Mid-term recurrence rate of incompetent perforating veins after combined superficial vein surgery and subfascial endoscopic perforating vein surgery

BackgroundThis study investigated the mid-term (mean, 3.7 years) clinical results and the results of duplex Doppler sonographic examinations of subfascial endoscopic perforating vein surgery (SEPS) in patients with mild to severe chronic venous insufficiency (clinical class 2-6) and assessed the factors associated with the recurrence of insufficient perforating veins (IPVs).MethodsEighty patients with mild to severe chronic venous insufficiency undergoing SEPS were evaluated, and duplex findings, as well as clinical severity and disability scores before and after the operation, were compared. Patients with prior deep vein thrombosis (
