[Anomalous case of the left common carotid artery arising from the brachiocephalic trunk]

We found an anomalous branch of the aortic arch during the students' dissection practice at Fukuoka Dental College in 1988. The results are as follows; This case was found in a 92-year-old female cadaver (cause of death: cardiac dissufficiency), whose brachiocephalic trunk arose from the aortic arch forming a striking trunk with the left common carotid artery. The diameter of this trunk was 17.2 mm at its origin and the longitudinal length was 11.0 mm. This case corresponded to Typus B of Adachi's classification, while to Type C of De Garis's.
