It also has a caudate process (that is not tail-like shaped) arising from its right side, which provides surface continuity between the caudate lobe and the visceral surface of the anatomical right lobe of the liver. [2] The caudate process is a small elevation of the hepatic substance extending obliquely and laterally, from the lower extremity ...
It is formed by the union of the right hepatic duct (which drains bile from the right functional lobe of the liver) and the left hepatic duct (which drains bile from the left functional lobe of the liver). [3] The duct is about 3 cm long. [4] The common hepatic duct is about 6 mm in diameter in adults, with some variation. [5]
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.
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 .
Caudate (Latin for "tail") may refer to: Caudate nucleus; Caudate leaf shape; Caudate lobe of liver; Cauda equina; A salamander (which is any member of the order Caudata
In the axial plane, the caudate lobe should normally have a cross-section of less than 0.55 of the rest of the liver. [ 2 ] Other ultrasound studies have suggested hepatomegaly as being defined as a longitudinal axis > 15.5 cm at the hepatic midline, or > 16.0 cm at the midclavicular line .
When the patient is supine, and the liver observed inferiorly (as in a surgeon's perspective), the important structures demarcating its inferior aspect can be represented by a hepatic "H" figure. The right vertical limb of the "H" defines the left and right functional lobes, while the left vertical limb of the "H" defines the right and left ...
The front border of the liver has been lifted up (brown arrow). [1] Intrahepatic bile ducts compose the outflow system of exocrine bile product from the liver. They can be divided into: [2] Lobar ducts (right and left hepatic ducts) - stratified columnar epithelium.
