Caudate lobe of liver
Encyclopedia
The caudate lobe is situated upon the postero-superior surface of the liver on the right lobe of the liver, opposite the tenth and eleventh thoracic vertebrae
. It is bounded on the left side by the physiological division of the liver called the ligamentum venosum
.
It is bounded, below, by the porta; on the right, by the fossa for the inferior vena cava
; and, on the left, by the fossa for the ductus venosus
.
It looks backward, being nearly vertical in position; it is longer from above downward than from side to side, and is somewhat concave in the transverse direction.
The caudate process is a small elevation of the hepatic substance extending obliquely and laterally, from the lower extremity of the caudate lobe to the under surface of the right lobe.
It is situated behind the porta
, and separates the fossa for the gall-bladder from the commencement of the fossa for the inferior vena cava
.
Budd-Chiari syndrome
, caused by occlusion of hepatic venous outflow, can lead to hypertrophy of the caudate lobe due to its own caval anastomosis that allows for continued function of this lobe of the liver.
Thoracic vertebrae
In human anatomy, twelve thoracic vertebrae compose the middle segment of the vertebral column, between the cervical vertebrae and the lumbar vertebrae. They are intermediate in size between those of the cervical and lumbar regions; they increase in size as one proceeds down the spine, the upper...

Ligamentum venosum
The ligamentum venosum is the fibrous remnant of the ductus venosus of the fetal circulation. Usually, it is attached to the left branch of the portal vein within the porta hepatis...

The inferior vena cava , also known as the posterior vena cava, is the large vein that carries de-oxygenated blood from the lower half of the body into the right atrium of the heart....

Ductus venosus
In the fetus, the ductus venosus shunts approximately half of the blood flow of the umbilical vein directly to the inferior vena cava. Thus, it allows oxygenated blood from the placenta to bypass the liver. In conjunction with the other fetal shunts, the foramen ovale and ductus arteriosus, it...

Budd-Chiari syndrome
In medicine , Budd–Chiari syndrome is the clinical picture caused by occlusion of the hepatic veins. It presents with the classical triad of abdominal pain, ascites and hepatomegaly. Examples of occlusion include thrombosis of hepatic veins. The syndrome can be fulminant, acute, chronic, or...
