A prospective study of streptokinase and heparin in the treatment of deep vein thrombosis.
2009
ABSTRACT. In a prospective trial, 42 medical patients with a history of deep vein thrombosis of less than five days were allocated at random to treatment with streptokinase or heparin. Only patients with extensive thromboses were included. Streptokinase was given in a loading dose of 250000 IU and a maintenance dose of 100000 IU/hour for 4 days as a mean. Heparin was given in a loading dose of 15 000 IU and a maintenance dose of 20000–50000 IU/day. The therapeutic results were evaluated by phlebography. Significant thrombolysis occurred in 71.4% of 21 patients treated with streptokinase and in 23.8% of the 21 heparin-treated patients. Using the X2-test for overall association, this difference was statistically highly significant (p=0.002). Three patients in each treatment group experienced major bleeding, two in each group requiring blood transfusions. Minor bleeding and slight rise in temperature were encountered more often in the streptokinase than in the heparin group. It is concluded that patients with acute deep vein thrombosis with proximal extension of the thrombus beyond the calf veins should be offered a therapeutic trial with streptokinase.
