Various branching patterns of the aortic arch in the Siberian roe deer (Capreolus pygargus, Pallas, 1771) on Jeju Island

抄録

This study examined and compared the branching pattern of the aortic arch (AA) and its major branches in the Siberian roe deer (Capreolus pygargus) on Jeju Island (Jeju roe deer [JRD]) with those in the roe deer of the Korean peninsula (mainland roe deer [MRD]). Seven of the nine expected types was observed in the arterial silicone casts of 29 deer (10 males, 19 females). The JRD was identical to the MRD in that absence of the typical pattern; however, the main three pattern types differed between the two. This difference resulted from differences in the branching patterns of the right subclavian artery and costocervical trunk. In conclusion, the JRD has different type of AA from the MRD.
