From January 1981 to September 1996, 447 patients with patent ductus arteriosus (122 male and 325 female) aged from 0.75 to 14 years, underwent surgery in our institute. Systolic blood pressure was maintained below 90 mm Hg with sodium nitroprusside and a vertical incision was made under the left axilla through the third intercostal space. Simple ligation was performed when the ductus was less than 10 mm in diameter. In 313 patients with a patent ductus arteriosus of 10 mm diameter or greater, a Dacron cushion was placed under the ligature. There was no death or evidence of residual patency. We recommend careful control of systolic blood pressure during the whole procedure and the use of a cushion under the ligature when closing a large ductus.
