The data from many published studies indicate that thrombolytic therapy is more effective than heparin in achieving vein patency. The unproven assumption is that the degree of lysis observed on posttreatment venography is predictive of future venous valvular insufficiency and late (5-10 y) development of PTS. Preliminary evidence suggests that thrombolytic therapy reduces but unfortunately does not entirely eliminate the incidence of PTS at 3 years.
