ductus arteriosus









































the ductus arteriosus, also called the ductus botalli, is a blood vessel in the developing fetus connecting the trunk of the pulmonary artery to the proximal descending aorta. it allows most of the blood from the right ventricle to bypass the fetus's fluid-filled non-functioning lungs. upon closure at birth, it becomes the ligamentum arteriosum. 









































section::::development and structure.









































the ductus arteriosus is formed from the left 6th aortic arch during embryonic development and attaches to the final part of the aortic arch (the isthmus of aorta) and the first part of the pulmonary artery

section::::clinical significance.:patent ductus arteriosus.:consequences.









































failure of the ductus arteriosus to close after birth results in a condition called patent ductus arteriosus, which results in the abnormal flow of blood from the aorta to the pulmonary artery: a left-to-right shunt. if left uncorrected, this usually leads to pulmonary hypertension followed by right ventricular heart failure, as well as possible cardiac arrhythmias.
