[Surgery of perforant veins].

The eradication of incompetent perforating veins combined with fasciotomy is a successful concept in the therapy of leg ulcers. Both can be achieved by endoscopy. Under endoscopic control, the medial, anterior, and posterior groups of perforating veins can be prepared at different levels and dissected after bipolar coagulation. Under endoscopic control the superficial fasciae of the leg are split.
