Learn about the operation to correct PDA and recovery.</p><h2>What is a patent ductus arteriosus?</h2><p>In the womb, baby's oxygen comes from the mother. Since there is no need for blood to pass through the lungs of the fetus, the blood is diverted away from the lungs, to the rest of the body, by an artery called the ductus arteriosus.</p><p>Once a baby is born and takes their first breath, the ductus arteriosus is no longer needed and begins to close. Under normal circumstances, the ductus arteriosus is completely closed in a few weeks.</p><p>With some babies, this process of closure either does not happen at all or does not happen completely, leaving a small opening. As a result, normal blood flow is affected. This condition is called patent ductus arteriosus (PDA). Patent, in this context, means open.</p><p>Sometimes, the body just needs a little extra time for the PDA to close. Certain medications can also be used to encourage a PDA to close. If time or medications do not close the PDA, heart catheterization or surgery may be used. This information describes what happens during heart catheterization to close a PDA.</p> <figure><span class="asset-image-title">PDA closure with </span> <span class="asset-image-title"> catheterization</span><img src="https://assets.aboutkidshealth.ca/akhassets/Patent_ductus_closure_MED_ILL_EN.png" alt="" /><figcaption class="asset-image-caption">A</figcaption><figcaption class="asset-image-caption"> catheter is threaded through a blood vessel in the body up to the heart.

The groin is the area at the top of the leg. Then, the catheter is threaded through the vein or artery to your child's heart.</p><p>The doctor who does the procedure is a cardiologist, which means a doctor who works on the heart and blood vessels. This may not be your child's regular cardiologist.</p><h2>Key points</h2> <ul> <li>If a PDA does not close on its own, a small closure device can be placed in the heart catheterization lab. </li> <li>Your child will need a general anaesthetic for the procedure. </li> <li>Although there are some risks, serious problems are rare. </li> <li>Most children can go home on the same day as the procedure. </li> </ul><h2>What does the closure device look like and how does it stay in place?</h2> <p>The closure device is made of metal and mesh material. It looks like a short tube with different-sized discs (circles) on either end. Before it is put in, the discs are folded so the device will fit in the catheter. When it is in the right place, one disc opens up as the device is moved out of the catheter. The tube portion plugs the PDA, and the other disc opens up on the opposite side. The PDA is now closed, with the device acting as a plug. This stops the blood from flowing through the PDA. </p> <h2>What happens during the procedure</h2> <p>The procedure is performed while your child is under a general anaesthetic. This means that your child will be asleep during the procedure. </p> <p>During the procedure, the doctor inserts a catheter into a blood vessel in the groin at the top of your child's leg. The catheter is moved up the blood vessel into the heart and into the PDA. An X-ray picture is then taken of the PDA. A closure device is threaded through the catheter and placed into the PDA. </p> <p>Once the device is in place, the doctor takes out the catheter and covers the cut on your child's leg with a bandage.</p> <h2>The procedure takes about one to three hours</h2> <p>The procedure usually takes one to three hours. After the procedure, your child will go to the recovery room for one to six hours to wake up from the anaesthesia. </p><h2>After the procedure</h2> <p>The cardiologist will let you know when your child can go home. Your child will stay in the hospital for at least four to six hours <a href="/Article?contentid=1214&language=English">after the procedure</a>. Most children can go home on the same day as the procedure. </p> <p>If your child needs to stay overnight, they will be transferred to the inpatient unit.</p> <p>Your child will need to have an X-ray the morning after the procedure to make sure the closure device has not moved. If your child goes home overnight, you will need to bring your child back in the morning to have the X-ray. </p>

