Persistent embryological carotid-basilar anastomoses are rare. There has been no report on persistent anastomosis between the accessory meningeal artery and the antero-superior cerebellar artery. We describe a 3-year-old boy with moyamoya disease manifesting such a congenital vascular anomaly, namely, a large anastomosis between the accessory meningeal artery and the antero-superior cerebellar artery associated with marked hypoplasia of the basilar artery. This persistent vascular anomaly is considered embryologically as an additional variant of the persistent primitive trigeminal artery, i.e., a "stapedo-trigemino-cerebellar" variant.
持续性胚胎期颈基底吻合极为罕见。目前尚无关于脑膜副动脉与小脑前上动脉之间持续性吻合的报道。我们描述了一名患有烟雾病的3岁男孩，其表现出这种先天性血管异常，即脑膜副动脉与小脑前上动脉之间存在一个大的吻合，并伴有基底动脉明显发育不全。这种持续性血管异常在胚胎学上被认为是持续性原始三叉动脉的一种额外变异，即“镫骨-三叉-小脑”变异。
