ductus arteriosus

A short shunting artery lying between the main artery to the lungs (pulmonary artery) and the main artery to the body (aorta). During fetal life blood need not pass through the lungs and this vessel acts as a bypass. It normally closes soon after birth. If it fails to do so (patent ductus arteriosus) the blood is insufficiently oxygenated and there may be interference with growth and development and additional strain on the heart.

ductus arteriosus

a blood vessel found in foetal mammals which connects the pulmonary artery to the AORTA and thus creates a bypass to the lungs. See Fig. 138 . The vessel closes soon after birth so that all blood is now sent through the lungs for oxygenation. Occasionally the vessel does not close completely, which may cause a condition called BLUE BABY.
