[Results of endoscopic perforating vein dissection].

The subfascial discision of insufficient perforating veins is considered the most effective therapeutic principle for the treatment of postthrombotic disturbances of the skin as well as for trophic disturbances caused by varicose. A new endoscopic technique allows to be sectioned them under direct view control with little trauma. In the period from November 1986 to April 1990 61 patients underwent an endoscopic sectioning of perforating veins. Perforating veins have most frequently been separated in the area of the Cockett group (153), the 24 cm perforating vein (74) and in the area of the Boyd group (63). Two patients (3.3%) with trophic disturbances of the skin in the area of the shank showed disturbances of wound healing after the operation. First results of the follow-up examination 3-37 months postoperative have proved good (45%) to very good (40%) results. Criteria, which were observed, were pains in the leg, disturbances of sensibility, swellings and relapsed varices. Only two patients proved a bad result. Insufficient perforating veins in the area of the shank were not found by one of the 61 operated patients. Referring to a staging of chronic venous insufficiency it can be said that with the exception of the two patients above mentioned there is a ranging to a more favourable stage or to a complete treating.
