Endoscopic ligation of perforating veins using a mediastinoscope

Incompetent perforating veins play a major role in venous ulceration and recurrence of varicose veins. To reduce postoperative wound problems associated with classic subfascial exploration of the lower leg, endoscopic approaches have been developed. We describe a technique that makes use of a mediastinoscope to explore the subfascial area. This inexpensive and readily available instrument is present in most operating rooms. Although a learning curve must be anticipated, the results of this technique in retrospective studies are promising.
