Transcatheter Closure of Patent Ductus Arteriosus in 10 Children

Between April and July 1991, we attempted transcatheter umbrella closure using the Rashkind PDA occluder, of patent ductus arteriosus in 10 patients. The patients ranged in age from 18 months to 11 years and their weights from 9. 7 to 35 kg. The ductus at its narrowest diameter varied from 3 to 9 mm. Complete closure was achieved in 8 patients soon after the procedure was carried out. One patient retained residual ductal murmur despite correct placement of the occlusion device. One patient who had ductal Doppler flow pattern immediately after procedure was found to have been freed from this pattern and complete closure was achieved four months later. Postrelease embolization did not occur. No patient developed any vascular complication.
