Abstract

An anomalous artery directly connecting the common carotid artery and internal carotid artery was discovered on the right side in the cadaver of an 83-year-old Japanese female, and the facial artery, maxillary artery, and superficial temporal artery arose from the common carotid artery by a common trunk. The anomalous artery arose from the posterior aspect of the common carotid artery at the level of the origin of the superior thyroid artery, and joined the posterior aspect of the internal carotid artery. The anomalous artery was covered by the connective tissue surrounding the common carotid artery and the internal carotid artery. The anomalous anastomosis, especially the proximal portion, may have arisen from the second branchial arch artery during development.
