This report describes an anomaly of the right subclavian artery arising from the aortic as the last branch, which was found in a female cadaver (76 years old) during a dissection practice class for students at Fukuoka Dental College in 1990. From the aortic arch with a nomal course the following branches arose in turn. The bicarotid trunk, the left subclavian artery and the right subclavian artery as the last branch. The right subclavian artery arose from the postero-superior wall of the aortic arch, and bents sharply to the right, it ran transversally behind the esophagus and caused depression on the dorsal wall of the esophagus. This case belongs to type G by Adachis' and to type H by Williams-Nakagawa classification, while to type 2 by Holzapfel and to type E by the De Garis classification. The right recurrent laryngeal nerve dose not make the loop under the right subclavian artery. The incidence of this anomaly dissected at Fukuoka Dental College was 0.2%.
