Aberrant origin of the left vertebral artery: clinical case and scientific literature

Abstract

The variants in the origin of the trunks of the aortic arch are very heterogeneous. Among them, it is worth highlighting the variants that involve the origin of the vertebral artery and more specifically the left vertebral artery. We present the case of a 62-year-old patient in whom an aberrant vertebral artery was incidentally described in a computed tomography for oncological evaluation. This anatomical variant is asymptomatic in up to 5% of cases and can give rise to clinical problems of a vascular nature.
