Vein of Galen aneurysms may be defined as direct arteriovenous fistulas between choroidal and/or quadrigeminal arteries and an overlying single median venous sac. Anatomic analysis of 23 cases of vein of Galen aneurysm and correlation with known embryologic data indicate that the venous sac most probably represents persistence of the embryonic median prosencephalic vein of Markowski, not the vein of Galen, per se. The frequent concurrent venous abnormalities are easily understood as (a) retention of fetal anatomical features and (b) frequent occlusions of the dural sinuses of the posterior fossa, especially the sigmoid sinuses.
大脑大静脉动脉瘤可定义为脉络膜动脉和/或四叠体动脉与上方单一的正中静脉囊之间的直接动静脉瘘。对23例大脑大静脉动脉瘤的解剖分析及其与已知胚胎学数据的相关性表明，静脉囊很可能代表马尔科夫斯基胚胎前脑正中静脉的残留，而非大脑大静脉本身。常见的并发静脉异常很容易理解为：（a）胎儿解剖特征的保留；（b）后颅窝硬脑膜窦，尤其是乙状窦的频繁闭塞。
