An unpaired trunk forming part of the anterior cerebral arteries, the so-called azygos pericallosal artery, was found in a male fetus among a collection of 200 fetuses. The morphological characteristics of the trunk and the anterior cerebral arteries at the "preazygos" and the "postazygos" segments were examined using an operating microscope. The azygos pericallosal artery distributes into three postazygos segments of which only the median postazygos segment or median callosal artery had a bihemispheric distribution of its branches to the medial telencephalic surfaces.
在200例胎儿标本中，发现1例男性胎儿存在一条不成对的干，它构成大脑前动脉的一部分，即所谓的奇静脉胼周动脉。使用手术显微镜检查了该干以及“奇静脉前”和“奇静脉后”段大脑前动脉的形态特征。奇静脉胼周动脉分为三个奇静脉后段，其中只有中间奇静脉后段或中间胼周动脉的分支向内侧端脑表面呈双侧半球分布。
