In patients with varicose vein a duplex ultrasound is absolutely necessary prior to surgery in order to check the deep and the superficial vein systems. A standard classification is recommended to describe the type of venous insufficiency. Teleangiectasis and small varicose veins can be treated by sclerotherapy, but laser-therapy gets more and more popular. The inverting (partial)stripping of the greater and/or lesser saphenous vein avoiding nerve damage has gained popularity as did the miniphlebectomy. Newer methods using heat by radiofrequency order cryosurgery should generate less complications and have to show similar long term results than the classical procedures. Subfascial endoscopic perforator vein surgery (SEPS) is effective. Local or extended fascioctomy followed by skin transplantation in patients with recurrent ulcerations is considered as an option of therapy.
