Endoscopic technique for subfascial perforating vein interruption.

Surgical treatment of incompetent perforating veins of the lower leg performed openly carries considerable morbidity associated with wound healing. Newer minimally invasive techniques offer an effective treatment alternative that avoids the lengthy incisions of the classical subfascial ligation techniques. The authors report a simple and quick two-port endoscopic method for clipping incompetent perforating veins of the lower leg using commonly available endoscopic instrumentation. The technique is unique in its use of a balloon dissector to rapidly establish the subfascial working space.
