[Surgical management of aortic coarctation in the newborn infant]

Between 1978 and 1983, 35 neonates with coarctation of the aorta (from a group of 200 cases with the same pathology) underwent coarctation relief. Indications for operation were persistent heart failure and/or hypertension. Three surgical techniques were employed: Aortoplasty with prosthetic patch (politetrafluoroethylen) in 23 cases. Repair with subclavian flap in 11 cases, and resection of coarctate segment with and-to-end anastomosis in only one case. It is an important fact the high incidence of congenital cardiac malformations associated with coarctation of the aorta in neonates. There were 8 deaths (six of them with associated cardiac malformations, and other with miocardiophaty). There were 8 late deaths and 5 cases with restenosis, and no hypertension cases. All others are well in the follow-up. Some of them are waiting for definitive correction of their major cardiac malformation. The high risk of mortality in this group, mark again the importance of adequate medical treatment previous to surgical correction in optimal conditions and as early as possible.
