[Ulcus cruris--vascular etiology and surgical treatment options].

Leg ulcers comprise a problem with various contributing factors requiring selective therapy adapted to the underlying cause. The majority can be classified as arterial (approx. 20%) or venous (approx. 80%) ulcers. Arterial ulcers as well as most mixed (arterial-venous) ulcers can be treated by arterial reconstruction and subsequent skin grafting, with additional ligation of perforator veins or (segmental) stripping of the saphenous vein. Leg ulcers due to chronic insufficiency of the deep venous system are most often the result of previous deep venous thrombosis followed by recanalization and development of a postthrombotic syndrome. Compression regimens remain standard therapy with emphasis on preventing ulcer formation. Ulcer healing can be achieved by compression therapy although recurrence rates are high. Surgery is not the treatment of first choice for leg ulcers, however, in selected cases surgical therapy is indicated. To prevent recurrence, continued consistent compression, keeping the patient well-informed and offering supportive guidance are imperative.
