Subfascial endoscopic perforating veins ablation in treating chronic venous insufficiency of lower extremities

Objective To evaluate the effect of subfascial endoscopic perforating veins ablation in treating chronic venous insufficiency of lower extremities. Methods A retrospective study was carried out on 18 patients( 20 limbs) with chronic venous insufficiency treated by subfascial endoscopic perforating veins ablation. Results 69 perforating veins were detected in the medial calf of 20 limbs,including 62 incompetent perforating veins and 7 competent perorating veins. 65 perforating veins were ligated but 4 were not found.Apart from the clinical score of pigmentation, there were sigificant decreases in all the mean scores postoperatively (P0.01). After 3 months follow up, ulcers of 19 limbs healed (88.9%) and none recurred. Conclusions Subfascial endoscopic perforating veins ablation in treating chronic venous insufficiency combined with incompetent calf perforating veins in the lower extremities is safe, effective,and feasible methed.It sufficiently improves the clinical symptoms and signs in chronic venous insufficiency with the lower complications rate, especially suitable for the patients with the venous ulceration resulted from incompetent perforating veins.
