Point

・中大脳動脈は広範な脳の領域を灌流し，その障害は機能および生命予後に直結する．

・中大脳動脈は，脳主幹動脈閉塞症の最も好発部位である．

・血管解剖を理解することが手技の前提である．

　The middle cerebral artery divides into the cortical and perforating branches that supply blood to the extensive cerebral cortex and basal ganglia. In addition to an understanding of the normal vessel diameter and length, endovascular physicians should be familiar with anatomical variations. Understanding the perfusion territory is important for accurate diagnosis of the disease type.
