A comprehensive study on the arterial vasculature of the brain in water buffalo (Bubalus bubalis): Clinical correlates

Abstract

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.

Comprehensive analysis of the rostral and caudal cerebral artery branching patterns in the dromedary camel (Camelus dromedarius)

“…Kiełtyka-Kurc et al ( 4 ) reported similar results in Bactrian camels. According to John et al ( 27 ), in buffalo, the RCA was observed to split into two to three branches at the anterodorsal aspect of the medial surface of the frontal lobe. Our study revealed that the rostral cerebral artery sends several cortical branches to the medial surface of the frontal and parietal lobes.…”

“…The caudal branch supplied the posterior and inferior aspects of the occipital lobe. While the rostral branches supplied the caudomedial area of the occipital lobe ( 27 ). The same observation has been made in humans, showing that several cortical branches originate from the posterior cerebral artery, including the anterior temporal, posterior temporal, medial occipital, and lateral occipital arteries ( 57 ).…”