Étant donné que le sang n'a pas besoin de passer dans les poumons du fœtus, le sang est détourné des poumons vers le reste de l'organisme par une voie appelée le canal artériel. </p><p>Une fois que le bébé est né et qu'il a pris sa première inspiration, le canal artériel n'est plus nécessaire et commence à se fermer. En temps normal, le canal artériel est complètement fermé après quelques semaines. </p><p>Chez certains bébés, ce processus de fermeture ne produit pas ou ne se produit que partiellement, ce qui laisse une petite ouverture. Par conséquent, la circulation normale du sang est entravée. C'est ce que l'on appelle la <a href="/Article?contentid=1617&language=French">persistance du canal artériel​</a> (PCA). Le terme « persistance », dans ce contexte, signifie « ouvert ». </p> <figure><span class="asset-image-title">Fermeture d'une persistance du canal artériel (PCA) au moyen d'un cathéter</span><img src="https://assets.aboutkidshealth.ca/akhassets/Patent_ductus_closure_MED_ILL_FR.png" alt="" /><figcaption class="asset-image-caption">On insère un cathéter dans un vaisseau sanguin jusqu'à ce qu'il atteigne le cœur. Un dispositif de fermeture est inséré dans la PCA. Une fois qu'il est en place, on retire le cathéter.</figcaption></figure> <p>Parfois, le corps a seulement besoin d'un peu plus de temps pour que la PCA se ferme. Certains médicaments peuvent aussi servir à stimuler la fermeture d'une PCA. Si le temps ou les médicaments ne parviennent pas à fermer la PCA, la cathérisation ou une opération pourraient être nécessaires. Les renseignements ci-dessous décrivent ce qui se passe pendant la cathétérisation du cœur pour fermer une PCA.</p><h2>Qu'est-ce que la cathétérisation du cœur?</h2><p>Pendant la <a href="/Article?contentid=59&language=French">cathétérisation</a>, le médecin place délicatement un long tube mince appelé cathéter dans une veine ou une artère du cou ou de l'aine de votre enfant. L'aine est la région au-dessus de la jambe. Le cathéter est ensuite déplacé dans la veine ou l'artère qui mène au cœur.</p><p>Le médecin qui fait cette procédure est un cardiologue, c'est-à-dire un médecin spécialiste du cœur et des vaisseaux sanguins. Il pourrait ne pas être le cardiologue habituel de votre enfant.</p><h2>À retenir</h2> <ul><li>Si une PCA ne se ferme pas toute seule, un petit instrument y sera placé dans le laboratoire de cathétérisation du cœur.</li> <li>Votre enfant aura besoin d'une anesthésie locale.</li> <li>Bien qu'il y ait certains risques, les problèmes graves ​sont rares.</li> <li>La plupart des enfants peuvent retourner à la maison le même jour.</li></ul><h2>De quoi a l' air l' instrument de fermeture et comment demeure-t-il en place?</h2> <p>L' instrument de fermeture est fait de métal et de maille. Il ressemble à un court tube avec des disques (cercles) de différentes tailles à chaque bout. Avant d' être inséré, les disques sont repliés pour que le dispositif puisse entrer dans le cathéter. Quand le dispositif est bien placé, un disque s' ouvre, et l' instrument sort du cathéter. La partie qui sort du tube bouche l' ouverture, et l' autre disque à l' autre bout s' ouvre. La PCA est maintenant fermée par l' instrument qui agit comme un bouchon, ce qui empêche le sang de couler dans la PCA.</p> <h2>Ce qui se passe pendant l' intervention</h2> <p>Votre enfant est sous anesthésie générale pendant l' intervention, c' est-à-dire qu' il sera endormi.</p> <p>Pendant l' intervention, le médecin insère le cathéter dans un vaisseau sanguin dans l' aine, en haut de la jambe de votre enfant. Le cathéter est déplacé dans le vaisseau sanguin en remontant jusqu' au cœur et dans la PCA. on prend ensuite une radiographie de la PCA. Un instrument de fermeture est ensuite inséré dans le cathéter et placé dans la PCA.</p> <p>Une fois l' instrument en place, le médecin retire le cathéter et couvre l' incision sur la jambe de votre enfant d' un pansement.</p> <h2>La procédure prend 1 à 3 heures</h2> <p>La procédure prend normalement 1 à 3 heures, après quoi votre enfant sera transféré en salle de réveil pendant 1 à 6 heures, où il se réveillera de l' anesthésie.</p><h2>Après l'intervention</h2> <p>Le cardiologue vous dira quand votre enfant pourra retourner à la maison. Votre enfant demeurera à l'hôpital pendant 4 à 6 heures après l'intervention, et la plupart des enfants peuvent retourner à la maison le jour de l'intervention.</p> <p>Si votre enfant doit passer la nuit à l'hôpital, on pourrait le transférer à l'unité de soins.</p> <p>Votre enfant devra subir une radiographie le matin après l'intervention pour que l'on vérifie si l'instrument de fermeture est toujours en place. Si votre enfant retourne à la maison, vous devrez ramener votre enfant à l'hôpital le matin pour la radiographie.</p>

At this time an echocardiogram, which is a type of ultrasound of the heart, will be done to ensure that the PDA is properly closed. </p> <p>Write the date and time of the appointment here:</p> <p> </p> <h2>Antibiotics to prevent infectious endocarditis</h2> <p>Your child will need antibiotics before and after dental treatments for six months after the procedure. These drugs help prevent a heart infection called infectious endocarditis. Your child's cardiologist will tell you if this is needed for a longer time. </p><h2>What does the closure device look like and how does it stay in place?</h2> <p>The closure device is made of metal and mesh material. It looks like a short tube with different-sized discs (circles) on either end. Before it is put in, the discs are folded so the device will fit in the catheter.

If your child goes home overnight, you will need to bring your child back in the morning to have the X-ray. </p><h2>There are small risks of complications from the procedure</h2> <p>Generally, heart catheterization is a fairly low-risk procedure, but it is not risk-free. The doctor will explain the risks of heart catheterization to you in more detail before you give your consent for the procedure. The most common risks with PDA closure are as follows: </p> <h3>The catheter may break through a blood vessel</h3> <p>There is a very small risk that the catheter may break through a blood vessel or the heart wall. To reduce this risk, we use a type of X-ray called fluoroscopy to see where the catheter is at all times. </p> <h3>Complications may occur with the closure device</h3> <p>While the device is being put in position, there is a risk that it may be put in the wrong place, move or fall out of the PDA. If this happens, the cardiologist will try to put it back in place. If this is not possible, surgery will be arranged to take out the device and close the PDA. </p> <p>A more common complication is a small leak through the closure device. Usually this disappears with time. In rare cases, a second device may be placed over the first to stop the leak completely. </p>https://assets.aboutkidshealth.ca/akhassets/Patent_ductus_closure_MED_ILL_EN.pngPatent ductus arteriosus (PDA): Closure in the heart catheterization lab
