Pediatric arterial ischemic stroke is a rare but increasingly acknowledged disorder. Large vessel occlusions in this population have been treated off-label with endovascular thrombectomy. However, there is limited evidence to guide management. Small children, before the age of five when the cerebrovasculature reaches adult size, present additional challenges. We report the case of cardioembolic basilar occlusion in a two-year-old and the technical details of endovascular management, currently lacking in published literature. We employed a 5 French slender sheath, typically used for radial access, as a femoral short sheath. We accessed the dominant vertebral artery with a 5 French intermediate catheter, navigated with a typical 0.027-inch microcatheter and 0.014-inch microwire, and performed direct aspiration thrombectomy of the basilar clot. No closure device was employed. The patient had a near-complete and durable recovery. Small children present additional challenges for the endovascular management of stroke. Pre-procedural imaging can be used to design an aspiration-capable system appropriate for the child's size. Endovascular thrombectomy in children is feasible with some modifications to adult protocols.
