Tissue Engineered Veins in Patients With Chronic Venous Insufficiency

This study aims to evaluate the safety (incidence of adverse events including serious adverse events and clinical significant laboratory abnormalities) of personalized tissue engineered veins (P-TEV) with valves implanted in patients with severe chronic venous insufficiency (CVI). For each patient a segment of the femoral vein containing the non-functioning valve will be surgically replaced with a single P-TEV containing a functioning valve.

Respiratory and Physical Functions in Individuals With Chronic Venous Insufficiency

In the literature, it is still unclear whether individuals with chronic venous insufficiency are affected by edema, pain, respiratory muscle strength, respiratory functions, functional capacity, lower extremity strength and quality of life compared to asymptomatic healthy individuals and if there is a deterioration in these parameters, its level is still unclear. For this reason, in this study it was aimed to investigate edema, pain, respiratory muscle strength, respiratory function, functional capacity, lower extremity strength and quality of life in individuals with chronic venous insufficiency and asymptomatic healthy individuals and to compare these parameters between the two groups.

Effect of Photobiomodulation on Healing of Venous Leg Ulcers

Venous leg ulcers are a significant public health problem because of their prolonged duration, high recurrence rates, and economic, social, and quality-of-life effects. Compression therapy is the standard treatment; however, healing may remain slow. Photobiomodulation is being investigated as an adjunctive treatment to promote tissue repair and wound healing. This prospective, randomized, controlled, double-blind clinical trial will evaluate the efficacy of photobiomodulation combined with compression therapy in the healing of lower-limb venous leg ulcers. A total of 102 participants will be randomly allocated in a 1:1 ratio to an Experimental Group (n=51), receiving active photobiomodulation plus compression therapy, or a Control Group (n=51), receiving sham photobiomodulation plus compression therapy. Treatment will be administered twice weekly on Mondays and Thursdays for 16 weeks, totaling 32 sessions. The primary outcome will be the percentage reduction in wound volume over 16 weeks, estimated from wound area and depth. Secondary outcomes will include percentage reduction in wound area, change in wound depth, complete wound healing, adverse events, wound quality assessed using the Bates-Jensen Wound Assessment Tool, pain intensity and rescue analgesic use, health-related quality of life assessed using the SF-36, clinical severity assessed using the Venous Clinical Severity Score, and direct treatment costs. Wound area will be measured using the ImitoWound® application.

Clinical Study to Evaluate the Effectiveness and Health Economics of a Novel Portable Non-Pneumatic Active Compression Device (NPCD) for Lymphedema/Phlebolymphedema

An open-label, multi-center, prospective VA study to evaluate the effectiveness and health economics of a Novel Portable Non-Pneumatic Active Compression Device (NPCD) for lymphedema/phlebolymphedema

Investigation of Femoropopliteal In Situ Valve Formation With the InterVene System

To evaluate the safety and effectiveness of the BlueLeaf System for the restoration of venous competence for the treatment of symptomatic chronic venous insufficiency (CVI).

Venclose digiRF System Post Market Study

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.

The Influence of Laser Crossectomy With Different Wavelengths on Varicose Vein Progression

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.

Calcium Dobesilate After Radiofrequency Ablation for Varicose Veins

This study evaluates whether calcium dobesilate, a venoactive drug, improves recovery after radiofrequency ablation (RFA) for varicose veins. Patients with great saphenous vein insufficiency undergoing RFA will be randomly assigned to receive either calcium dobesilate (500 mg twice daily) or standard care alone. The treatment starts 7 days before the procedure and continues for 30 days after. The primary outcome is postoperative pain at day 7. Secondary outcomes include pain at days 14 and 30, quality of life, ecchymosis, and return to daily activities.

Clinical Study in Adult Patients With Purulent-inflammatory Processes of the Skin and Soft Tissues, Phase I-II of the Wound Process

The purpose of this study is to estimate efficiency, tolerance, safety of "Foscelantan, medicinal plate 4.0x5.0 cm in package No. 1" among adult patients who have purulent-inflammatory processes of the skin and soft tissues due to the neuropathic form of diabetic foot syndrome or chronic venous insufficiency, phase I-II of the wound process.

Elastic Compression Stockings and Varicose Veins Recurrence

Hypothesis. Regular using of Class 1 below-knee graduated compression stockings (RAL GZ 387 standard) compared to the absence of elastic compression will reduce the risk of clinically significant varicose veins recurrence at 12 months after endovenous thermal ablation of the great saphenous vein and elimination of varicose tributaries.
