We report a 57-year-old male who suffered from ascending aortic aneurysmal dilatation complicated with acute localized dissection. He had received aortic valve replacement with a prosthesis for severe aortic regurgitation resulting from valve degeneration and annular dilatation 4 years previously at which time the maximal ascending aortic diameter had been 45mm so that a procedure for the aorta itself was not done. On the present occasion an aortogram showed a maximal aortic diameter of 90mm and localized dissection from above the right coronary ostium to near the connection to the brachiocephalic artery. A successful composite valve-graft replacement of the ascending aorta (Bentall procedure with Piehler's modification) was carried out on a semi-emergency basis. This experience with this case implies that certain intervention for associated moderate aortic dilatation should be considered when an aortic valve replacement is performed.
