A Novel Surgical Technique for Right-Sided Interrupted Aortic Arch by Interposition of a Pulmonary Autograft Tube.

Abstract

Right-sided interrupted aortic arch (IAA) is a rare cardiac anomaly. In general, the right bronchus sits higher than the left bronchus, so aortic arch reconstruction with a direct anastomosis has a risk of tracheal and bronchial obstruction. This report describes the successful definitive repair of a right-sided IAA in a 2.5-kg neonate by aortic arch reconstruction with a pulmonary autograft tube (PA tube). Postoperative three-dimensional multidetector computed tomography showed the reconstructed aortic arch without airway obstruction or aortic stenosis. The use of a PA tube is a simple and useful technique for aortic arch reconstruction in patients with a high risk of tracheal andbronchial obstruction, such as right-sided IAA.
