Modified extended end-to-end repair of coarctation in neonates and infants

Abstract

Although the classic extended end-to-end repair is the procedure of choice in most neonates and infants with coarctation of the aorta, there is a problem of distance despite extensive mobilization and impairment of growth of the arch because of scarring in some patients. Since December 1999, 15 neonates and infants without significant arch hypoplasia have undergone a modified extended end-to-end repair of coarctation of the aorta at our institution. The anastomosis was performed between the posterior wall of the isthmus and base of the subclavian artery and anterior wall of the descending aorta, resulting in an anastomosis that was usually 1(1/2) times the diameter of the descending aorta. All patients survived and were followed up to 57 months (average, 34). Two patients developed significant gradients 3 months and 1 year postoperatively, respectively, probably from luxurious tissue growth at the suture line. Both were treated successfully with balloon dilatation. The modified extended end-to-end repair provides another option for repair of coarctation in neonates and infants. It requires less mobilization of the arch and descending aorta. It is particularly useful in patients with long isthmus.
