What is the cystic duct?
Listen to pronunciation. (SIS-tik dukt) A tube that carries bile from the gall bladder. It joins the common hepatic duct to form the common bile duct.
What is unusual about the cystic duct?
Cystic duct stones represent a unique clinical challenge for several reasons. First, selective wire entry into the cystic duct can be challenging since in some patients the wire preferably enters the common hepatic duct. Second, the cystic duct is tortuous. Third, the cystic duct is often smaller than the stone.
What forms the cystic duct?
The right and left hepatic ducts exit the liver and then join together to form the common hepatic duct. The common hepatic duct and the cystic duct join to form the common bile duct. The cystic duct connects the gallbladder (a small organ that stores bile) to the common bile duct.
What is the location of cystic duct?
The cystic duct (arrows) connects the gallbladder to the extrahepatic bile duct and usually enters from the right approximately halfway between the porta hepatis and the ampulla of Vater. It also contains the valves of Heister.
Where is cystic duct located?
gallbladder
The cystic duct connects the top of the gallbladder’s neck to the common hepatic duct. It then joins the common bile duct, which meets pancreatic duct before it empties into the duodenum. In the average adult, the cystic duct measures four centimeters in length. The gallbladder stores bile produced in the liver.
What is diameter of cystic duct?
The cystic duct is about 3 mm in diameter and about 2 to 4 cm long. If surgeons are unaware of a short duct, they may accidentally enter the common bile duct.
Where is the cystic duct located?
How is the cystic duct depicted on imaging studies?
The cystic duct can be depicted with a variety of imaging modalities but is optimally visualized with direct cholangiography or magnetic resonance cholangiopancreatography. Nevertheless, unrecognized anatomic variants of the cystic duct may cause confusion on imaging studies and complicate subsequen …
What is the size of the cystic duct?
The cystic duct is approximately 2-3 cm long and 2-3 mm in diameter. The cystic artery (branch of right hepatic artery) can often travel behind the cystic duct to supply the gallbladder. There are three main variations of the cystic duct 3:
Are there unrecognized anatomic variants of the cystic duct?
Nevertheless, unrecognized anatomic variants of the cystic duct may cause confusion on imaging studies and complicate subsequent surgical, endoscopic, and percutaneous procedures.
Is the junction of the cystic and common hepatic ducts adequately visualized?
Knowledge of the junction of the cystic and common hepatic duct is essential for endoscopic management of biliary tract disease. The cystic and common hepatic ducts were evaluated retrospectively in cholangiograms obtained for a variety of indications in 524 persons. The cysticohepatic junction was adequately visualized in 70%.
