Bovine arch with thyroidea ima artery


Aortic arch variants are common, occurring in ~30% of the population. Bovine arches are present in about 15% of the population. In the setting of potential neurointervention (e.g. for treatment of aneurysms or vasospasm) recognition of these are important because variant anatomy can complicate access to the carotid or vertebral arteries.
