Conclusions about pediatric interventional neuroradiology • It deals with rare diseases that are mostly not treatable by a direct surgical approach. Results have been published that cannot be ignored today. • The traditionally poor prognosis of vascular disease in young children cannot justify isolated heroic procedures, just because the tools are easy to use and to purchase. • The low costs, clinical efficiency and low mortality-morbidity in cerebral intervention require a critical mass of patients per year. • In a given place standards of quality should be guaranted before settling on pediatric interventional neuroradiology and not after ward. • Although an interventional neuroradiologist is required for 5 million patients in the adult population, the vascular disease spread in pediatrics probably justifies European network coverage by a few centers to offer satisfactory training and the creation of new converging centers.
