BACKGROUND The nonrecurrent inferior laryngeal nerve is an anomaly associated with the absence of the brachiocephalic artery (BCA) and the presence of arteria lusoria. METHODS The preoperative CT scans from 290 patients (9 nonrecurrent, 281 recurrent) were retrospectively reviewed. We identified the BCA or the arteria lusoria, and classified the relationship between the right subclavian arter...

The innominate artery (the right brachiocephalic artery) is an aortic branch. From this artery, right carotid artery and subclavian artery are bifurcated. This artery is short and relatively well protected by the bony thorax. However, injury of this artery is not uncommon. Several cases with innominate artery injuries have been documented involving blunt traumatic injury such as motor vehicle a...

Introduction The vertebral artery (VA) is important to posterior cerebral circulation. It arises from the superior surface of the first part of the subclavian artery medial to the scalenus anterior muscle. The vessel takes a vertical posterior course to enter into the transverse process of the sixth cervical vertebra. It continues through the transverse foramina of the cervical vertebrae and af...
