下腔静脉滤器植入对治疗下肢深静脉恤栓的探讨

目的总结下腔静脉滤器（IVCF）植入后取栓及溶栓治疗在下肢深静脉血栓中的应用经验。方法分析14例经下肢深静脉造影证实下肢深静脉血栓形成（DVT）的病例资料，先行下腔静脉滤器植入，后在透视引导下用大腔导管取栓及溶栓导管局部溶栓治疗。结果下腔静脉滤器植人全部成功，取栓及溶栓治疗显效12例，有效2例，无肺动脉栓塞症（PTE）及严重出血发生，下肢症状消失。结论腔静脉滤器植入后取栓及溶栓治疗DVT，疗效显著。

Approach on implantation of inferior vena cava filters for deep vein thrombosis of lower limb

Objective To sum up the application experience of embolectomy thrombolytic therapy after implantation of inferior vena cava filters （1VCF） for deep vein thrombosis. Methods Data of 14 cases confh＇med deep vein thrombosis （DVT） of lower limb by deep vein venography was analyzed. After inferior vena cava filters implantation, transcatheter embolectomy or thrombolytic therapy was performed under the guidance of fluoroscopy. Results Inferior vena cava filters implantation were succeeded in all cases. 12 cases with embolectomy or thrombolysis got excellent effects, and 2 cases got improved, without pulmonary embolism （PTE） and serious bleeding. The symptoms of lower limb disappeared. Conclusion Curative effect is notable for DVT after implantation of caval vein filter before embolectomy or thrombolysis.
