[A case report of type II dissecting aneurysm after aortic valve replacement, successful repair by the modified Cabrol's method].

A case of type II dissecting aneurysm after aortic valve replacement was reported. The patient was a 66-year-old man, who was diagnosed as III degree aortic valve regurgitation without aortic dilatation, and performed aortic valve replacement with a 27A Omniscience prosthesis. Postoperative course was very smooth for 7 years, however he was admitted to our hospital of the sudden anterior chest pain. Computed tomography and aortography revealed marked dilatation and dissection of ascending aorta and occlusion of the right coronary artery. The operation of the modified Cabrol's method was performed, and he is well alive one and half a year after operation. Dissecting aneurysm in the late term after aortic valve replacement is rare, and its prognosis and re-operative results are very poor.
