Abstract

Individual variability or variant anatomy is most common in blood vessels, among which brachiocephalic arteries should be distinguished. The article presents a case of the detection of one of these variations – an aberrant left vertebral artery branching off from the aortic arch in a 68-year-old patient. This artery was identified in him after a CT scan of the aortic arch and brachiocephalic arteries for pronounced vertebral-basilar insufficiency. In studying the angiogram, the authors carried out a morphometric analysis of all arteries branching off from the aortic arch.
