The anatomy of the abnormal left vertebral arteries was studied. During routine dissection by dental students at Fukuoka Dental College, 162 human cadavers were used as experimental subjects. These abnormalities could be classified into three groups (type C, type D and type K) according to the classifications by Adachi, Williams and Nakagawa, and the incidence of each type in our cases was compared with that in these previous reports. In type C the aortic arch gave off the brachiocephalic trunk, the left common carotid artery, the left vertebral artery (origin directly from the aortic arch) and the left subclavian artery. This type was found in five (3.08%) case. In type D, the aortic arch gave off the bicarotid trunk, left vertebral artery (origin directly from the aortic arch) and the left subclavian artery. This type was found in one (0.62%) case. In type K, the aortic arch gave off the brachiocepalic trunk, the left common carotid artery and the left subclavian artery. The left vertebral artery arises from the proximal part of the portion of the left subclavian near the aorta. This type was found in one (0.62%) case.
