[Surgical treatment of aortic root aneurysm associating with infectious endocarditis].

From 1979 to 1989, aortic root aneurysms were encountered in 6 of the 30 patients who underwent surgical treatment for infectious endocarditis. Four patients underwent aortic valve replacement and direct or patch closure of the orifice of aortic root aneurysm. In additional 2 patients with infected aneurysm of right coronary sinus of Valsalva rupturing into the right ventricle, the aneurysm and infected tissue in the right ventricular outflow tract were completely resected and the defect of aortic sinus and VSD were closed with double Teflon fabric patches. All patients survived postoperatively, however, one patients died 1.5 months after the operation probably due to rupture of mycotic aneurysm of cerebral artery. Another late death seemed to be concerned with recurrent aortic root aneurysm, in which case direct closure of aneurysm had been performed. We believe that even if the aneurysm seems to be small, its orifice should be closed with the use of a fabric patch to prevent recurrent aneurysm formation.
