目的总结腔内治疗时支架释放困难的处理经验。方法 3例腔内治疗中出现的支架释放困难问题是皱缩外周自膨式支架卡压释放系统、球囊扩张(球扩)支架因球囊破裂及支架边缘张开无法释放和回收,以及因主动脉扭曲导致主动脉支架卡压导入系统所致。分别采用支架内球囊扩张,大口径导鞘退出球囊破裂的球扩支架和球囊辅助导入系统回收等方法解决支架释放的困难。结果所有支架释放困难问题用腔内的方式得以解决,患者几乎没有额外的创口。结论支架释放困难的处理首选腔内方法,需要术者具备丰富的腔内操作经验。
Objective To summarize the treatment experience of difficult stent release during endovascular treatment. Methods 3 cases of endoluminization treatment stent appears to be difficult to release the problem of shrinking peripheral self-expanding stent compression release system, balloon dilatation (ball expansion) stent due to balloon rupture and stent edge can not be released and recovered, and due to Aortic distortions lead to aortic stent compression introduced into the system. The difficulties of release of the stent were solved by balloon expansion in the stent, balloon expansion stent with large-diameter sheath exit and balloon-assisted introduction system recovery, respectively. Results All stent release problems were resolved intracavity and the patient had almost no extra wounds. Conclusion Stent placement is the treatment of choice of the preferred endoscopic approach, requiring surgery who have extensive experience in the operation of the cavity.
