Surgical management of coarctation of aorta.

Between 1961 and 1988, 68 patients underwent operation for coarctation of the aorta. The average age of presentation of these subjects was higher than in other series. 7.1 percent were asymptomatic, a finding which is not seen in reports from the west. Operative procedures included resection and end to end anastomosis, resection and graft interposition, bypass grafting, patch aortoplasty and subclavian flap aortoplasty. However, the technique of patch aortoplasty, routinely performed in the last 24 years of this series seemed by far the most satisfactory procedure. Subclavian flap aortoplasty was carried out in a selected group of younger children. Associated cardiac anomalies influenced the results adversely. The overall operative mortality was 5.8 percent. Hypertension did not regress in 11.7 per cent of patients inspite of a successful operation as judged by the return of peripheral pulses in the lower limbs. Re-coarctation was not seen in this series. The overall results of operation for coarctation of the aorta have been very satisfactory and comparable with those in other published series.
