[Phlebographic follow-up of successful fibrinolytically-treated deep thrombophlebitis].

The present study deals with long-term results in patients in whom deep venous occlusions were removed by fibrinolytic treatment. For this an ultrahigh streptokinase regimen was used. The average follow-up period was 18.9 +/- 6.7 months. The number of patients investigated was 27. In the group of femoral veins formerly cleared by fibrinolysis 2 of 21 (9.5%) were recorded as reoccluded. An unexpected removal of a femoral thrombosis still in existence immediately after fibrinolytic therapy was seen in one patient and evaluated as a late lytic event. In the group of iliac vein thrombosis cleared by fibrinolytic treatment no reocclusions occurred. In conclusion it can be said that the reocclusion-tendency of veins cleared by fibrinolysis is relatively low. This finding constitutes a special incentive for fibrinolytic treatment of deep vein thrombosis.
