Technical procedure of two-port system subfascial endoscopic perforator vein surgery (TPS-SEPS)

Abstract

It has long been noted that incompetent perforating veins contribute to the development of chronic venous insufficiency and recurrent varicose veins that are complicated by skin ulcerations or liposcleroderma. For these conditions, severing of incompetent perforating veins is an effective surgical treatment. However, severing of incompetent perforating veins by a direct approach has become less commonly performed because of the excessive invasiveness of the procedure itself. We referred to 37 cases (44 legs) of varicose veins with or without active venous dermatitis, who underwent the two-port system subfascial endoscopic perforator surgery, which we devised (hereafter referred to as TPS-SEPS). According to this method, incompetent perforating veins can be severed without surgical intervention in the lesion. The criteria for insufficiency of the perforating veins (IPVs) are reverse flow demonstrated on a color-flow duplex and a caliber more than 3 mm in diameter. One hundred forty one out of one hundred fifty two IPVs were processed. A mean of 3.21 perforating veins per patient was severed using ultrasonic coagulation-incision apparatus. From these 37 cases we conclude that TPS-SEPS provides a useful tool for the surgeon interested in treating severe chronic venous insufficiency same as the single-port technique. Our TPS-SEPS is a relatively simple operation, but its skill is dependable and provides lower invasiveness than other operation procedure. From now on, it is necessary to unify the authorized name of the endoscopic surgery of perforating veins and is also important to define the indication of this method for the primary varicose veins without stasisdermatitis.
