title: Interruption of the aortic arch. Surgical considerations.
abstract: During a 10 year period, January, 1965, through January, 1975, 5 patients with interruption of the aortic arch (IAA) underwent operation at the Texas Heart Institute. The mortality rate was 60 per cent; 2 patients survived the operation. One 11-day-old infant with IAA, type A, a ventricular septal defect (VSD), and a patent ductus arteriosus (PDA) underwent successful two-stage treatment. A left subclavian-ductus anastomosis, closure of the PDA, and banding of the pulmonary artery were done initially. The VSD was closed later. The second survivor, a 3-year-old girl, had IAA, type B, with a PDA and VSD. Total correction was done with the aid of cardiopulmonary bypass and hypothermia. Considerations include palliative and staged procedures versus total correction with either conventional cardiopulmonary bypass or deep hypothermia and circulatory arrest. Survival rate is improved if associated lesions are totally repaired or palliated at the time of reconstruction of IAA.
