Patent Ductus Arteriosus Treatment

Patent ductus arteriosus may close on its own over time. Premature babies are more likely to have patent ductus arteriosus close on its own. If your baby’s ductus is small and not causing problems, your doctor may suggest waiting to see if it closes in your child’s first year or two.

If the ductus is large, it is likely to cause problems or has already caused problems with your baby’s blood flow, breathing or heart function. Your doctor may suggest taking steps to close it.

Patent Ductus Arteriosus Treatment Options


In premature babies, medicines may make the ductus tighten and close. Doctors use indomethacin or ibuprofen to do this.


In full-term babies, the ductus arteriosus can usually be closed with a cardiac catheterization procedure. The doctor uses a small, thin tube (catheter), inserted through a blood vessel in the leg, to close the ductus arteriosus. This procedure is done while your child is sedated (general anesthesia).


Some premature infants and children who have a ductus arteriosus that is too large to close with cardiac catheterization may need surgery.
