Arteriovenous malformations (AVMs) are the most common cause of intracerebral hemorrhage in children. Different options exist for their successful management consisting of surgery, endovascular embolization, stereotactic radiosurgery, or a combination of these treatments. ⋯ In this paper, we discuss the different treatment modalities in the treatment of pediatric cerebral AVMs emphasizing the role of surgery and endovascular embolization as a preoperative strategy.

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.

We discuss the management of cerebral arteriovenous shunts in neonates, infants, and children, with emphasis on our experience with pediatric cerebral arteriovenous malformations (AVMs). The management of vein of Galen malformations is discussed in a separate chapter. ⋯ Careful clinical observation and timely intervention are important in the management of pediatric patients with intracranial arteriovenous shunts. Trans-arterial endovascular embolization with liquid embolic agents is the treatment of choice for safe stabilization and/or improvement of symptoms in the group of pediatric patients with intracranial arteriovenous malformations.

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.
