Abstract:Objective To compare the clinical effect of catheter-directed thrombolysis (CDT) in treating deep venous thrombosis (DVT) of lower extremities through the ipsilateral popliteal vein, the ipsilateral great saphenous vein and the contralateral femoral vein. Method Totally 75 patients with DVT treated with CDT were selected from March 2015 to March 2017 in our hospital. According to the different approaches of CDT, the patients were divided into the ipsilateral popliteal vein group, the ipsilateral great saphenous vein group and the contralateral femoral vein group, 25 cases for each one. Ipsilateral lower extremity swelling rate, degree of smooth improvement and incidence of complications of the three approaches were compared. Results There were no significant differences in all the factors above among the groups (P > 0.05). Conclusion Good clinical effect can be achieved through the three approaches of CDT for DVT patients. Generally, more easily punctured approach through the ipsilateral popliteal vein or ipsilateral large saphenous vein can be chosen in advance, otherwise, approach through the contralateral femoral vein can be considered.
