From 1974 through 1983, 107 @entity1 4 days to 27 years old underwent 115 operations for treatment of @entity1498 . Thirty-two @entity1 were @entity1 (1 year old or younger), and 28 of them were newborns. All newborns were seen with @entity712 . Seventy-one @entity1 were seen with @entity101 . @entity154 were present in 72 @entity1 (67%). Resection was performed in 48 @entity1 , patch aortoplasty in 16, bypass of the coarcted segment in 15, and left subclavian @entity432 (LSAFA) in 36. Ligation of a patent ductus arteriosus was simultaneously performed in 28 @entity1 and pulmonary artery banding, in 4. Follow-up was 6 months to 9.2 years. There was a significant difference in aortic cross-clamp time between 26 @entity1 who had resection (37.9 +/- 12.9 minutes) (mean +/- standard deviation) and 32 @entity1 who had LSAFA (22.9 +/- 7.7 minutes) (p less than 0.05). Six @entity1 died within thirty days after operation; 5 of them had resection, and 1 had bypass. Major postoperative complications included @entity548 requiring exploration in 3 @entity1 (2 after resection and 1 after LSAFA) and @entity451 in 1 @entity1 after reoperation (resection) for recurrent @entity1498 3 years after patch aortoplasty. Paradoxical @entity101 was observed in 13 @entity1 , and sustained systemic postoperative @entity101 developed in 11 after effective repair of @entity1498 . There was no significant difference in early postoperative arm-leg pressure gradients between the types of operation or the various age groups.(ABSTRACT TRUNCATED AT 250 WORDS)
