We report the case of an 80-year-old hypertensive patient who suffered an ischemic stroke. He was asymptomatic, and clinical examination revealed blood pressure asymmetry with arterial hypertension in the left arm (BP = 170/94 mmHg) and arterial hypotension in the right arm (BP = 83/62 mmHg). Doppler ultrasound of the supra-aortic trunks showed an alteration of flow in the right subclavian artery. CT angiography revealed a retroesophageal course of the right subclavian artery with significant stenosis.
