Severe mechanical hemolysis ocurred in a 22 month old girl after place
ment of a 38-5-10 coil in the arterial duct. She had previously underg
one percutaneous closure using the Rashkind technique 14 months before
insertion of the coil, but remained with a moderate residual shunt. S
urgical removal of the devices and division of the duct were required
to abolish the hemolysis.
