Fogarty球囊导管在急性自体动静脉内瘘栓塞中的应用

Removal of the acute thrombus in dialysis vascular access with Fogarty catheter

目的观察应用Fogarty球囊导管处理动静脉内瘘血栓形成的效果。方法采用Fogarty球囊导管对4例急性自体动静脉内瘘血栓进行取栓术。结果Fogarty球囊导管取栓术4例,1例患者重新栓塞,3例仍在使用,最长22个月。结论Fogarty球囊导管处理动静脉内瘘血栓形成,尤其有利于保存患者的原瘘管血管,延长瘘管使用寿命。

Objective To evaluate the use of Fogarty catheter to remove thrombi in dialysis vascular access. Methods The thrombosed vascular access was incised and a 3 Fr catheter was inserted with the balloon not inflated. After the Fogarty catheter broke through the thrombus, saline was infused into the balloon and the catheter was then pulled to remove the clots. Results The operation was performed in 4 patients. In all of them, hemodialysis was resumed within 24 hours after the removal. The access flow was restored, allowing satisfactory hemodialysis in 3 patients, while thrombosis recurred in 1 patient and the blood flow rate there was poor. Three of the 4 vase, ular accesses were maintained functioning well, with the longest having been serving for 22 months. Conclusion Removing the vascular access thrombus with Fogarty catheter helps to preserve the problem vascular access and prolong its working life.
