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. Interlobar ducts (between the main hepatic ducts and the interlobular ducts) - pseudostratified columnar epithelium.
Transjugular intrahepatic portosystemic shunts are typically placed by an interventional radiologist under fluoroscopic guidance. [9] Access to the liver is gained, as the name 'transjugular' suggests, via the internal jugular vein in the neck .
The bile duct is some 6–8 cm long, and normally up to 8 mm in diameter. [4]Its proximal supraduodenal part is situated within the free edge of the lesser omentum.Its middle retroduodenal part is oriented inferiorly and right-ward, and is situated posterior to the first part of the duodenum, and anterior to the inferior vena cava.
The common hepatic duct is the first part of the biliary tract. [2] 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).
Micrograph of an intrahepatic, i.e. in the liver, cholangiocarcinoma (right of image); benign hepatocytes are seen (left of image). Histologically, this is a cholangiocarcinoma as (1) atypical bile duct-like cells (left of image) extend from the tumor in an interlobular septum (the normal anatomical location of bile ducts), and (2) the tumor ...
Intrahepatic cholestasis of pregnancy (ICP), also known as obstetric cholestasis, cholestasis of pregnancy, jaundice of pregnancy, and prurigo gravidarum, [1] is a medical condition in which cholestasis occurs during pregnancy. [2] It typically presents with itching and can lead to complications for both mother and fetus. [2]
A portosystemic shunt or portasystemic shunt (medical subject heading term; PSS), also known as a liver shunt, is a bypass of the liver by the body's circulatory system.It can be either a congenital (present at birth) or acquired condition and occurs in humans as well as in other species of animals.
Type V: Cystic dilatation of intrahepatic biliary ducts without extrahepatic duct disease. The presence of multiple saccular or cystic dilations of the intrahepatic ducts is known as Caroli's disease. [4] Type VI: An isolated cyst of the cystic duct is an extremely rare lesion. Only single case reports are documented in the literature.
