This procedure may be done in the neonatal intensive care unit (NICU). Tying off the ductus arteriosus is called ligation. The surgeon finds the PDA and then ties off or clips the ductus arteriosus, or divides and cuts it. Another method is to make a small surgical cut on the left side of the chest.The coil or other device blocks the blood flow, and this corrects the problem. Then, a small metal coil or another device is passed through the catheter into the infant's ductus arteriosus artery. A wire and tube called a catheter is inserted into an artery in the leg and passed it up to the heart. In this procedure, the surgeon makes a small cut in the groin. The procedure is most often done in a laboratory that uses x-rays. Sometimes the PDA can be closed with a procedure that does not involve surgery.If this does not work, then other techniques are used. In most cases, the doctor will close off the opening using medicine.This small vessel most often closes shortly after birth when the baby starts to breathe on their own. Before birth, the baby has a blood vessel that runs between the aorta (the main artery to the body) and the pulmonary artery (the main artery to the lungs), called the ductus arteriosus.There are many types of pediatric heart surgery.
