Coil Occlusion for Patent Ductus Arteriosus Closure in Children


Patent ductus arteriosus (PDA) coil occlusion is a procedure to close the opening between your child's aorta and pulmonary artery.


Before your child's procedure:

  • Informed consent is a legal document that explains the tests, treatments, or procedures that your child may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your child's medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done to your child. Make sure all of your questions are answered.
  • An IV is a small tube placed in your child's vein. Healthcare providers use the IV to give your child medicine or liquids.
  • Blood tests may be done to check your child's condition before the procedure. Your child may need to have blood drawn more than once.
  • Medicines:
    • Antibiotics help your child fight an infection.
    • Antinausea medicine helps calm your child's stomach and prevent vomiting.
    • Blood thinner medicine helps prevent clots from forming during the procedure.
  • Anesthesia makes your child comfortable during the procedure. Healthcare providers will work with you to decide which anesthesia is best for your child.
    • General anesthesia keeps your child asleep and free from pain during the procedure. Healthcare providers may give your child anesthesia through his IV. Your child may breathe it in through a mask or a tube placed down his throat. The tube may cause your child to have a sore throat when he wakes up.
    • Local anesthesia is a shot used to numb the area where the catheter is put in and dull the pain. Your child may still feel pressure or pushing during the procedure.

During your child's procedure:

Catheters will be put into the blood vessels in your child's groin, neck, or arm through an incision. The catheters are gently pushed through the blood vessels and heart. Your child's healthcare providers may use dye and x-rays during the procedure. The dye helps the pictures show up better. Healthcare providers will use 1 or more tiny coils to close your child's PDA. The catheters will be removed after the PDA is closed. Your child may have stitches to stop the bleeding. A pressure bag or bandage may be put on the incisions for 2 or more hours to help stop bleeding.

After your child's procedure:

Your child will be taken to a room to rest. Your child will need to lie flat and keep his leg or arm still for about 4 hours. This helps prevent bleeding. Do not let your child get out of bed until healthcare providers say it is okay. When healthcare providers see that he is okay, he will be taken to his room.

  • Tell your child's healthcare provider if your child has any of the following:
    • Chest pain or discomfort
    • Change in color or temperature of his arm or leg
    • Pain, numbness, or tingling in his arm or leg
    • Pain in his back, thigh, or groin
    • Nausea
    • Excessive sweating
  • Your child will be able to eat and drink gradually after his procedure. He will begin with ice chips or clear liquids such as water, broth, juice, and clear soft drinks. If his stomach does not become upset, he may then eat soft foods, such as ice cream and applesauce. Once he can eat soft foods easily, he may slowly begin to eat solid foods.


  • Catheters may cause bleeding, bruising, and soreness around the area where they were placed. Your child could bleed more than expected or get an infection. He may also need surgery to repair the PDA. Your child could get air bubbles in his blood or a blood clot. Air bubbles and blood clots can cause a stroke. Fluid could build up in your child's lungs and cause trouble breathing. These problems may become life-threatening.
  • Your child may get a pneumothorax. This happens when air gets inside the space between his lungs and chest wall. Your child could have an allergic reaction or kidney problems from the dye used during the procedure. The coil could move out of place and your child may need surgery to remove the coil and repair the PDA. Without this procedure, your child's symptoms could get worse. Your child may develop heart failure and his lungs could be damaged. These problems may be life-threatening.


You have the right to help plan your child's care. Learn about your child's health condition and how it may be treated. Discuss treatment options with your child's caregivers to decide what care you want for your child.
