Akpinar s, yilmaz g.Spontaneous solitaire¿ ab thrombectomy stent detachment during stroke treatment.Cardiovascular and interventional radiology.2015;38(2):475-478.Doi:10.1007/s00270-014-1022-y.Medtronic literature review found a report of patient complications in association with a solitaire ab.The purpose of this article was to present the case of spontaneous solitaire stent retriever detachment during stroke treatment for a middle cerebral artery m1 occlusion resulting in progressive thrombosis.The following intra- or post-procedural outcomes were noted: after reaching the occlusion site using a rebar 27 microcatheter, the solitaire ab was distally unsheathed and allowed 4 min to deploy.While drawing the deployed retriever stent, resistance to withdraw was noticed and they partially resheathed the stent into the delivery microcatheter to free the stent where it was entangled.During this maneuver, the thrombectomy stent spontaneously detached.Following control runs, the thrombus progressed from the occlusion at the mca medioinferiorly to the distal ica segment without responding to two consecutive infusions of abciximab.Because there was no recanalization at the occlusion site and access distal to the detached stent with the micro guidewire was not achieved, the proximal branch of the mca was catheterized and another solitaire stent was deployed to capture the first stent.After two unsuccessful attempts through the mca route, the right anterior cerebral artery (aca) a1 segment was catheterized.The distal markers of the second stent deployed at the aca a1 segment caught the proximal strands of the detached first stent, and removal of both stents was achieved using the 8fr guiding catheter.After this maneuver, the occluded mca m1 segment was recanalized, resulting in a tici score of 2b.The patient was kept in an intensive care unit because of poor oxygen saturation.A ct after 6 hours showed a non-progressive ecass hi type 2 hemorrhage at the right putamen, and a right mca repeat stroke, which was assumed due to atrial fibrillation and low ejection fraction.
