title: [Acute intravascular hemolysis after complete occlusion of a patent ductus arteriosus by detachable coils].
abstract: A case of acute intravascular haemolysis after complete occlusion of a patent ductus arteriosus by detachable coils in a 10 months old child is reported. The child had a patent ductus arteriosus, a small secundum atrial defect, mild valvular pulmonary stenosis, and stenosis of branches of the pulmonary artery not diagnosed before closure of the ductus. Haemolysis developed several hours after complete occlusion of the ductus by two detachable coils. The mechanism of the haemolysis was thought to be the presence of metallic spirals in the left pulmonary artery, just beyond stenosis situated at the origin of this artery. Simple balloon dilatation of the left pulmonary artery stenosis resulted in the complete regression of haemolysis.
