Abstract:Objective: To investigate the therapeutic effect of temporary inferior vena cava in the treatment of thrombolytic and transposed thrombolysis in patients with acute iliofemoral vein thrombosis. Methods: From March 2012 to March 2016, 60 patients with acute iliac femoral vein thrombosis in our hospital were retrospectively analyzed. They were divided into catheter thrombolysis group (n=30) and dorsalis pedis thrombolysis group (n=30) according to the treatment. The clinical effects of the two treatment methods were compared after treatment, including the change of the circumference of the lower limbs, the rate of body swelling, the dosage of urokinase, the time of hospitalization, the rate of thrombolysis, the occurrence of thrombolysis, the long-term patency and the valvular function. Results: Catheter circumferential thrombolysis group before and after treatment, thigh and calf circumference difference and limb swelling rate were significantly higher than those in the dorsalis pedis thrombolysis group, the difference was statistically significant (P <0.05). The amount of urokinase and the time of hospitalization in the treatment of thrombolytic therapy were significantly lower than those in the back thrombolytic group (P <0.05). 2 weeks after treatment, the thrombolytic rate in the catheter thrombolysis group was significantly higher than that in the dorsalis pedis thrombolysis group, and the incidence of complications was significantly lower than that in the dorsalis pedis thrombolysis group. The above differences were statistically significant (P <0.05). Follow up for 18 months, venous catheterization rate in catheter thrombolysis group was significantly higher than that in the dorsalis pedis thrombolysis group, while the incidence of thrombotic syndrome (PTS) and thrombosis recurrence rate were significantly lower than those in the dorsalis pedis thrombolysis group, the difference was statistically significant (P <0.05). Conclusion: Thrombolytic therapy via small saphenous vein for patients with acute iliac femoral vein thrombosis has many advantages, such as good curative effect, short treatment time and low incidence of complications. It is worthy of further clinical application.
