目的探讨经小隐静脉顺行插管尿激酶溶栓治疗急性下肢深静脉血栓的方法和疗效。方法对37例急性下肢深静脉血栓患者行经小隐静脉顺行插管尿激酶溶栓术。结果所有病例均置管成功,接受尿激酶40万U/d,留管时间平均5.7(4～9)d。血栓完全溶解29例,部分溶解8例。结论经小隐静脉顺行插管尿激酶溶栓治疗急性下肢深静脉血栓操作简便,安全有效。 Objective To investigate the method and efficacy of intravenous urokinase thrombolysis through small saphenous vein in the treatment of acute deep venous thrombosis of lower extremities. Methods 37 patients with acute lower extremity deep venous thrombosis through small venous catheter drainage catheter urokinase thrombolysis. Results All patients were successfully catheterized, receiving urokinase 400,000 U / d, leaving an average of 5.7 (4 ~ 9) d. Thrombus completely dissolved in 29 cases, partially dissolved in 8 cases. Conclusions The small saphenous vein catheterization of urokinase thrombolytic therapy of acute lower extremity deep vein thrombosis is simple, safe and effective.
