ductus

 [duk´tus] (pl. duc´tus) (L.)
ductus arterio´sus a fetal blood vessel that joins the aorta and pulmonary artery.
ductus de´ferens the excretory duct of the testis, which joins the excretory duct of the seminal vesicle to form the ejaculatory duct; called also vas deferens.
patent ductus arteriosus see patent ductus arteriosus.
ductus veno´sus a major blood channel that develops through the embryonic liver from the left umbilical vein to the inferior vena cava.

duc·tus ar·te·ri·o·sus

a fetal vessel connecting the left pulmonary artery with the descending aorta; in the first 2 months after birth, it normally changes into a fibrous cord, the ligamentum arteriosum; persistent postnatal patentcy is a correctable cardiovascular handicap.

ductus arteriosus

(dŭk′təs är-tîr′ē-ō′səs)
n.
A fetal blood vessel that connects the left pulmonary artery with the descending aorta and that normally closes at birth.

duc·tus ar·te·ri·o·sus

(dŭk'tŭs ahr-tē-rē-ō'sŭs)
A fetal vessel connecting the left pulmonary artery with the descending aorta; in the first 2 months after birth, it normally changes into a fibrous cord called the ligamentum arteriosum; occasional postnatal failure to close causes a surgically correctable cardiovascular handicap.
Synonym(s): arterial canal, arterial duct, Botallo duct.

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.

Ductus arteriosus

The temporary channel or blood vessel between the aorta and pulmonary artery in the fetus.

Botallo,

Botallo duct - a fetal vessel connecting the left pulmonary artery with the descending aorta. Synonym(s): ductus arteriosus
Botallo foramen - the orifice of communication between the two atria of the fetal heart.
Botallo ligament - the remains of the ductus arteriosus. Synonym(s): ligamentum arteriosum
