[Operation on varicose, especially in the malleolar region (author's transl)].

The great number of people with varicosities and the relatively high percentage of venous pathology among this group shows the importance of their detection and treatment. The results achieved in more than 1000 operations on varicose legs underline the great benefits arising from surgical treatment of the varicose saphenous vein. The treatment of chronic venous insufficiency in the malleolar region has been aided by the use of the Klapp tenotoma. The simple and atraumatic manipulation of this instrument enables the surgeon to overcome the most important obstacles in this region, the perforator veins (Cockett I, II), the venous leg ulcer and the corona phlebectatica paraplantaris. Conscientious postoperative supervision of the patient by the surgeon personally or by a dermatologist trained in this speciality is an essential condition for the successful operative treatment of varicose veins.
