Venous ulcers significantly impair quality of life, and their treatment places a heavy financial burden upon healthcare systems.\n\nTo 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.\n\nThere is evidence that treatment of the varicose veins by sahenous veins stripping will prevent the ulcer recurrence.\n\nRecent 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.\n\nAt 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.\n\nThe aim of this study is to see whether treatment of varicose veins using MOCA helps with healing.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '18 Years', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'Patients with GSV incompetence and C6 were included in in the prospective consecutive case study if they satisfied the selection criteria.', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
