Primary reconstruction of interrupted aortic arch--surgical management and results.
Type B interrupted aortic arch associated with other extracardiac and intracardiac congenital lesions is a lethal defect. Surgical management with a one- or two-stage approach is complex, difficult and associated with high morbidity and mortality. Between January 1996 and December 1999, 5 consecutive patients with type B interrupted aortic arch were operated on. The group included 3 girls and 2 boys weighing from 2.4 kg to 3.5 kg (mean 2.84 kg) and aged from 4 to 35 days (mean 15 days). All patients underwent a primary reconstruction of the aortic arch and one-stage repair of the associated heart defects. Two patients developed symptoms of mild aortic arch narrowing 7-12 months postoperatively. Balloon angioplasty of the obstructed site was successfully carried out in one of the patients. In the second child, angioplasty was not successful and surgery was used. All the patients survived and are being followed-up. This experience supports a strategy of primary one-stage repair of IAA type B, including direct anastomosis for aortic arch reconstruction, and all associated heart anomalies in the neonatal period.
