A 22-year-old man was found on routine physical examination to have a bruit, loudest to the right of the manubrium. Magnetic resonance angiogram (MRA) showed a proximal right subclavian artery aneurysm. The only relevant history was a minor motor vehicle accident 4 years before.
A left anterior oblique view of the pre-operative angiogram shows the location of the fusiform aneurysm between the brachiocephalic bifurcation and the takeoff of the right vertebral artery (see neck anatomy).
