ObjectiveTo evaluate the treatment effective of deep vein thrombosis (DVT) of low extremities. MethodsThe clinical data of 86 patients with DVT were analyzed retrospectively, which were divided into thromboectomy group (12 patients) and thrombolysis group (74 patients) according to the therapy methods. The thromboectomy group patients were treated by thromboectomy using Fogarty balloon catheter plus thrombolytie, thrombolysis group patients were treated by thrombolysis (urokinase or antithrombus enzyme of viper). ResultsThere were 8 cases healed, 4 cases relieved, 0 invalidated in the thromboectomy group and 15 cases healed, 50 cases relieved, 9 cases invalidated in the thrombolysis group at discharge. During 3-100 months of following up with an average 27 months, 10 cases and 62 cases were examined by Bultrasonic in the thromboectomy group and thrombolysis group, respectively, 6 cases were not damaged in the function of valves of the thromboectomy group, 9 cases were not damaged in the function of valves of the thrombolysis group. The rates of acute response, longtime patency, and normal valve in the thromboectomy group were higher than those in the thrombolysis group (Plt;0.05), the rate of post-thrombotic syndrome in the thromboectomy group was lower than that in the thrombolysis group (Plt;0.05). ConclusionsEarly thromboectomy is an effective way of restoring the fluency of deep vein and protecting the efficiency of the vein value organization, and reducing the sequela of DVT. Thrombolysis can only relieve the symptomation, but it can not protect the crawling and relapsing of thrombus.
