  • Title: [Mid-term results of treatment of aortic coarctation in neonates].

    Abstract:
    Between 1990 and 1997, 122 neonates aged 8.7 +/- 7.5 days, 75 boys (61.4%), were referred for coarctation of the aorta which was isolated (54 cases) or associated with one (52 cases) or more (20 cases) ventricular septal defects. Hypoplasia of the aortic arch, diagnosed in 52 cases, was more common in children with ventricular septal defects (p < 0.05). The diagnosis was later in isolated coarctation (10.6 +/- 6.8 days) than in cases with shunts (7.8 +/- 7.7 days) and/or hypoplasia of the aortic arch (5.1 +/- 4.3 days). One hundred and nineteen patients were operated, including 112 of left thoracotomy (24 had pulmonary artery banding in addition) at the age of 1.1 +/- 2.7 months, and 7 by sternotomy of first intention for aortic repair and closure of ventricular septal defect. After thoracotomy, closure of the ventricular septal defect was undertaken at 11.3 +/- 10.8 months in children who had undergone previous pulmonary banding and at 3.5 +/- 2.4 months in the absence of banding. Early mortality after aortic repair was 2.5% and late mortality 9.5%, higher in cases of large ventricular septal defects and hypoplasia of the aortic arch (p < 0.001). Follow-up varied from 55 days to 7.8 years (3.99 +/- 2.24 years). Global survival was 97.5% at 1 month and 98.2% at 8 years. In coarctation with ventricular septal defect survival was 95.6% at 1 month and 74.7% at 8 years with a worse prognosis in cases with large single interventricular shunts. Restenosis was observed in 28.5% of cases, 2.25 +/- 3.8 months after aortic surgery (88.5% of cases before the 6th month) and was generally treated by percutaneous aortic angioplasty (10 cases performed 13.5 +/- 12 months after surgery). In all, two factors seemed to increase the risk of death (hypoplasia of the aortic arch and large ventricular septal defects) and restenosis was observed in 1 out of 4 cases, usually before the 6th postoperative month.
