This anatomical observation was performed to investigate the aortic arch and their branches in Chinese water deer (Hydropotes inermis argyropus, Heude, 1884). The 18 carcasses of the Chinese water deer, ranging from about 0.9 to 17kg, were obtained from Kangwon‐Do Veterinary Service Laboratory in Chuncheon. The findings in the carcasses were based on the dissection and the silicon cast of the vessels made by retrograde injection into abdominal aorta. Only brachiocephalic trunk was branched from aortic arch in all carcasses. Brachiocephalic trunk gave off left subclavian artery, left common carotid artery, right common carotid artery, right costocervical trunk and right subclavian artery in 15 among 18 cases. Bicarotid artery, instead of separated carotid arteries, from brachiocephalic trunk was observed in only 3 male carcasses, in which have the different orders of internal thoracic artery and superficial cervical artery from subclavian arteries in both side. The left costocervical trunk were arose from left subclavian artery in all cases and gave off the highest intercostal artery, dorsal scapular artery, and deep cervical artery in order and continued as vertebral artery. The right costocervical trunk, from brachiocephalic trunk directly in all cases, were branched from at the same level in which right common carotid artery (or bicarotid artery) and right subclavian artery. The branching pattern was similar to that of the left. These results suggest that Chinese water deer in Korea has different branching pattern of brachiocephalic trunk with other hoofed domestic animals.
