RESUMO
From November, 1976, to June, 1983, 100 patients, 84 male and 16 female patients ranging in age from 13 to 74 years, were operated on for aortic insufficiency associated with an aneurysm of the ascending aorta. Twenty patients were in New York Heart Association Class I, 22 in Class II, 51 in Class III, and seven in Class IV. The surgical treatment in all cases consisted of total replacement of the ascending aorta with a tube graft containing a prosthetic aortic valve and reimplantation of the coronary arteries by an intermediate tube graft according to the technique already reported. In 68 patients an uncomplicated annulo-aortic ectasia existed, and in 32, an aortic dissection; nine of the latter group were operated on during the acute phase. The operative mortality for the entire group was 4% (four deaths). One patient has been lost to follow-up during a period ranging from 18 months to 8 years (average 54 months). The late mortality has been 11/96. Among the 84 survivors, clinical improvement is readily apparent (89% are in Class I or II). Twenty-five patients have been restudied by angiography, which revealed a satisfactory coronary and aortic appearance in all cases with neither stenosis nor aneurysm. The actuarial survival rate is 75% at 8 years. In conclusion, the treatment of aortic insufficiency associated with an aneurysm of the ascending aorta by insertion of a composite graft and reimplantation of the coronary arteries through an intermediate Dacron tube is a reliable method with low mortality and excellent long-term results.
