[Intravascular hemolysis following percutaneous occlusion of the ductus arteriosus].
Transcatheter occlusion of patent ductus arteriosus has become a safe and successful technique, but it's not free of complications. We present the case of a two-year-old boy who underwent routine transcatheter closure of his patent ductus arteriosus, using a "coil" device. Twenty hours later he developed severe persistent hemolysis in association with residual ductal flow. Patient's clinical situation became stable when the device was removed. Pulmonary embolization of the device and hemolysis are the main complications of percutaneous closure of the patent ductus arteriosus. Hemolysis occurs rarely (0.5%) and is always associated with the presence of residual ductal flow. Several approaches to this problem have been described. Mild cases may require no intervention; however, when severe hemolysis is present, removal of the device may be needed, proceeding with surgical repair of the patent ductus arteriosus.
