Growth potential in the new aortic arch after non-end-to-end repair of aortic arch interruption in infancy.
BACKGROUND
Complete repair of infants with interrupted arch and ventricular septal defect through a midline incision has been the preferred method for more than 20 years. End-to-end anastomosis can result in restenosis if there is excess tension. Two methods of reducing this tension have been described, and the subsequent growth of the new aortic arch is demonstrated.


METHODS
In 2 infants (5 and 9 months old) the duct was used to create a new aortic arch. In 3 other younger infants the left carotid artery was divided, turned down, and anastomosed to the descending aorta to form the new arch. These operations were performed through the midline at the same time as the ventricular septal defect was closed.


RESULTS
All 5 patients are well now 8 to 19 years postoperatively. One patient required reoperation for stenosis at the anastomotic site, but all have subsequently shown good growth on follow-up angiographic and magnetic resonance imaging studies.


CONCLUSIONS
Although end-to-end repair is best, these alternative methods have shown very satisfactory aortic growth into adult life.
