    Abstract:
    BACKGROUND: Many children and young adults have undergone surgery for coarctation of the aorta. Individual surgical techniques employed in the treatment of patients and their effects on incidence of recoarctation were reviewed. METHODS AND DATA: Over the last ten years, a total of 201 cases of aortic coarctation were surgically treated at our department. The three forms of coarctation of the aorta recognized by the Society for Cardiothoracic Surgeons namely: isolated coarctation, coarctation with ventricular septal defects and coarctation with complex cardiac anomalies, were represented. RESULTS: 19 cases of recoarctation were recorded over the period of follow-up, representing 10% of all operated patients. On univariate analysis, the risk of recoarctation was closely linked with the following variables: use of resection and end-to-end anastomosis (p=0.01), age at operation less than one month (p=0.0002) and weight at operation less than 3 kg (p=0.01). The risk of recoarctation was found to be highest when resection and end-to-end anastomosis was employed in neonates (p<0.0001). Most cases of recoarctation as shown by the Kaplan-Meier plot occurred within the first year after surgery. CONCLUSION: The use of simple resection and end-to-end anastomosis in neonates is associated with a high risk of recoarctation. Hence, our preferred surgical technique in neonates is the extended resection and end-to-end anastomosis, which is associated with a considerably lower risk of recoarctation in this age group.
