PDA Occlusion

What is PDA Occlusion?

PDA coil closure is done during a heart catheterization or "heart cath". A heart cath is a procedure in which catheters (long, thin, bendable tubes) are gently threaded (guided) into the heart. Your caregivers push 1 or more tiny metal coils through a catheter and plug them into the PDA. If the PDA coil closes your PDA, you may not need surgery. You may go home the same day or may stay in the hospital after the PDA is closed.

During Your PDA Closure

You will change into a hospital gown. Your will get medicine to make him relaxed and drowsy. He will be taken on a stretcher to the room where the PDA closure will be done. Your will get an IV and may get more medicine to make him go to sleep. Once you are asleep, catheters will be put into the blood vessels in your groin, neck, or arm. The catheters are gently threaded (pushed) through the blood vessels and heart.

Caregivers will repair your PDA. Your caregivers may use dye and x-rays during the procedure. Caregivers may use these before and after the PDA closure to look at your PDA. During the procedure, caregivers will use 1 or more tiny coils to plug your PDA closed. The catheters will be removed after the PDA is closed. Caregivers will put pressure on the area where the catheters came out. This is to stop the bleeding. A pressure bag or bandage may be put in place for 2 or more hours. You may have stitches to stop the bleeding. It is very important for you to lie flat and to keep the leg or place that had the catheter very still. This is to prevent bleeding.

After Your PDA Closure

Aftercare: Your will be taken to a recovery area. Then, your may be taken to a hospital unit or room, or he may go home. Caregivers will watch you closely for any problems. Caregivers will check your vital signs (pulse, blood pressure, and breathing) every 15 minutes for 1 to 2 hours. The pulses in your feet or wrists will also be checked often. Your toes and fingers will be checked to see if they are warm. Tell your caregiver if your has any of the following:

  • Chest pain or discomfort.
  • Change in color or temperature of your arm or leg.
  • Swelling or bleeding from the area where the catheter was.
  • Pain, numbness, or tingling in your arm or leg.
  • Pain in your back, thigh, or groin.
  • Nausea (your feels sick to your stomach).
  • Sweating a lot.

RISKS of PDA Occlusion

There are risks in putting catheters in the blood vessels. This could cause bleeding, a bruise, and soreness around the place where a catheter went in. You could bleed and need a blood transfusion (trans-FEW-shun) or surgery to repair the hole. You could get air bubbles or a blood clot from the heart cath or device. Air bubbles could give you a stroke. Blood clots may go to your lungs or brain and cause a stroke. The clots may go to your arm or leg and stop the blood flow. Fluid could build up in your lungs and cause trouble breathing.

You could get a collapsed lung or an infection. You could have an allergic reaction or kidney problems from the dye used during the procedure. A blood clot may form on the coil that was used to close the PDA. The coil could move out of place. Then you may need surgery to remove the coil and repair the PDA. Caregivers will watch you closely for these problems.

If your does not have your PDA closed, your health condition could get worse. Your heart could fail (wear out), your lungs could be damaged, and you could die. Call your caregiver if you are worried or have questions about your PDA, medicine, or care.
