Vein of Galen Aneurysmal Malformation: An Updated Review

Abstract

AbstractVein of Galen aneurysmal malformation (VGAM) is a rare intracranial vascular anomaly in the choroidal arteries characterized by the persistence of the embryonic median prosencephalic vein of Markowski (MProsV). It is common in children with high mortality and disability rates. VGAM-associated clinical presentations include heart failure, hydrocephalus, and neurological symptoms, which make it difficult for diagnosis. Simultaneously, the complex VGAM vascular architecture, characterized by a wide interindividual variability, makes the management of this condition challenging to clinicians. Thus, timely diagnosis and treatment of VGAM are crucial. In this review article, we elucidated the latest research progresses of VGAM in the aspects of the pathogenesis, classification, clinical features, imaging, management, and prognosis based on recent relevant literatures. It is beneficial to raise the awareness of VGAM and improve the level of management and treatment.
