Abstract
A persistent ductus arteriosus was occluded with an Ivalon plug via a catheter delivery system, introduced through the femoral artery, in 38 patients, aged 11-72 years (mean 39). The mean diameter of the ductus was 4.5 .+-. 1.2 *2-9) mm, mean pulmonary artery pressure 30/12 (15.5-70/27) mm Hg. In two patients the plug became dislocated after two and seven weeks, respectively, without serious consequences. In all others the occlusion was successful and permanent. There were only a few complications and none was serious. During a follow-up period of up to four years there were no instances of recanalization or further plug dislocation.
