NCT05504070
A Post-Market, Multi-Center, Prospective, Interventional Study for Treatment of Chronic Venous Disease of the Great and Small Saphenous Veins and Incompetent Perforator Veins.
NCT07449728
Technically successful laser crossectomy will reduce the risk of reflux recurrence at the sapheno-femoral junction without increasing the risk of endovenous heat-induced thrombosis, which may positively impact the likelihood of ultrasound- or clinical-recurrence of varicose veins. Similar technical efficacy is expected for laser crossectomy at 1940 nm and 1470 nm. A possible advantage of the 1940 nm wavelength in terms of postoperative pain intensity and the risk of adverse events cannot be ruled out.
NCT06642051
The goal of this clinical trial is to learn if the Sonablate High Intensity Focused Ultrasound device can be safely used to treat patients with Chronic Venous Incompetence (CVI) including those with venous malformations of the periphery meaning legs, abdomen, chest or back. Examples of CVI are varicose veins, vascular congestion, venous ulcer, venous clusters, venous anomalies, mixed malformation, Klippel-Trenaunay Syndrome, CLOVES, Syndrome, Blue Rubber bleb Nevus Syndrome. HIFU is a non-invasive treatment as opposed to current treatment options which include incisions, needle penetration, wire insertions or catheter insertions.

NCT07233616
The prevalence of severe chronic venous insufficiency (CVI) is significant in the growing octogenarian population. While radiofrequency ablation (RFA) is a standard minimally invasive treatment, robust data on its outcomes and safety profiles specifically in patients aged 80 years and older remain scarce. This study aims to evaluate the risks and benefits of RFA in this specific, high-risk demographic.This prospective, single-arm, single-center cohort study will enroll 50 patients (initial target sample size) aged ≥80 years with CVI classified as CEAP C3 to C6 and with confirmed great or small saphenous vein reflux. All participants will undergo endovenous RFA under tumescent local anesthesia. The primary outcomes are: 1) the great/small saphenous vein occlusion rate at 6 months, assessed by duplex ultrasonography, and 2) the change in disease-specific quality of life from baseline to 6 months, measured by the Aberdeen Varicose Vein Questionnaire (AVVQ). Secondary outcomes include occlusion rates at 1 and 3 months; complication rates (e.g., deep vein thrombosis, skin burns, paresthesia) within 30 days; and changes in the Venous Clinical Severity Score (VCSS) and the 12-Item Short Form Health Survey (SF-12) at predefined intervals over 6 months.This study is designed to demonstrate a high technical success rate (occlusion rate \>95% at 6 months) and a statistically significant improvement in AVVQ and VCSS scores at 6 months post-procedure. The collected data will provide a detailed profile of complication rates, characterizing the safety of RFA in this very elderly cohort.This study will provide crucial, prospective evidence regarding the efficacy and safety of RFA for treating CVI in octogenarians. The findings are expected to guide clinical decision-making and inform treatment guidelines for this vulnerable and expanding patient population.
NCT05982405
The long-term effectiveness of inspiratory muscle training, which is known in the literature to help venous return by increasing the pump effect of the diaphragm muscle, remains unclear in individuals with chronic venous insufficiency. For this reason, in this study, it was aimed to investigate the long-term results of inspiratory muscle training in individuals with chronic venous insufficiency.
NCT06785805
This study aims to retrospectively examine the dataset obtained from a previously conducted study titled 'Inspiratory muscle training in individuals with chronic venous insufficiency: randomized controlled trial'. The previously conducted study was a study investigating the effectiveness of the application, and the current study aims to clarify the gap in the literature with the relationship between the data obtained from the patients at the beginning of that study. This study will be conducted by re-examining the initial data of another study from which data was collected before and conducting new analyses. H0: There is no relationship between disease severity, edema, pain, respiratory muscle strength, respiratory functions, aerobic capacity, lower extremity strength or quality of life in individuals with chronic venous insufficiency. H1: There is a relationship between disease severity, edema, pain, respiratory muscle strength, respiratory functions, aerobic capacity, lower extremity strength or quality of life in individuals with chronic venous insufficiency.
NCT05993650
There is insufficient evidence of inspiratory muscle training on venous function, clinical severity, symptoms and functional capacity and quality of life in CVI patients. Therefore, in the study, the investigators aimed to determine the effectiveness of inspiratory muscle training in individuals with chronic venous insufficiency.
NCT05383469
The aim of our study was to compare the effectiveness of active and passive practices in patients with CVI.
NCT04558957
The objective of the study is to collect clinical data of patients in whom Flebogrif® will have been used for mechanochemical ablation of incompetent veins in the follow-up period, as related to the safety, clinical effectiveness, properties and advantages of Flebogrif®. The proposed study is a prospective, multi-centre clinical trial assessing the safety, efficacy and quality of Flebogrif® in a population of patients with the incompetent great saphenous vein, who require surgical treatment.
NCT03904602
The purpose of this pilot study is to evaluate the effectiveness of EdemaWear® fuzzy wale longitudinal compression stockings on reducing lower extremity edema in hospitalized adult patients with a history of CVI who are at high risk of consequent venous leg ulcers (VLU) and patient experience with continuously wearing Edema Wear for up to five days
NCT05749471
Chronic Venous Disease (CVD) is a common clinical condition with a high prevalence in the western population that may affect quality of life (QoL) of affected patients for several adverse effects. Sexual dysfunction (SD) also partecipate in the QoL of people and has never specifically studied in CVD patients. The aim of this study is to study SD in CVD patients before and after treatment.

NCT01402921
Elastic MCT is a widely recognized and the consensus-approved treatment for chronic venous insufficiency (CVI).Efficacy evidence level is often insufficient (grade B or C), or based on studies carried prior to CEAP classification (2004). Item C3 of this classification relates to patients suffering from chronic venous disease and permanent oedema. Literature mentions only one study in which volume reduction in venous-induced oedema was primary endpoint. Indeed, 240 patients showed a 46.7 ± 8.2 ml reduction (SEM) after 12 weeks with a Class 2 compression sock (15-20 mm Hg at ankle). Volume is an accurate and reproducible quantitative measure considered nowadays as being gold standard when objectifying oedema variation. It is therefore particularly relevant in a C3-patient trial (CEAP classification). The main objective of the current study is to evaluate the clinical effect of Progressiv' MCT on volume reduction in permanent CVI-oedema after 3 months of treatment.
