Permanent implantation of the Solitaire device as a bailout technique for large vessel intracranial occlusions.

The Solitaire (Medtronic Inc, Mansfield, Massachusetts, USA) is a stentriever device for endovascular treatment of acute ischemic stroke. Temporary endovascular bypass and mechanical thrombectomy are well-described applications of this device. However, few reports of permanent stent placement have been published. We present a series of five cases in which the Solitaire stent was implanted to restore distal flow after failure of conventional mechanical thrombectomy. All patients presented with large vessel occlusions with thrombi that were resistant to retrieval or suction-aspiration. Immediately after implantation the patients were given a loading dose of abciximab and then transitioned to dual antiplatelet therapy within 24 hours. Our series suggests that permanent deployment of the Solitaire may be considered as a bailout technique in the treatment of cerebral large vessel occlusion. Long-term antiplatelet therapy is required after deployment. © Author(s) (or their employer(s)) 2019. No commercial re-use. See rights and permissions. Published by BMJ.
