Staged repair of truncus arteriosus with double aortic arch, tracheoesophageal fistula, and choanal atresia via a multidisciplinary approach: A case report

Research output: Contribution to journalArticlepeer-review

Abstract

The previously unreported case of a child with an exceedingly rare amalgamation of complex defects, including truncus arteriosus (TA), double aortic arch (DAA), tracheoesophageal fistula, and choanal atresia is presented. First, on day-of-life (DOL) 2, with a joint effort involving Pediatric Cardiac Surgery, General Surgery, and Otolaryngology, division of tracheoesophageal fistula and repair of esophageal atresia, along with choanal atresia repair, was carried out. Via a right thoracotomy, the tracheoesophageal fistula, located medial to the azygous vein, was skeletonized and ligated. The proximal esophagus was then mobilized up to the thoracic inlet as it coursed through the vascular ring. This enabled esophageal anastomosis with preservation of both aortas. Next, on DOL 11, the child underwent TA repair. Following a standard midline sternotomy and cooling to moderate hypothermia, the left aortic arch was divided and oversewn. The aorta was then transected anteriorly, and the main pulmonary artery (MPA) exiting the posterior aorta was harvested as a single button. The aortic defect from the pulmonary artery button was repaired with autologous pericardium. Next, through a right ventriculotomy, the previously seen conoventricular septal defect was identified and closed. Finally, a 10-mm pulmonary homograft was anastomosed to the pulmonary artery bifurcation to complete the repair. The patient was discharged on DOL 78 and was noted to be doing well at 1-year follow-up. This case validates the feasibility of fistula repair complicated by DAA through a right thoracotomy, the durability of staged, complete repair of TA and DAA, and the advantages of a holistic, team-based approach that optimizes timing of all repairs based upon a careful consideration of the exponential, rather than additive, effects of multi-organ disease on post-cardiac surgery outcomes in neonates.
