[Primary repair of interrupted aortic arch in neonates].
In the Kardiocentrum, University Hospital Motol, Prague, protocol of the primary repair of interrupted aortic arch was introduced, and between 1993-1997, 15 neonates aged 1-26 days (median 5 days) were operated on. Treatment with prostaglandins E for maintenance of the ductal patency, correction of metabolic acidosis, and treatment of all complications were necessary before surgery. The correction was performed from the midline sternotomy approach, in extracorporeal circulation and deep hypothermia with circulatory arrest. Direct anastomosis between the ascending and the descending aorta was possible in all the patients. At the same time, associated heart lesions were corrected (ventricular septal defect in 13, persistent truncus arteriosus in 3, subaortic stenosis in 2, transposition of the great arteries, double-outlet right ventricle and aortico-pulmonary window in 1 patient, each). Four (26.7%) patients died after surgery. Out of the first 6 neonates 3 (50.0%) died, but out of the subsequent 9 patients only 1 (11.1%) died. Reoperation was necessary in 2 patients. All 11 early survivors are alive and doing well 8-54 months after the repair. In one of them restenosis at the site of aortic anastomosis and hemodynamically significant subaortic stenosis occurred. All the remaining patients have a nonrestrictive aortic anastomosis. Primary repair of interrupted aortic arch and associated heart lesions can be performed in a neonate with reasonable mortality. Treatment of complications is necessary before surgery. Results depend especially on the patient's clinical condition and experience of the center.
