Mechanical Thrombectomy Using Retrievable Stents in Pediatric Acute Ischemic Stroke

ABSTRACT

Objectives: To report efficacy and outcome of mechanical thrombectomy for treatment ofpediatric acute ischemic stroke with large vessel occlusion using stent retrievers. Methods:Retrospective record review of institutional database for patients <18 years of age. Results:Five boys aged between 6 to 17 years received reperfusion therapy using mechanicalthrombectomy for acute ischemic stroke with large vessel occlusion (2 basilar, 2 middlecerebral 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 themodified Treatment In Cerebral Infarction scale (mTICI 3 or 2b) was achieved in all, usingstent retreivers. Favorable outcome as per the modified Rankin scale (mRS 0-1) wasachieved in all with no peri-procedural complications. Conclusions: Mechanicalthrombectomy using retrievable stents is a safe and effective therapy for pediatric ischemicstroke due to large vessel occlusion, and may be offered in carefully selected patients.
