Cystic Duct Definition
What is Cystic Duct? The cystic duct is a tubular structure that is a component of the biliary duct system. It connects the common hepatic duct to the common bile duct, and transports bile from the gallbladder.
It is also known as Conduit cystique in French and Ductus cysticus in Latin.
Cystic Duct Function
It connects the top part of the neck of the gallbladder to the common hepatic duct. Then, it joins to the cystic duct common bile duct, which joins the pancreatic duct before being it releases into the duodenum.
As it is responsible for transporting bile between ducts, it is vital to the process of digestion.
Cystic Duct Anatomy
The cystic duct is around 4 cm long in an average adult. It is located between the common bile duct and the gallbladder. It is generally found adjacent to the cystic artery.
In healthy adults, conducting the smallest probe through the duct is impossible, due to the singular arrangement of its mucous lining and its double curved course. The cystic duct has a terminal portion and it is located before the portal vein. The cystic artery is placed over and rear to the cystic duct, as well as the portal vein that is located rear to it, at the meeting point of the hepatic and cystic ducts.
The cystic bile duct has 3 primary variations, which include:
Parallel Cystic Duct Course
It runs parallel to the Common Hepatic Duct for 2 cm at least.
Medial cystic duct insertion
It runs into the left side of the Common Hepatic Duct, and not the right.
Low Cystic Duct Insertion
It runs into the distal-third of the Common Hepatic Duct.
Cystic Duct Problems and Disorders
The cystic duct can be affected by various conditions, which include:
