Rule of 5: angiographic diameters of cervicocerebral arteries in children and compatibility with adult neurointerventional devices

Abstract

The growth curve of the cervicocerebral vasculature displays rapid growth until age 5, at which point most children's vessels are nearly adult size. By age 5, most neuroendovascular devices are size-compatible, including thrombectomy devices for stroke. Under 5 years of age, some devices might still be compatible.
