Investigation of the influence of combined oral contraception on the development and progression of chronic venous diseases
NCT07123285
This randomized, controlled, double-blind clinical trial will evaluate the efficacy of photobiomodulation (PBM) combined with compression therapy in the healing of venous ulcers (VUs) in the lower limbs. A total of 96 participants will be allocated into two groups: Experimental Group (PBM + compression) and Control Group (sham PBM + compression). Treatments will be administered twice weekly for 16 weeks (32 sessions). The primary outcome will be complete wound healing. Secondary outcomes include changes in ulcer area and volume, pain (VAS), quality of life (SF-36), clinical severity (VCSS), wound quality (Bates-Jensen Scale), infrared thermography, and treatment costs. Data will be analyzed using ANOVA or Kruskal-Wallis, chi-square or Fisher's exact test, and Kaplan-Meier survival analysis, with a significance level of p \< 0.05.

NCT07236307
The goal of this single-arm clinical trial is to learn whether overnight limb elevation using the UZit® device can improve symptoms and signs of chronic venous disease (CVD) in adults. The main questions it aims to answer are: Does one week of overnight UZit® use improve quality of life in patients with CVD? Does UZit® use reduce ankle circumference and are there any adverse events associated with its use? Because there is no comparison group, all participants will use the UZit® device to determine whether these effects occur. Participants will: Use the UZit® device every night for one consecutive week. Follow their vascular surgeon's existing recommendations (e.g., compression stockings, venotonic medications). Complete the CIVIQ-14 questionnaire at baseline and after one week of using the device to assess quality of life. Measure ankle circumference twice daily (upon waking and before bedtime) using a digital tape measure, following marked anatomical points. Report any symptoms-including low back pain-and rate their satisfaction with the device on a 0-5 scale.
NCT05489588
This study is a prospective, non-randomized, multicenter, single-arm, clinical study to evaluate the performance, safety and efficacy of the GORE® VIABAHN® FORTEGRA Venous Stent (formerly known as GORE® VIAFORT Vascular Stent) for treatment of symptomatic iliofemoral venous obstruction.
NCT07185386
The primary objective of the study is to evaluate, after 12 weeks (visit 3, V3), the effect of the combination of diosmin, hesperidin, bromelain, and Ruscus aculeatus (Vesvein Gambe) on any changes in the total quality of life score, measured using the CIVIQ-20 (Chronic Venous Insufficiency Quality of Life Questionnaire), compared to baseline (visit 1, V1), in individuals with subjective symptoms in one or both lower limbs attributable to Chronic Venous Disease (CVD).
NCT06834555
Chronic venous disease is a common disease of the lower limbs. Severe CVD can lead to lower limb swelling, pigmentation, and repeated skin ulceration, which seriously affects patients' quality of life. About 10.5% to 92.7% of CVD patients with recurrent varicose veins had insufficient perforating veins. Treatment of these IPVs can promote venous ulcer healing and reduce the recurrence rate of venous ulcers. Accurate assessment and positioning of insufficient perforating veins in the lower leg is a key step in developing a personalized treatment strategy. At present, Color Doppler ultrasonography performed in the upright position in combination with the Valsalva maneuver or local pressure of the limb is regarded as the "gold standard" for the diagnosis of perforating veins insufficiency. However, in China, a large number of perforating veins insufficiency are diagnosed by venography. Because the majority of Chinese vascular surgeons are not versatile in vascular ultrasound examination and venous ultrasound protocols vary from institution to institution. A non-functioning valve in an insufficient perforated vein allows blood to flow retrograde from a deep vein to a superficial vein. Some researchers have shown that the venous blood temperature of deep veins is higher than that of superficial veins. Thus, the retrograde flow of "warm blood" from the deep vein to the superficial vein increases the skin temperature located on the insufficient perforated vein. This study tested the feasibility of a smartphone and its compatible portable thermal imaging device as a tool for assessing insufficient perforated vein. The objective is to study the sensitivity and specificity of smartphone thermal imaging in diagnosing and locating the insufficient perforated vein in CVD patients.

NCT02907320
Chronic Venous Disorder is the most prevalent vascular disease. It is multifactorial pathology that has an important impact on quality of life and represents a significant public health concern, due to its very high frequency in all European and American (north and south) countries. Venous pathology develops when venous pressure is increased and return of blood is impaired through several mechanisms. Wish induce leg symptoms (tingling, aching, burning, pain, muscle cramps, sensation of swelling, sensations of throbbing or heaviness, itching skin, restless legs, leg tiredness and/or fatigue. The aims of this research is to study the effects on microcirculatory activity (activity on very small vessels) of CYCLO 3 ® FORT, MPFF (Micronised Purified Flavonoid Fraction) and Placebo after 8 week of treatment by Microscan, and Duplex, two imaging non-invasive technologies will be performed to obtain measurements of microcirculatory parameters in standardized and reproducible conditions for all the participants. In addition, will assess, in blood samples, the inflammatory biomarkers .
NCT01801891
This study aims to determine if the use of surface neuromuscular electrical stimulation, applied to various motor points on the lower limb to elicit muscle contraction when combined with compression bandaging accelerates the rate of venous leg ulcer healing.
NCT01368159
The trial objectives are to compare efficacy relative to pain, along the route of the vein following echoguided endovenous injection of sclerotherapeutic foam into the Great Saphenous vein, of class III microfibre compression (centred at 25 mm Hg) versus class I (10-15 mm Hg) versus class III cotton compression (20 to 36 mm Hg) over 21 days. The main contrast will be the comparison between the first two groups mentioned. All other contrasts will be secondary. The "Class I compression" versus "The two class III compressions" contrast will also be studied. Efficacy will be measured by totalling the VAS scores for maximum pain experienced since the morning and evaluated by the patient at the end of the day. Consumption of analgesics or the number of days of analgesic treatment necessary for the 3 compression types used will be compared. One of the trial objectives is also to show that regular use of a class III compression product leads to a reduction in complications following sclerosis (by reducing the number of non-serious/serious complications specific to sclerosis: matting, pigmentation, inflammation, development of sclerosis requiring drainage, DVT, pulmonary embolism, etc.). The trial also aims to compare the rate of successful sclerosis between the three devices, success being defined by complete or partial occlusion of the great saphenous vein, leading to the disappearance of reflux at the crural level. The other secondary objectives will be patient evaluation of comfort, ease of putting on and taking off the compression hose and a global appreciation of the procedure for echoguided endovenous injection of sclerotherapeutic foam into the great saphenous vein, followed by wearing compression hose.
