Vertebral artery partial duplication

Case contributed by Dr Lucía Aja

Presentation

Transient ischemic attack

Patient Data

Age: 68
Gender: Male

Two diferent origins for left vertebral artery are seen. One arises normally from left subclavian artery and the second arises from the aortic arch. Both vessels follow a parallel course before they link at V2 segment. Distal left vertebral artery follows a normal course to the vertebrovertebral junction.

Case Discussion

An anomalous vertebral artery origin from the aortic arch is the most frequent anatomic variant of the supra-aortic trunk origin.

Duplication (partial or complete) and fenestration of the vertebral artery are found rarely, probably representing persistence of embryonic plexiform vessels.
