Abstract
Endovascular treatment (EVT) for large vessel, acute ischemic stroke in children remains a subject of debate, with evidence for its benefits derived from case series and individual case reports. At present, guidelines are cautious in recommending EVT for children under 5 years of age, mainly due to a lack of data and incomplete cerebral and femoral vessel development. However, based on the small number of cases reported in the literature, EVT appears to be safe and effective for pediatric use and arterial diameters can accommodate currently available devices. Available evidence shows that in patients with a normal arterial development, a 6-Fr femoral approach can be safely used by 2 years of age. We describe the case of a 2-year-old child who benefited from late-window EVT for a basilar occlusion. The procedure was safely performed using a 6-Fr femoral introducer, a 6-Fr guide catheter, and a 5-Fr aspiration catheter. We discuss also normal cerebral and femoral vessel development, providing descriptive tables of compatibility between femoral and cerebral arterial diameters by age groups and currently available endovascular devices.
