下腔静脉滤器植入术预防肺动脉栓塞25例临床分析

Application of the inferior vena cava filter in the prevention of the risk of pulmonary emboli:An analysis of 25 cases

目的:探讨经皮穿刺下腔静脉滤器植入术在治疗下肢深静脉血栓中预防肺动脉栓塞的作用。方法:常规行下腔静脉造影,了解并确定下腔静脉和释放途径无血栓形成,经股静脉或颈静脉穿刺将滤器放置到肾静脉开口下的下腔静脉。结果:本组病例均释放成功,其中2例双下肢深静脉血栓的患者经颈静脉释放,其余均经股静脉释放,2例在超声定位下释放。术后随访1～18个月,均无肺栓塞发生。结论:经皮穿刺下腔静脉滤器植入术操作简便,可以有效地预防下肢深静脉血栓患者中导致致命的肺动脉栓塞的发生。

Objective. To evaluate the effectiveness of the vena cava filter in the prevention of pulmonary embolism in the treatment of deep venous thrombosis （DVT） of the acute lower limb. Methods. DVT involved in the right lower limb in 8, the left one in 15 cases and the both limbs in 2 cases. 25 filters were implanted in the inferior vena cava below the renal vein in 25 DVT cases. Results.The implantation was successful in all cases. Two cases with DVT in the both limbs were implanted through the jugular vein,all but the two were through the femoral vein,and the filter implantation was finished in 2 cases under the guidance of ultrasound scanning. During the follow--up period ranged from 1 to 18 months, no pulmonary embolism occurred. Conclusion.The inferior vena cava filter is easy and safe to be implanted and can successfully prevent pulmonary embolism.
