Surgical treatment of aneurysms of the ascending aorta.
From January 1970 to April 1975, 132 patients underwent surgical repair of aneurysms of the ascending aorta at this institution, 24 of whom had acute dissections. In almost all cases the ascending aorta was replaced with a Dacron tube graft. Aortic valve replacement was performed in 100 patients and 23 patients underwent coronary artery revision or bypass. Fifteen hospital deaths occurred. Although chronic or nondissecting aneurysms may be dealt with on an elective basis, acute dissections require prompt surgical intervention. Symptomatology and radiographic findings are such that angiography may not be necessary to establish the diagnosis. Clinical evidence of aortic regurgitation in an acute dissecting aneurysm is sufficient indication for immediate operation. Improvements in surgical techniques, fabric grafts, and valve prostheses have all contributed to the successful surgical treatment of aneurysms of the ascending aorta.
