Thrombectomy using Zoom Reperfusion System in pediatric acute ischemic strokes: Case series and literature review.

ABSTRACT

INTRODUCTION: Zoom reperfusion system (Imperative Care, CA) has proven to be promising for use in adult mechanical thrombectomies (MTs) but has not been described in pediatrics. We present two cases of a 14-year-old with acute right middle cerebral artery (MCA) syndrome and a 10-year old with acute left MCA syndrome who underwent MT using Zoom Reperfusion System safely with TICI 2B and TICI 3 recanalization, respectively. METHOD: Case report and literature review. RESULTS: A 14-year-old healthy boy with right supraclinoid internal carotid artery (ICA) occlusion (case 1) and a 10-year-old boy with left hypoplastic heart syndrome and left ICA terminus occlusion (case 2) were taken for MT after receiving alteplase at our institution. Through femoral access, an 8-French sheath was introduced into the right femoral artery through which a Zoom 88 catheter was introduced and parked at the right petrous ICA segment in case 1 and left ophthalmic ICA segment in case 2. Angiogram demonstrated complete ICA occlusion just past the ophthalmic artery origin in case 1 and at the ICA terminus in case 2. Zoom system (88 and 71) was then navigated to the face of clot with vacuum manifold engaged with the clot. TICI 2B (with the help of Trevo stent retriever [Stryker]) and TICI 3 recanalization were achieved in cases 1 and 2, respectively. CONCLUSION: The use of Zoom reperfusion system could potentially be feasible for use in pediatric age group. Larger pediatric patient population is needed to establish its safety.
