Duplication of the vertebral artery: A series of four cases
Keyword(s):
Introduction Duplication of the vertebral artery (VA) is a rare vascular variant, with less than 50 reported cases in the literature. Case series We present four cases of VA duplication and discuss the imaging findings, which highlight the rarely seen VA duplication. Discussion VA duplication is generally considered to be an incidental finding. The VA is formed from the fusion of the longitudinal anastomoses that link the cervical intersegmental arteries, during the 32–40-day stage. The duplication of the VA is a clinically relevant finding for planning of head and neck surgery and neuro-interventional procedures.
