- W2897092256 abstract "Introduction: Symptomatic internal carotid artery occlusion (ICAO) can lead to subsequent neurologic decline, recurrent stroke, and mortality. We sought to evaluate safety and feasibility of endovascular revascularization for ICAO without tandem intracranial large vessel occlusion (LVO). Methods: This is a retrospective cohort analysis of all patients presenting to a single academic center with ischemic stroke and ipsilateral, cervical ICAO from November 2003 through April 2016. Patients were excluded if pre-procedural angiography demonstrated tandem LVO or if patients were known to have chronic ICAO. Study endpoints included discharge neurologic exam, post-procedural infarct burden, 3-month functional outcomes, and treatment durability. Results: A total of 107 patients with symptomatic, angiographically confirmed cervical ICAO without tandem LVO were identified. Median admission NIHSS was 8 (IQR 11). Baseline radiographic stroke severity was assessed by ASPECT score (median 9; IQR 2), perfusion mismatch (present in 93%), and clinical-diffusion mismatch (42%). Median time from symptom onset to treatment was 25 hours (IQR 61). Successful revascularization was achieved in 92% of patients. At discharge, 83% had stable or improved NIHSS, while at 3-months 65% achieved functional independence (mRS ≤2). The most common complication was distal embolization (22%) of which 16% required intra-arterial treatment. Rate of significant restenosis (≥70%) was 15% at 1-year. Conclusions: Stenting in selected patients at risk of neurological deterioration due to symptomatic ICAO can be performed with high rates of technical success and good clinical outcomes. Because of significant peri-procedural risks and high rates of restenosis, randomized studies are necessary to understand the benefit of this approach." @default.
