Presentation
Difficulty ambulating with episodes of syncope.
Patient Data
Aberrant right vertebral artery arising from the aortic arch distal to the left subclavian artery. There is a conical outpouching at its origin suggesting a diverticulum. There is focal stenosis in the proximal left vertebral artery. Dominant left and hypoplastic right vertebral arteries.
Intimal flap in the left proximal subclavian artery suggesting dissection. Chronic. No evidence of extension into the left vertebral artery.
Case Discussion
Anomalous right vertebral artery arising from the arch of the aorta distal to the left subclavian and taking a retro-esophageal course. Patient presented with difficulty ambulating with episodes of syncope, likely unrelated to the finding.
