RESUMO
Objective To evaluate the feasibility of beside color Doppler ultrasound-guided popliteal vein catheter in treatment of lower extremity deep venous thrombosis (LEDVT).Methods Data of 50 patients with unilateral LEDVT were reviewed,including 25 cases underwent beside color Doppler ultrasound-guided catheter thrombolytic therapy (catheter thrombolytic group) and 25 cases underwent systemic thrombolysis and anticoagulant therapy (anticoagulant thrombolysis group).The cure rate,hospitalization time and the bilateral diameter differences were compared between the 2 groups.Results Thrombolytic effective rate was 100％ in both the 2 groups.Thirty patients were clinical cured,including 22 cases in catheter thrombolytic group and 8 cases in anticoagulant thrombolysis group.The cure rates were significantly different between the 2 groups (88.00％ [22/25] vs 32.00％ [8/25],x2 =16.333,P＜ 0.001).The hospitalization time of catheter thrombolytic group ([12.32 ± 1.49] days) was shorter than that of anticoagulant thrombolysis group ([16.44±2.95]days;t=-6.426,P＜0.001).The diameter differences between LEDVT side and contralateral side of the upper and lower 15 cm form knees in catheter thrombolytic group showed no statistical difference compared with anticoagulant thrombolysis group before the treatment (both P＞0.05),while of catheter thrombolytic group were smaller than those of anticoagulant thrombolysis group after the treatment (both P＜0.05).And the bilateral diameter differences before the treatment were larger than those after the treatment in both groups (all P ＜ 0.05).Conclusion Both of beside color Doppler ultrasound-guided catheter thrombolytic therapy and systemic thrombolysis and anticoagulant therapy can be used to treat LEDVT,while the efficacy of ultrasound-guided catheter thrombolytic therapy is better.
