In premature infants, an attempt is made to close the patent ductus by fluid restriction and prostaglandin inhibitors (e.g., indomethacin). Surgical ligation (tying) of the patent ductus is undertaken if these steps do not close the ductus.
In full-term infants, surgical ligation of the patent ductus is recommended if heart failure develops. If the infant doesn't have symptoms, the surgery is postponed until 6 months to 3 years of age, unless problems develop.
Other treatments include closing the ductus with plugs or coils. These are deployed through catheters placed in arteries in the groin. Intravascular coils are often used for the treating small PDAs.
