BARBERO-MARCIAL, Miguel et al. Technique for correction of truncus arteriosus type I and II without extracardiac conduits. Rev Bras Cir Cardiovasc [online]. 1989, vol.4, n.1, pp.1-8. ISSN 0102-7638. http://dx.doi.org/10.1590/S0102-76381989000100001.
A new corrective surgery for truncus arteriosus (TA) without the use of extracardiac conduit was employed in 7 patients with truncus (TA) type I in 6 cases and type II in 1 case, aged from two to nine months. The common TA was septated with a patch into aortic and pulmonary segments and the ventricular septal defect was closed through ventriculotomy; a direct anastomosis between the pulmonary arteries and the right ventricle was performed, the anterior wall of this, being contructed with a patch with a monocusp valve. There was one imediate postoperative death. In the surviving six patients the RV/LV postoperative peak systolic was less than 0.51 in five and 0.60 in one with residual VSD; all are in functional class I, in postoperative period between one and fourteen months. Based in these results we propose this technique for patients with type I or II, in the first year of life.
