Endovascular rescue of a misshapen intracranial stent: report of two cases


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.
