A SIMPLE OCCLUSION TECHNIQUE FOR LARGE PE RSISTENT DUCTUS-ARTERIOSUS

Transcatheter occlusion of a persistent ductus arteriosus with a diame ter of more than 9 mm is considered difficult or impossible with the c urrently available techniques. Usually, these patients have to be oper ated. We used a simple technique to occlude a 13-mm ductus using two R ashkind umbrellas introduced simultaneously through the left and right femoral veins. Complete closure was demonstrated by echo- and angiogr aphy.
