Rapid renal function deterioration: an unusual presentation of coral reef plaque.

Coral reef aorta is an uncommon variant of atherosclerotic disease. We report a rare presentation of rapid renal function deterioration in a patient with coral reef plaque protruding into the renal orifices without significant disease elsewhere. The patient was successfully treated with aorta endarterectomy, resulting in complete resolution of renal dysfunction. This case highlights the importance of prompt intervention for renal rescue.
