consisting of a random sample of 482 patients with complaints compatible with chronic venous disease. Data obtained from patient's files included gender, age, weight and height (for calculating body mass index), and clinical class (C) of chronic venous disease according to CEAP classification. Statistical analysis included Spearman's correlation coefficient, Chi-square test (for comparing frequencies), and Student's t-test (for comparing means). Significant positive correlation between body mass index and clinical classes was established for women (0.43), but not for men (0.07). Obesity (body mass index : ≥ : 30.0) was significantly more frequent in patients with chronic venous disease in clinical classes 3 (p < 0.001) and 4 (p = 0.002) and less frequent in patients with chronic venous disease in clinical class 1 (p < 0.001). This study evidenced significant correlation between body mass index and clinical classes of chronic venous disease in women, but not in men. It also corroborated the negative impact of obesity on the clinical severity of chronic venous disease.

RESUMO

Background: Venous insufficiency is a very prevalent disease. Some decades ago a group of patients was identified that had symptoms of venous insufficiency, but no visible anatomic abnormalities. Studies showed that this subset had reduced venous tone, and their condition became known as hypotonic phlebopathy. Objective: To investigate prevalence, age group and variations in body mass index (BMI) among patients with hypotonic phlebopathy. Methodology: A total of 1,960 limbs were examined in 1,017 patients who had been referred for complaints compatible with venous insufficiency. Patients with BMI ≥ 30 were defined as obese. The patients were examined using color Doppler ultrasonography to detect presence or absence of reflux in veins of the lower limbs and were then distributed into two groups as follows: patients with CEAP ≤ 1 and no reflux, diagnosed with hypotonic phlebopathy; or patients with CEAP ≥ 2 and reflux. Results: The study sample comprised 89.7% women and 10.3% men with a mean age of 44.9 years. Hypotonic phlebopathy was more common among the women (p = 0.0001). Obese women were more likely than women who were not obese to have venous symptom etiology involving trunk lesions (p = 0.0017). Among the men, obesity was unrelated to etiology of symptoms (p = 0.5991). Symptomology was more likely to be related to trunk vein damage among older age groups than among younger age groups (p-valor <0.0001). Conclusions: Hypotonic phlebopathy was very prevalent, particularly among young women who were not obese...


Contexto: A insuficiência venosa é uma doença muito prevalente. Há algumas décadas, evidenciou-se a existência de um grupo que, embora apresentasse sintomas de insuficiência venosa, não possuía alterações anatômicas visíveis. Estudos mostraram redução no tônus venoso nesses indivíduos, denominando-os portadores de flebopatia hipotônica. Objetivo: Estudar a prevalência, a faixa etária e as variações do índice de massa corporal (IMC) em pacientes portadores de flebopatia hipotônica. Metodologia: Foram examinados 1.960 membros de 1.017 pacientes, devido a queixas compatíveis com insuficiência venosa. Foram considerados obesos aqueles com IMC ≥ 30. Foram avaliados com ecocolor Doppler, para se detectar a presença ou não de refluxo em veias dos membros inferiores, sendo então distribuídos em dois grupos: aqueles com CEAP ≤ 1, além de excluído refluxo, os portadores de flebopatia hipotônica, e outros com CEAP ≥ 2 e com refluxo. Resultados: A amostra foi composta por 89,7% de mulheres e 10,3% de homens, com faixa etária média de 44,9 anos. A flebopatia hipotônica foi mais comum em mulheres (p-valor = 0,0001). Naquelas obesas, houve mais lesão troncular como etiologia dos sintomas venosos do que nas não obesas (p-valor = 0,0017). Dentre os homens, a presença de obesidade não influenciou na etiologia dos sintomas (p-valor = 0,5991). Nos grupos etários de idade mais avançada, a presença de sintomatologia teve como origem etiológica a lesão venosa troncular com mais frequência do que nas faixas etárias mais jovens (p-valor <0,0001). Conclusão: A flebopatia hipotônica se mostrou muito prevalente, principalmente em mulheres jovens não obesas...

