Abstract: Clinically persistent atrial fibrillation (AF) occurring with systemic embolism is not uncommon.In contrast,the incidence of embolism due to paroxysmal AF is far lower than that of persistent AF.[1] Cerebral arteries are the most common sites of emboli caused by AF,followed by the mesenteric artery,splenic artery,lower extremity arteries,and renal arteries.However,the occurrence of concurrent bilateral renal artery emboli is extremely rare in paroxysmal AF patients.Within the scope of the information,we have collected,only three similar cases have been reported.
