[Surgical treatment and their long-term results of the ascending aortic lesions involving coronary arteries].

Seventeen patients underwent surgical treatment of the ascending aorta, aortic valve, and coronary artery as well. Diagnosis of 13 patients were annulo-aortic ectasia, 3 had dissecting aneurysm (type I: 2, type II: 1), and one had supra-valvular aortic stenosis. In annulo-aortic ectasia, Bentall's method was carried out in 11 cases, and Cabrol's operation was performed in 3, one of the latter group had received Bentall's procedure 4 years prior to the second operation. One patient died of acute myocardial infarction 3 days following operation, who had severe stenosis of the left anterior descending artery not detected by preoperative angiography. During long-term follow up, 2 patients died of cardiac failure. Three patients had dissection of the ascending aorta and coronary artery (right coronary artery: 2, left coronary artery: 1). The aorta was reconstructed, aortic valve was replaced, and coronary artery was revascularized with saphenous vein graft. They have been alive and well up to post operative 6 years. Right coronary ostioplasty as well as aortic valve replacement and extended aortoplasty were attempted in one patient with Williams' syndrome. This patient had been well until sudden death which occured 11 months after the operation.
