JATENE, Marcelo B; JATENE, Fábio B; AULER JUNIOR, José Otávio C and JATENE, Adib D. Surgical treatment of annuloaortic ectasia with aortic valve preservation. Rev Bras Cir Cardiovasc [online]. 1991, vol.6, n.3, pp.174-181. ISSN 0102-7638. http://dx.doi.org/10.1590/S0102-76381991000300006.
The substitution by synthetic graft and aortic valve replacement is the commonest treatment of AE. The aortic valve replacement generally occurs due to aortic insufficiency caused by aortic annulus dilatation; a mechanical prosthesis Is generally used. The authors present two male patients (34 and 62 y.) operated on for treatment of AE. The first had Marfan Syndrome and associated chronic aortic dissection. The surgical technique used was the substitution of the ascending aorta by a Dacron double velour graft. The pathologic aortic wall was excised, preserving the aortic valve. The tube was implanted externally to the valve and fixed bellow the aortic annulus and the aortic valve was suspended and fixed internally in the tube. The coronary ostia were then implanted in the graft. Both patients had good postoperative evolution being asymptomatic and with no aortic insufficiency after a post-operative period of 5 and 7 months. This technique could be used as an option for the treatment of AE with the advantage of aortic valve preservation.
