临时性腔静脉滤器在静脉血栓溶栓治疗中的应用

目的：探讨临时性腔静脉滤器置入在外周静脉血栓患者溶栓治疗中预防异位栓塞的应用价值。方法：10例下肢静脉血栓及1例永存动脉干合并右颈内静脉血栓的患者，分别经静脉置入临时性腔静脉滤器后，用大量尿激酶顺行或全身静脉溶栓治疗。结果：11例患者经7－15d的治疗后症状消失，血栓完全或部分溶解，血管开通，取出临时性腔静脉滤器，未出现并发症及异位栓塞。结论：置入临时性腔静脉滤器在外周静脉血栓患者溶栓治疗中是预防静脉血栓脱落导致异位栓塞的有效方法。

Temporary vena cava filter for the thrombolytic treatment of venous thrombosis

Objective To study the value of the temporary vena cava filter in the prevention of ectopic embolism formation in cases with thrombolytic therapy of venous thrombosis.Methods Of 11 patients, 10 suffured from venous thrombosis of lower limb and 1 from thrombosis of right internal jugular vein with persistent truncus arteriosus were treated by inserting permanent or temporary vena cava filter via median vein. Results In all 11 case control of symptoms followed this treatment occurred 7 to 15 days, thrombi were completely or partly dissoluted, the blood vessels recanalized, and finally removed the temporary vena cava filter. There were no complication and ectopic emboli related to thrombolytic therapy. Conclusions Our observation indicated that temporary vena cava filter insertion is safe and effective to prevent ectopic embolism in thrombolytic therapy of venous thrombosis.
