[Interrupted aortic arch. A series of 15 patients].

Between 1983 and 1989, 15 children underwent surgical repair of interrupted aortic arch at 1 to 20 days of age. The anatomical form was a Celoria and Patton type B in all patients with an associated perimembranous ventricular septal defect in all but one who had multiple ventricular septal defects, and patent ductus arteriosus. Six children had a retro-esophageal right subclavian artery, two had subaortic stenosis and two had a right-sided descending thoracic aorta. In two children with severe hypoplasia of the ascending aorta the repair was performed in one stage with two deaths due to left ventricular failure. In the other B cases, a two-stage repair was carried out. The reconstruction of the aortic arch varied according to the individual case. All children had pulmonary artery banding. Seven children survived longer than 30 days. Six of them later underwent a complete repair. The only survivors were those patients in whom the neo-aortic arch grew harmoniously. The authors conclude that: a two-stage repair gave disappointing results in this series of consecutive patients, mainly because of the poor quality of the reconstruction of the aortic arch by thoracotomy.
