Interrupted aortic arch operation in the first week of life: hemodynamic and angiographic evaluation one year later.

Operation for interrupted aortic arch (IAA) was successful in 2 infants during the first week of life. Both had postoperative hemodynamic and angiographic evaluation at one year of age. The first infant had a type A IAA, and prostaglandins were infused to prevent ductal closure prior to the insertion of a graft between the two ends of the interrupted aorta. The second infant had a palliative operation for type B IAA (pulmonary artery banding and graft from main pulmonary artery to descending aorta). These patients represent the ninth and tenth successful operations for IAA in this age group and are reported with long-term reevaluation.
