Transbrachial Carotid Artery Stenting Can Prevent Renal Cholesterol Embolism

A 78-year-old man was admitted for the treatment of internal carotid artery stenosis. The left internal carotid artery was occluded and stenosis of the right internal carotid artery was progressive. The patient had a history of renal cholesterol embolism associated with percutaneous peripheral intervention. Stenting of the right internal carotid artery was successfully performed via the right brachial artery, and cholesterol embolism was not noted after the procedure. This case suggests that carotid artery stenting (CAS) performed via a brachial approach is less likely to elicit cholesterol embolism than CAS performed via a femoral approach.
