[Late lysis therapy of chronic arterial occlusion. A new way to improve results (author's transl)].

Thrombolytic therapy with streptokinase was carried out 14 days after transcutaneous catheter recanalization in 17 patients. In 7 patients there was a disintegration of the re-occlusion and a distinct widening of the lumen of the canal created by means of the catheter. Complete removal of the thrombotic material from the vessel wall could be confirmed angiographically in 3 patients.
