Patent ductus arteriosus (PDA) is a condition in which the ductus arteriosus does not close. The word “patent” means open. The ductus arteriosus is a blood vessel that allows blood to go around a baby’s lungs before birth. Soon after the infant is born and the lungs fill with air, the ductus arteriosus is no longer needed. It most often closes in a couple of days after birth. If the vessel doesn’t close, it is referred to as a PDA. This condition requires repair with a closure device.
A transcatheter device closure is a procedure that uses a thin, hollow tube placed into a blood vessel. The physician passes a small metal coil or other blocking device through the catheter to the site of the PDA. This blocks blood flow through the vessel.
Surgery may be needed if the catheter procedure does not work. Surgery involves making a small cut between the ribs to repair the PDA.
