Abstract

Background: In the last decade, minimally invasive endothermal (RFA, Laser) ablation techniques have replaced surgery for the treatment of superficial venous insufficiency to reduce postoperative complications and recovery time and to improve quality of life. To avoid the risks of nerve damage and need for tumescent anesthesia to improve patient comfort, an endovenous mechanochemical ablation (MOCA) has been introduced recently. Method: Retrospective descriptive study. Conclusion: A total of 28 patients with varicose veins were treated with ClariVein technique, an average age of 52 years, female accounted for 71.4%. Clinical grade according to CEAP from stage C2 to C5. The average intervention time was 25 minutes, the average volume of Sclerosant used was 8.5ml. The results after the intervention were technically successful at 100%, after 4 weeks, 27 cases were recorded (96.4%), and completely blocked by doppler ultrasound, the patient's clinical symptoms improved significantly, numbness and heaviness in the legs, 1 case (3.6%) had distal regurgitation. There were no notable complications such as deep vein thrombosis, sensory nerve damage in the lower legs, no skin necrosis or infection. There were only 2 cases (7.1%) of mild pain along the great saphenous vein, so no further treatment was needed, the patient was completely satisfied with the treatment result. Result: Mechanochemical ablation with the ClariVein system is safe and effective.
