[Fibrinolytic treatment with urokinase in older phlebothrombosis (author's transl)].

28 patients with 1 to 6 week old occlusions of the femoral and/or iliac veins as well as the subclavian veins were treated with a standardised urokinase-heparin-scheme. The fibrinolytic therapy was generally performed over a period of 7 to 14 days. In 2 patients, the 1 and 6 weeks respectively old thromboses of the iliac, femoral and tibial veins, and in 4 patients the 5 to 16 days old thromboses of the subclavian veins could be dissolved completely, 16 patients showed clinically and phlebographically a substantial amelioration. In 6 patients no marked success was found.
