Feasibility of Permanent Stenting with Solitaire FR as a Rescue Treatment for the Reperfusion of Acute Intracranial Artery Occlusion

A 55-year-old man with acute ischemic stroke, presenting with an initial NIHSS score of 22. A, A right internal carotid angiogram shows occlusion of the right middle cerebral artery M1 portion. B, Initial placement of the Solitaire stent. A right internal carotid angiogram shows visible anterograde flow in the right middle cerebral artery M1 portion. C, A 5-minute delayed right internal carotid angiogram after thrombectomy using the Solitaire stent shows repeat buildup of thrombus and reocclusion. D, After 3 passages of the Solitaire stent with recurrent reocclusion, the decision for a permanent stent was made. A right internal carotid angiogram during the intravenous infusion of glycoprotein IIb/IIIa inhibitor shows a patent lumen of a temporarily deployed Solitaire stent. E, A 30-minute delayed angiogram after detachment of the Solitaire stent reveals complete recanalization. F, A follow-up angiogram at 3 months reveals a patent right middle cerebral artery with no evidence of in-stent restenosis at the M1 portion. The patient had an mRS score of 1 at 3 months.
