title: An unusual case of bilateral coronary artery aneurysms and aortic aneurysms complicated by stenotic lesions.
abstract: A 71-year-old Japanese woman presented with a chief complaint of throbbing sensations in the abdomen. When she was 16 years old, she was exposed to atomic radiation since she was 1.2 km away from the drop zone of the Nagasaki atomic bomb. Abdominal CT performed at the age of 61 revealed the presence of localized calcification below the renal artery, together with abdominal aortic aneurysms measuring 4.9 cm in maximum diameter. Since the abdominal aortic aneurysms enlarged in May 2000, the patient was admitted to our department for further examinations and treatment on July 7. Although the patient did not complain of thoracic symptoms, cardiac catheterization revealed the presence of multiple coronary artery aneurysms and severe stenosis in the main trunk of the left coronary artery and proximal regions of the right coronary artery, together with a complicated collateral circulation course. Coronary artery aneurysms were localized similar to the abdominal aortic aneurysms, and were complicated by severe calcification and obstructive lesions. Coronary arterial bypass grafting was performed after the severity of the coronary artery aneurysms was morphologically evaluated. The course of the abdominal aortic aneurysms was followed without surgical treatment. Although the etiology of the aneurysm formation in this patient was investigated, it remained unclear.
