The Bawean deer () is a small deer species endemic to the island of Bawean in Indonesia. The species is listed as critically endangered by the IUCN Red List. The current population is assessed to be less than 500 adults living in the wild. The cerebral arterial circle (also called the circle of Willis) is an anastomosis of arteries that supply the brain. The aim of this study was to describe the arterial vascularization of the brain in this species. Three different methods were used to obtain a complete arterial pattern of this region-latex injection, corrosion cast, and contrast-enhanced computed tomography. The arterial vascularization of the brain was described. The pattern of the arterial vessels supplying the brain in this species was similar to that described previously by ruminants. The vessel with the biggest lumen branching off from the circle of Willis was the medial cerebral artery. The basilar artery is a vessel with a narrow lumen and does not mediate the delivery of blood to the encephalon from the caudal side. The results of the study may be useful in creating veterinary protocols for treating vascular diseases in this species and further studies from the field of pathophysiology or pathology.
巴韦安鹿（）是一种仅分布于印度尼西亚巴韦安岛的小型鹿种。该物种被世界自然保护联盟红色名录列为极度濒危物种。据评估，目前野生成年个体数量不足500只。脑动脉环（也称为威利斯环）是供应大脑的动脉吻合。本研究的目的是描述该物种大脑的动脉血管分布。采用三种不同方法来获取该区域完整的动脉模式——乳胶注射、铸型腐蚀和增强CT造影。描述了大脑的动脉血管分布。该物种供应大脑的动脉血管模式与先前反刍动物所描述的相似。从威利斯环分支出来的管腔最大的血管是大脑中动脉。基底动脉管腔狭窄，不介导从尾侧将血液输送至脑。该研究结果可能有助于制定治疗该物种血管疾病的兽医方案，以及开展病理生理学或病理学领域的进一步研究。
