Abstract
A 57 year old woman presented with dizziness and vertigo, and on physical examination was found to have asymmetric blood pressure in the upper extremities (80/50 mmHg on the left versus 150/80 mmHg on the right), as well as a decreased left radial pulse. She had a history of left lower extremity weakness, residual from a cerebrovascular accident in 2009. She was referred to interventional radiology (IR), after transfer from an outside hospital with left subclavian artery occlusion, noted on a CT angiogram of the chest.
