Background:
This report deal with our surgical experience at PSCC in neonatal aortic arch obstruction (369) cases.

Methods:
729 Cases underwent Coarctation or Interrupted Arch repair at PSCC, in the Period between Oct.1982 to Dec 2006. only cases < 3months of age were reviewed. 369 were neonate and small infants < 3months, median age was 16 days.
Male to Female ratio for COA 1:1.5. Male to Female ratio for IAA 0.9:1
Weight is 1.5 to 4.7 kg, median weight is 2.6kg . Associated cardiac problems were detected in 232cases(62.8%).VSD’s 133(36%), Single Ventricle were 17cases(4.6%). Complex lesions were 58 cases (15.7%), One case of complete congenital heart block.
Result:
Extended arch repair were done in 140 pts (38%) . 111 pts(30%) had resection and end to end at anastomosis. 118 pts(32%) had Subclavian flap. Hospital Mortality were 17 cases (4.6%), 11 COA (3.5%), 6 IAA. (11%). Operative complications: Immediate – post operative 24-36 hrs, hypertension were noted in 117(32%), NEC 41 cases, 2 case had paraplegia, Hemorrhage need re-exploration in 4 cases, Chylothorax 21 cases, Diaphragmatic palsy 7 cases, Hoarseness of voice was noted in 3 cases, Periapism in one case. Re-coarctation that needed intervention occurs in 23 cases (6.2%). Recoarctation is related to BW <3 Kg (P value 0.04), and not to Type of Surgery (p value = 0.30).
Conclusion:
Surgery For Aortic Arch Obst. Is safe reproducible with low mortality and recoarctation rate. Recoarctation is related to BW., and Surgical experience and not to the Type of Surgery.
