ductus venosus

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 ve·no·sus

in the fetus, continuation of the left umbilical vein through the liver to the vena cava inferior; after birth, its lumen becomes obliterated, forming the ligamentum venosum.

Structural alterations can affect the foetal development, because nutrient exchange is very delicate during gestation period (Ferreira et al., 2009).In addition to these vessels, foetal circulatory circuit has a developing aorta and ductus venosus which shunts off most of the blood flowing from the umbilical vein away from the liver into the caudal vena cava (Brandow, 2009), the blood then flows into the right atrium and enters the foramen ovale into the left atrium by passing the pulmonary circulation (McGeady et al., 2006).

Investigations continue exploring additional ultrasound parameters for DS risk assessment, (21) Recent studies have found that blood flow through the fetal Ductus Venosus (19,20), fetal tricuspid regurgitation, and the frontomaxillary facial angles (22) are all promising.

The blood returning to the fetus through the umbilical vein mostly passes through the ductus venosus and therefore only a small amount goes to the liver.
