Mechanical Thrombectomy Using Retrievable Stents in Pediatric Acute Ischemic Stroke

Abstract

To report efficacy and outcome of mechanical thrombectomy for treatment of pediatric acute ischemic stroke with large vessel occlusion using stent retrievers. Retrospective record review of institutional database for patients <18 years of age. Five boys aged between 6 to 17 years received reperfusion therapy using mechanical thrombectomy for acute ischemic stroke with large vessel occlusion (2 basilar, 2 middle cerebral and 1 internal carotid artery). Pediatric National Institute of Health Stroke Scale (PedNIHSS) at onset ranged from 12 to 21. Complete recanalization as defined by the modified Treatment In Cerebral Infarction scale (mTICI 3 or 2b) was achieved in all, using stent retreivers. Favorable outcome as per the modified Rankin scale (mRS 0-1) was achieved in all with no peri-procedural complications. Mechanical thrombectomy using retrievable stents is a safe and effective therapy for pediatric ischemic stroke due to large vessel occlusion, and may be offered in carefully selected patients.
