ABSTRACT This article presents the results of analysis of the arterial vascular region of the Eurasian elk, which is a representative of the Cervidae family. The study was conducted on 39 Eurasian elks. The head arteries of 25 animals were filled with LBS 3040 synthetic latex. The head arteries of the other 14 Eurasian elks were filled with an acetone solution of stained chlorinated polyvinyl chloride and macerated. The arterial circle of the Eurasian elk's brain is composed of bilateral rostral cerebral arteries and caudal communicating arteries. The basilar artery closes the arterial circle caudally. The rostral cerebral artery first ramifies into the rostral choroidal artery, then, the middle cerebral artery and the rostral communicating artery. The caudal cerebral artery and the rostral cerebellar artery branch off the caudal communicating artery. The arterial pattern of the Eurasian elk's brain base is similar to the arteries found in other deer. Like in other Ruminantia, the rostral epidural rete mirabile is a unique structure in the Eurasian elk's arterial system. Anat Rec, 302:339–345, 2019. © 2018 Wiley Periodicals, Inc.
