The ligamentum venosum courses along the visceral/posterior aspect of the liver in the fossa for ductus venosum, which separates the caudate lobe and the left lobe. Fetal circulation. The ductus venosus (red), which becomes the ligamentum venosum , connects the umbilical vein to the inferior vena cava .
ligamentum arteriosum: extra-hepatic portion of the fetal left umbilical vein: ligamentum teres hepatis ("round ligament of the liver") intra-hepatic portion of the fetal left umbilical vein (ductus venosus) ligamentum venosum: proximal portions of the fetal left and right umbilical arteries umbilical branches of the internal iliac arteries
The caudate lobe of the liver is bounded below by the porta hepatis, on the right by the fossa for the inferior vena cava, and on the left by the fossa for the ductus venosus and the physiological division of the liver, called the ligamentum venosum. It looks backward, being nearly vertical in position; it is longer from above downward than ...
A liver segment is one of eight segments of the liver as described in the widely used Couinaud classification (named after Claude Couinaud) in the anatomy of the liver.This system divides the lobes of the liver into eight segments based on a transverse plane through the bifurcation of the main portal vein, [1] arranged in a clockwise manner starting from the caudate lobe.
After the ductus venosus closes, its remnant is known as ligamentum venosum. If the ductus venosus fails to occlude after birth, it remains patent (open), and the individual is said to have a patent ductus venosus and thus an intrahepatic portosystemic shunt (PSS). [4] This condition is hereditary in some dog breeds (e.g. Irish Wolfhound).
Within the child, the umbilical vein and ductus venosus close up, and degenerate into fibrous remnants known as the round ligament of the liver and the ligamentum venosum respectively. Part of each umbilical artery closes up (degenerating into what are known as the medial umbilical ligaments ), while the remaining sections are retained as part ...
The hepatogastric ligament or gastrohepatic ligament connects the liver to the lesser curvature of the stomach.It contains the right and the left gastric arteries.In the abdominal cavity, it separates the greater and lesser sacs on the right.
The round ligament of the liver, ligamentum teres or ligamentum teres hepatis is a ligament that forms part of the free edge of the falciform ligament of the liver. It connects the liver to the umbilicus. It is the remnant of the left umbilical vein. The round ligament divides the left part of the liver into medial and lateral sections.
