The Role of Anterior Translocation of Right Pulmonary Artery in the Correction of Aortic Arch Anomalies from the Midline

Abstract

Introduction: Dilated pulmonary artery can increase the postoperative airway complications after the simultaneous repair of aortic arch anomalies and cardiovascular lesions with large left to right shunt. It is claimed that the anterior translocation of pulmonary artery will reduce the airway compression. Case Presentation: Here we report 3 cases including an 11-month-old infant with ventricular septal defect (VSD) and coarctation, a 2-month-old infant with interrupted aortic arch (IAA) and VSD, and a neonate with aortopulmonary window (APW) in combination with coarctation in which all had a one stage repair of their lesions. Translocation of the right pulmonary artery (RPA) branch was performed in two patients, however with different postoperative courses that merit pondering over their fate. Conclusions: RPA anterior translocation could be considered as an additional palliation in some patients with coarctation repair from midsternotomy approach.
