Duplication of the Left Vertebral Artery Origin: A Case Report

Abstract

Duplication of vertebral arteries is a very rare but clinically important condition. A duplicated vertebral artery origin can influence hemodynamics, pathogenesis of vascular lesions and treatment options. In cases of vertebral artery duplication, the vertebral arteries generally enter the transverse foramen higher up than normal. Awareness of these vertebral artery variants before procedures, such as neurointervention or surgery, may be beneficial. Here, we describe a case of a 51-year-old female patient with left vertebral artery duplication which was detected incidentally.
