概要

A 72-year-old man was admitted to our hospital with a renal infarction. On admission, computed tomography (CT) of the abdomen revealed total occlusion of the right renal artery, which was found to be recanalized with residual thrombus 7 days later. Transesophageal echocardiography and chest CT demonstrated crescent-shaped thrombus in the non-coronary sinus of Valsalva without evidence of aneurysm. After coumadin treatment the patient did not experience recurrent episodes of systemic embolization. Five months after the initiation of anticoagulation, transesophageal echocardiography and chest CT demonstrated disappearance of the thrombus. This is a rare case of renal infarction caused by a thrombus in the non-coronary sinus of Valsalva without aneurysm.
