Definition of ductus arteriosus in English English dictionary
- a shunt that connects the pulmonary artery to the aorta during fetal development
- Channel between the pulmonary artery and the aorta in the fetus, which bypasses the lungs to distribute oxygen received through the placenta from the mother's blood. It normally closes once the baby is born and the lungs inflate, separating the pulmonary and systemic circulations. Closure before birth causes circulatory problems. If the ductus stays open after birth (patent ductus arteriosus, more common in premature births), oxygenated and deoxygenated blood mix. Alone, this may not be serious; in some heart malformations it is even necessary for life
- a blood vessel in a fetus that bypasses pulmonary circulation by connecting the pulmonary artery directly to the ascending aorta; normally closes at birth
- patent ductus arteriosus
- a ductus arteriosus that failed to close at birth; may require surgical correction
