Definitions for "Patent ductus arteriosus"
Heart problem that is seen most commonly in premature babies.
A condition in which the ductus arteriosus fails to close shortly after birth. This results in a significant right to left shunt of blood. Babies with this condition often develop heart and lung failure. Treatment with drugs (indomethacin) is possible, and surgical ligation is often necessary.
a blood vessel present in the fetus that allows blood coming from the placenta that is rich in oxygen to bypass the left side of the heart and lungs and flow through this blood vessel to the rest of the body. It usually closes in the first two weeks of life in term infants but may remain open in the preterm infant, requiring treatment to close it.
