Abstract
Vein of Galen aneurysmal malformation (VGAM) is one of the most difficult intracranial vascular lesions because this disease consists of extremely high flow shunts and affects infants and small children. Thanks to the development of various diagnostic modalities, early diagnosis became possible allowing us to prepare appropriately according to the patients' general and neurological conditions. Recent improvements of endovascular techniques and materials enabled both transarterial and transvenous approaches even to the newborn infants, widening therapeutic windows. In this article, we discuss the selection of endovascular approaches based upon angioarchitecture of VGAM presenting four representative cases from our file.
