[A simplified catheter technique for the occlusion of a large persistent ductus arteriosus].

Transcatheter occlusion of a persistent ductus arteriosus with a diameter of more than 9 mm is considered difficult or impossible with the currently available techniques. Usually, these patients have to be operated. We used a simple technique to occlude a 13-mm ductus using two Rashkind umbrellas introduced simultaneously through the left and right femoral veins. Complete closure was demonstrated by echo- and angiography.
