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. This small vessel most often closes Shortly after birth when the baby starts to breathe on their own. If it does not close, it is called a patent ductus arteriosus. This could cause problems later in life.
In most cases, the doctor will close off the opening using medicine. If this does not work, then other techniques are used.
Sometimes the PDA can be closed with a procedure that does not involve surgery. The procedure is most often done in a laboratory that uses x-rays. In this procedure, the surgeon makes a small cut in the groin. A wire and tube called a catheter is inserted into an artery in the leg and is passed up to the heart. Then, a small metal coil or another device is passed through the catheter into the infant’s ductus arteriosus artery. The coil or other device blocks the blood flow, and this corrects the problem.
Another method is to make a small surgical cut on the left side of the chest. The surgeon finds the PDA and then ties off or clips the ductus arteriosus, or divides and cuts it. Tying off the ductus arteriosus is called ligation.
