Catheter entrapment is a rare complication of intraaortic balloon counterpulsation caused by the formation of hard blood clot within the balloon itself. We present two cases of intraaortic balloon pump entrapment seen at the University Hospital, Boston. This phenomenon usually presents as a limb threatening vascular emergency. The entrapped catheter becomes stuck fast within the iliac system during withdrawal of the device, occluding arterial flow at that level. The etiology of this phenomenon, and a proposed management scheme is discussed. Preoperative radiographic determination of the level of entrapment may be necessary. We feel it is necessary to control the abdominal aorta prior to removal of an entrapped intraaortic balloon.
导管嵌顿是主动脉内球囊反搏的一种罕见并发症，由球囊本身内形成坚硬的血凝块引起。我们报告在波士顿大学医院见到的两例主动脉内球囊泵嵌顿病例。这种现象通常表现为威胁肢体的血管急症。在撤出装置过程中，被困导管在髂血管系统内牢固卡住，阻塞该水平的动脉血流。本文讨论了这种现象的病因及一种建议的处理方案。术前进行影像学检查确定嵌顿水平可能是必要的。我们认为在取出被困的主动脉内球囊之前控制腹主动脉是必要的。
