Treatment of deep-vein thrombosis with intermittent streptokinase and plasminogen infusion.

17 consecutive patients who presented with extensive deep-vein thrombosis, confirmed by phlebography, were included in this study. Of 12 patients who received streptokinase and plasminogen infusion, complete lysis of thrombi was obtained in 8 and partial but extensive lysis in 4. In contrast, thrombi remained unchanged in each of 5 patients who received the same doses of streptokinase infusion only.
