cystic duct n.
The duct that leads from the gallbladder and joins the hepatic duct to form the common bile duct.
The effects of obstruction are much less important when the cystic duct is closed.
By passing a canula into this and ligaturing, the cystic duct may be injected.
Just at the bend of the cystic duct, near its origin, is the point where arrest of a calculus is most likely to take place.
Such is the state of the case when a calculus enters and is arrested in the cystic duct.
The cystic duct develops as the result of a similar increase in length of the cystic diverticulum.
The separate hepatic ducts then unite successively with the cystic duct.
When the cystic duct is obstructed the contents of the gall-bladder increase, and become ultimately sero-purulent (dropsy).
