The patient was diagnosed as a case of expanding abdominal aortic aneurysm and annuloectasia of aorta due to Marfan syndrome. Abdominal aneurysm was located from 3 cm below the origin of left renal artery to left common iliac artery. Abdominal aneurysm was operated successfuly.

The size of abdominal aneurysm was about 28×15cm. The pathological findings of surgically removed abdominal aortic wall showed loss of elastic fibers and fragmentation of fibers in media.
