MechanO-Chemical Ablation Versus CompreSSion

Conditions
Surgery
Varicose Veins
Interventions
Device: Endovenous Mechano- Chemical Ablation
Registration Number
NCT04441957
Lead Sponsor
Belarusian State Medical University
Brief Summary

This study will be looking at the effect of Endovenous Mechano-Chemical Ablation (MOCA) in addition to multilayer elastic compression bandaging vs multilayer elastic compression bandaging only in patients with incompetent great saphenous vein (GSV) and venous ulcers (VU's).

Detailed Description

The most severe form of chronic venous disease is venous ulceration with an overall prevalence of about 1% in the adult population. Venous ulcers significantly impair quality of life, and their treatment places a heavy financial burden upon healthcare systems.

To get the ulcer to heal, the current best treatment is to wear a compression bandage with multiple layers, with which about 60% of these ulcers will heal within 6 months.

There is evidence that treatment of the varicose veins by sahenous veins stripping will prevent the ulcer recurrence.

Recent studies have suggested that novel proceduress of superficial truncal reflux elimination, such as foam sclerotherapy or treating the saphenous veins with termal (laser or radiofrequency) ablation to seal it effectively, may help the ulcers to heal more quickly and increase recurrence-free rate. These techniques can be carried out in the outpatient setting and are much better tolerated by patients in comparison to surgery.

At the same time, no studies which compared compression plus endovenous mechanochemical ablation (MOCA) vs. compression alone in chronic venous ulcers have been conducted to date.

The aim of this study is to see whether treatment of varicose veins using MOCA helps with healing.
