Staged repair of truncus arteriosus with interrupted aortic arch: adjustable pulmonary artery banding.

Abstract

We report a successful two-stage treatment for an infant with truncus arteriosus with aortic arch interruption. The treatment consisted of flow-adjustable bilateral pulmonary artery banding using clipping and postoperative balloon dilation, followed by staged repair. The merits of this strategy are as follows: (1) bilateral pulmonary artery banding is less invasive than neonatal one-stage repair; (2) use of cardiopulmonary bypass can be avoided in the newborn period; and (3) control of pulmonary blood flow adjusted for body size is possible. Although further studies are needed, our therapeutic strategy might provide a clinically important option for managing severe congenital heart disease.
