The present study was designed to provide a comprehensive analysis of the anatomical aspects of arterial blood vasculature in the water buffalo brains. Fifty cranial cavities of adult water buffaloes were opened via both the dorsal and ventral approaches and the arteries were exposed and photographed. The buffalo rostral epidural rete mirabile generally resembled that of large ruminants. The oculomotor, abducent and trigeminal nerves were intimately associated with the rostral rete. Similar to the majority of ruminants, the arterial circle of the brain was heart-shaped in buffalos and presented all collateral blood vessels as mentioned in the previous literature. The study further revealed that the cranial nerve roots were closely related to the arterial circle of the brain and could be used as indicators for differentiating various branches of the arterial circle of the brain. In addition to the usual variations of the arterial circle of the brain, a bihemispheric rostral cerebral artery along with an aplastic rostral cerebral artery were reported for the first time. The deviant behaviour of the rostral cerebral artery forms a baseline to study various clinical conditions of the blood vasculature in the buffalo brain. The rostral choroidal, middle cerebral and the caudal cerebral arteries constantly were emerged as single vessels without any variations. In conclusion, the anatomy of the arterial vasculature of the buffalo brain observed in the present study provided evidence of its morphological resemblance to other species of the Bovini tribe.
本研究旨在对水牛脑动脉血管解剖结构进行全面分析。通过背侧和腹侧入路打开 50 个成年水牛的颅腔，暴露并拍摄动脉。水牛颅硬膜网奇迹般地类似于大反刍动物。动眼神经、展神经和三叉神经与颅前硬膜网密切相关。与大多数反刍动物相似，水牛的脑动脉环呈心形，并呈现了之前文献中提到的所有侧支血管。研究还表明，颅神经根与脑动脉环密切相关，可作为区分脑动脉环各个分支的指标。除了常见的脑动脉环变异外，还首次报道了双侧额脑前动脉和无形成额脑前动脉。额脑前动脉的异常行为为研究水牛脑中血管的各种临床情况提供了基础。额脉络膜动脉、大脑中动脉和大脑后动脉始终作为单一血管出现，没有任何变异。总之，本研究观察到的水牛脑动脉血管解剖结构提供了其与 Bovini 族其他物种形态相似的证据。
