Answer

Introduced in 1992, Gianturco spring occluding coils have been the most common device used for patent ductus arteriosus (PDA) occlusion for many years. The coils are delivered to the patent ductus arteriosus (PDA) via venous or arterial systems: 1-5 coils are placed in the ductus. In experienced hands with proper patient selection, this has become a procedure associated with high success and low morbidity. This method has been reported to be 75-100% effective but is limited to ductus that are only 4-5 mm in diameter. Coil occlusion is best suited to close a patent ductus arteriosus (PDA) with a minimal internal diameter of less than 2.5 mm. Fue et al showed that very high closure rates could be obtained in ducts less than 3 mm using coils, but that success significantly dropped when the ducts exceeded 3 mm.
