Moyamoya disease, a rare cause of pediatric stroke, is a cerebrovascular occlusive disorder resulting from progressive stenosis of the distal intracranial carotid arteries and their proximal branches. In response to brain ischemia, there is the development of basal collateral vessels, which give rise to the characteristic angiographic appearance of moyamoya. If left untreated, the disease can result in overwhelming permanent neurological and cognitive deficits. ⋯ The authors discuss the diagnosis and treatment of moyamoya disease in the pediatric population.

This study aims to analyze the clinical and radiological findings, timing and type of treatment, and outcome in children under 1 year of age that presented with neurosurgical vascular malformations. ⋯ In this neonatal age group (first year of life), we can find the whole range of neurosurgical vascular pathology: VGAM, AVM, cavernous malformation, DSM, pial AVF, DAVF, and sacular aneurysm. VGAM is the most frequent vascular malformation during the first year of age. The early treatment of vascular malformations prevents its adverse effects on a developing brain. A multidisciplinary team composed by endovascular and surgical specialists is necessary to discuss and treat each case.

Hemorrhage from an arteriovenous malformation (AVM) is the commonest cause of childhood stroke. Management options for children include observation and medical management, surgical resection, endovascular embolization, or stereotactic radiosurgery, alone or in combination. ⋯ Radiosurgery is the first and only biologic AVM therapy; it represents the beginnings of future cellular approaches to vascular malformation diseases. For this reason, the future of radiosurgery may be impacted positively by the development of other biologic strategies such as brain protection or endothelial sensitization.
