【摘要】 目的 :评价置入下腔静脉滤过器预防各种因素所致静脉血栓脱落引起肺动脉栓塞的效果和安全性。方法 :2 0例下肢深静脉、盆腔静脉及下腔静脉血栓患者经右锁骨下静脉或股静脉置入钛质Bird’snestfilter(BNF) 2例 ,VenaTech LGMFilter(VTF) 18例 ;滤器置于肾静脉开口水平上方 3例、下方 17例 ;术后立即摄腹部平片及血管造影 ,观察滤器位置、形态及血流情况 ,并积极进行局部或全身溶栓治疗。结果 :全部滤器均成功放置 ,无任何并发症发生。随防 1～ 44个月亦无任何移位或倾斜、腔静脉阻塞及肺栓塞。结论 :置入下腔静脉滤过器是预防肺栓塞安全有效的方法。更多还原

【Abstract】 Objective:To evaluate the effectiveness and safety of inserting an inferior vana cava filter(IVCF) to prevent the pulmonary embolism due to detachment of the thrombus caused by varieties of factors. Methods: IVCF was placed in 20 cases with deep vein thrombosis in the lower extremities and deep pelvic veins. BNF was used in 2 cases, and VTF in 18 cases. IVCF was placed at the level below the opening of renal vein in 17 cases and the level over renal veins in 3 cases. The postoperative abdominal radiograph and angiography were taken to see the position and morphology of filter and the blood flow. 20 cases received local or systemic thrombolysis treatment immediately after the procedure. Results:All the filters were placed successfully through the common femoral veins(12 cases) or right subclavian veins(8 cases). No complication occurred. Followed up for a period of 1 to 44 months , no inclination and migration of filters or IVC occlusion nor pulmonary embolism were seen. Conclusions:IVCF placement is an effective and safe technique for preventing plumonary embolism.更多还原
