目的 探讨用微创介入方法清除医源性静脉血管内异物的疗效、技术要点及并发症防治.方法 5例由静脉置管引起的医源性血管内异物均采用右股静脉入路,选用不同规格的抓铺器抓取异物.结果 所有病例均成功取出异物,手术成功率100%,未发生血管破裂、肺动脉栓塞等严重并发症.结论 微创方法用抓铺器取医源性静脉置管血管内异物创伤小,成功率高,可避免外科手术.%Objective To investigate the effectiveness. technical points and complications of the minimally-invasive treatment for iatrogenic intravenous foreign bodies. Methods Five patients with iatrogenic intravenous foreign bodies due to the fracture or shift of venous catheter were enrolled in this study.By using grasping device. which was inserted into the target vein via right femoral vein, the foreign bodies within the venous system were successfully eliminated. Results The vascular foreign bodies were successfully removed in all five patients, with a success rate of 100％. No operation-related complications,such as vascular rupture, pulmonary embolism, etc. occurred. Conclusion As a minimally-invasive technique , the use of grasping device for removing the iatrogenic vascular foreign bodies has higher success rate; thus, major surgical procedures can be avoided.
