As part of a study of the microsurgical anatomy of the pericallosal artery, we describe one brain with three unusual anatomical variants.
From the autopsy of a 45 year-old female, we extracted the brain and all the arterial blood vessels were washed off with saline solution to be injected afterwards with red latex. The brain was then immersed in 10% formalin for two months. Finally, we dissected and measured the internal carotid artery segments, using a digital Vernier caliper under a Carl Zeiss OPMI surgical microscope with magnification of 6x up to 40x.
The brain's weight was 1250 grams and three rare anatomical variants were found: 1) right accessory middle cerebral artery (ACMA-d), 2) right bihemispheric anterior cerebral artery (ACABihem-d), 3) median artery of the corpus callosum (AMCC).
The association of the anatomical variations described previously is inconstant; furthermore, their appearance in a single case is rare.
作为胼周动脉显微外科解剖学研究的一部分，我们描述了一例具有三种罕见解剖变异的大脑。
从一名45岁女性的尸检中取出大脑，用盐溶液冲洗掉所有动脉血管，随后注入红色乳胶。然后将大脑浸入10%福尔马林中两个月。最后，在卡尔·蔡司OPMI手术显微镜下，使用数字游标卡尺对颈内动脉各段进行解剖和测量，放大倍数为6倍至40倍。
大脑重量为1250克，发现了三种罕见的解剖变异：1）右侧副大脑中动脉（ACMA-d），2）右侧双半球大脑前动脉（ACABihem-d），3）胼胝体正中动脉（AMCC）。
先前描述的解剖变异之间的关联并不恒定；此外，它们在单个病例中出现的情况很少见。