RESUMO

A doença venosa crônica (DVC) é uma desordem complexa que compreende sinais e sintomas que variam das telangiectasias às úlceras ativas. A DVC é classificada de acordo com aspectos clínicos, etiológicos, anatômicos e fisiopatológicos (CEAP) em sete classes variando de C0 à C6. A principal causa da DVC é a hipertensão venosa que altera o fluxo venoso e, consequentemente, a força de cisalhamento que induz alterações fenotípicas nas células endoteliais que passam a expressar mediadores pró-inflamatórios e pró-trombóticos, que levam à adesão de leucócitos, ao aumento do estresse oxidativo, da permeabilidade vascular e do dano endotelial e ao remodelamento tecidual e vascular.Em virtude dos inúmeros mecanismos e da diversidade de moléculas envolvidas na patogênese e progressão da DVC, é essencial conhecer a interação entre elas e também saber quais são as moléculas (biomarcadores) que se correlacionam positivamente ou negativamente com a gravidade da doença. Foram avaliados os níveis de Interleucina-6 (IL-6), sL-selectina, sE-selectina, sP-selectina, molécula de adesão intercelular-1solúvel (sICAM-1), molécula de adesão das células vasculares-1 solúvel (sVCAM-1), ativador tecidual do plasminogênio (tPA), atividade do inibidor do ativador do plasminogênio-1 (PAI-1), trombomodulina solúvel (sTM), fator de von Willebrand (vWF), metaloproteinase de matriz (MMP)-2, MMP-3, MMP-9, inibidor tecidual das MMPs -1 (TIMP-1), angiopoietina-1 e -2, sTie-2 e s-Endoglina e fator de crescimento do endotélio vascular (VEGF) no sangue coletado da veia braquial de 173 mulheres com DVC primária divididas em grupos C2, C3, C4 e C4 menopausadas (C4m) e de 18 voluntárias saudáveis (grupo C0a). Foram também analisados os níveis urinários de ent-prostaglandina F2α nesses grupos. Não foram encontradas diferenças estatisticamente significativas com relação às concentrações sanguíneas e urinárias de sE-selectina, sP-selectina, sICAM-1, atividade de PAI-1, MMP-3, razão TIMP-1/MMP-3 ...


Chronic Venous Disease (CVD) is a complex disorder, which encompasses signs and symptoms that vary from telangiectasias to active ulcers. The CVD is classified according Clinical, Etiologic, Anatomical and Pathophysiological (CEAP) aspects into seven classes varying from C0 to C6. The main cause of CVD is venous hypertension, which alters venous flow and consequently, shear stress. Abnormal shear stress induces phenotypic changes in endothelial cells that start to express pro-inflammatory and pro-thrombotic mediators that lead to leukocyte adhesion, oxidative stress, increased vascular permeability and endothelial cell damage and tissue and vascular remodeling. Due to several mechanisms and the diversity of molecules involved in the pathogenesis and progression of CVD, is essential to know the interplay between them and which are the molecules (biomarkers) that correlate positively and negatively with the severity of the disease. We investigated the levels of interleukin-6 (IL-6), sL-selectin, sE-selectin, sP-selectin, soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular cell adhesion molecule-1 (sVCAM-1), tissue plasminogen activator (tPA), plasminogen activator inhibitor-1 (PAI-1) activity, soluble thrombomodulin (sTM), von Willebrand factor (vWf), matrix metalloproteinase (MMP)-2, MMP-3, MMP-9, tissue inhibitor of metaloproteinases-1 (TIMP-1), angiopoietin-1 and -2, sTie-2, s-Endoglin, vascular endothelial growth factor (VEGF) in the blood taken from the brachial vein of 173 patients with primary CVD divided into C2, C3, C4 and menopaused C4 (C4m) groups and 18 healthy volunteers (C0a group).We also investigated the urinary levels of ent-prostaglandin F2α in these groups. There was no statistically significant difference between groups with respect to blood or urinary levels of sE-selectin, sP-selectin, sICAM-1, PAI-1 activity, MMP-3, TIMP-1/MMP-3 ratio, angiopoietin-2, angiopoietin-1/angiopoietin-2 ratio, s-Endoglin ...
