Median artery of the corpus callosum(MACC)refers to the median artery of the triplicate anterior cerebral artery(ACA). When MACC distributes to one or to both hemispheres, it is known as the accessory ACA. We performed detailed angiographic analysis of 32 consecutive patients operated upon for distal ACA(DACA)aneurysms, and noted that all DACA aneurysms occurring in the supracallosal portion were accompanied by an accessory ACA as vascular malformation. Such relationship between accessory ACA and DACA aneurysm in the supracallosal portion has not been previously reported.
胼胝体正中动脉（MACC）指的是三联大脑前动脉（ACA）的正中动脉。当MACC分布于一个或两个半球时，它被称为副ACA。我们对32例连续接受远端ACA（DACA）动脉瘤手术的患者进行了详细的血管造影分析，发现所有发生在胼胝体上方部分的DACA动脉瘤都伴有作为血管畸形的副ACA。胼胝体上方部分的副ACA与DACA动脉瘤之间的这种关系此前尚未见报道。
