Patent ductus arteriosus PDA is an extra blood vessel found in babies before birth and just after birth. In most babies who have an otherwise normal heartthe PDA will shrink and close on its own in the first few days of life.
If it stays open longer, it may cause extra blood to flow to the lungs. Problems are most likely arrterioso the PDA is large.
Persistencia del ductus arterioso (PDA)
Some smaller PDAs that don’t close early will seal up on their own by the time the child is a year old. A patent ductus arteriosus PAY-tent DUK-tus are-teer-ee-OH-sus is more likely to stay open in a premature infantparticularly if the baby has lung disease. When this happens, doctors might need to close the PDA. The ductus arteriosus is a normal blood vessel that connects two major arteries — the aorta and the pulmonary artery — that carry blood away from the heart.
The lungs are not used while a fetus is in the womb because the baby gets oxygen directly from the mother’s placenta. The ductus arteriosus carries blood away from the lungs and sends it directly to the body.
When a newborn breathes and begins to use the lungs, the ductus is no longer needed and usually closes by itself during the first 2 euctus after birth. If the ductus doesn’t close, the result is a patent meaning “open” ductus arteriosus. The PDA lets oxygen-rich blood blood high in oxygen from the aorta mix with oxygen-poor blood blood low in oxygen in the pulmonary artery.
As a result, too much blood flows into the lungs, which puts a strain on the heart and increases blood pressure in the pulmonary arteries. In infants born with other heart problems that decrease blood flow from the heart to the lungs or decrease the flow of oxygen-rich blood to the body, the PDA may actually help, and the doctor might prescribe medicine to keep the ductus arteriosus open.
The cause of PDA is not known, but genetics might play a role. PDA is more common in premature babies and affects twice as many girls as boys.
It’s also common among babies with neonatal zrterioso distress syndrome, babies with genetic disorders such as Down syndromeand babies whose mothers had rubella also called German measles during pregnancy.
If a PDA is suspected, the doctor will use a stethoscope to listen for a heart murmurwhich is often heard in babies with PDAs. Follow-up tests might include:.

The three treatment options for PDA are medicine, catheter-based proceduresand surgery. A doctor will close a PDA if the size afterioso the opening is big enough that the lungs could become overloaded with blood, a condition that can lead to an enlarged heart.
A doctor also might close a PDA to reduce the risk of developing arteiroso heart infection known as endocarditiswhich affects the tissue lining the heart and blood vessels.
Endocarditis is serious and requires treatment with intravenous IV antibiotics. For specific medical advice, diagnoses, and treatment, consult your doctor. More on this topic for:
