The Doppler Evaluation of Patent Ductus Arteriosus

Abstract

In normal fetal circulation, the aorta and the pulmonary artery are connected at the level of the pulmonary artery bifurcation and the aorta just distal to the left subclavian artery by the ductus arteriosus. It closes in response to increased oxygen in the blood flow through the ductus shortly after birth. This functional closure of the ductus is followed by an anatomic closure in the first two to three weeks of life, however it may remain patent, in which case there is a shunting of blood flow from the aorta to the pulmonary artery. This shunting may also be from the pulmonary artery to the aorta if there is a severe pulmonary hypertension.
