title: [Residual shunts after application of the Rushkind occlusion system in closure of persistent ductus arteriosus. Insertion of a second device].
abstract: From May 1991 to August 1994, we performed transcatheter closure of patent ductus arteriosus with Rashkind umbrella system in 25 patients. In one, the device had embolism, to the right pulmonary artery and was operated 24 hs afterwards without complications. Seven had residual shunts, two had subsequent surgery, two are being followed (one for mild and one for moderate residual shunt). In the other three cases we inserted a second device. We used a 12 mm device in two cases and a 17 mm device in the other. Two cases had total occlusion 24 hrs after and in one had mild residual shunt without clinical repercussion. There were no complications. All had electrocardiographic and clinical improvement, take no medication, and their cardiomegaly had decreased (Cardiac index pre 61 vs post 54%). In conclusion the insertion of a second device is safe and effective alternative for residual shunt after first Rashkind occluder.
