The Impella is a percutaneously placed intra-arterial flow pump positioned across the aortic valve for circulatory support. A limitation of the Impella is that it lacks a central wire channel, to maintain intra-arterial wire access when removing the device. Open surgical arterial cutdown is needed for the removal of the Impella CP placed emergently, without the use of preclose sutures. This case review describes an alternative removal method for the aforementioned occasions.
Impella是一种经皮置入的动脉内血流泵,跨过主动脉瓣放置以提供循环支持。Impella的一个局限性在于它没有中心导丝通道,在移除该装置时无法维持动脉内导丝通路。紧急放置的Impella CP移除时,若不使用预置闭合缝线,则需要进行开放手术动脉切开。本病例回顾描述了针对上述情况的另一种移除方法。
