Inadvertent deformation and displacement of a fully deployed closed-cell intracranial nitinol stent may occur with manipulation of other devices through or beyond them. Such displaced and deformed stents may obstruct the lumen, risking formation of thromboemboli, and/or fail to no function as a scaffold to assist with coil embolization. We review two such cases whereby an Alligator retrieval device (ARD) (ev3, Irvine, California, USA) was used to salvage a deployed misshapen intracranial stent.
在通过或超越其他设备进行操作时，完全展开的闭孔颅内镍钛诺支架可能会发生意外变形和移位。这种移位和变形的支架可能会阻塞管腔，有形成血栓的风险，和/或无法作为支架协助线圈栓塞。我们回顾了两例使用鳄鱼取栓装置（ARD）（ev3，加利福尼亚州欧文，美国）来抢救展开后形状异常的颅内支架的情况。
