cystic ovarian degeneration (disease)
includes cystic follicle, luteal cyst, cystic corpus luteum (above). A major cause of reproductive failure and economic loss in dairy cattle. Results in an increase in days open in the post partum period and an increase in culling rates for reproductive failure. It occurs when a mature follicle fails to ovulate as a result of exogenous or endogenous disruption of the hypothalamo-hypophyseal-ovarian axis; the resultant anovulatory follicular structure can regress or persist as a follicular cyst or a luteal cyst depending on its structural characteristics. Diagnosis and differentiation of follicular cysts and luteal cysts has traditionally been by rectal palpation but ultrasound examination is more accurate.

A more serious situation may arise when a gallstone passes through the cystic duct into the common bile duct.
It is thought that gallstone pain results from a blockage of the cystic duct by a stone.
2-3) It occurs when the common hepatic duct becomes obstructed due to extrinsic compression from an impacted gallstone in the cystic duct or the neck of the gallbladder.
From the surgeons' point of view, the Visu- Loc clip easily ligates the most robust cystic duct.
4) The discharge from the fistula may be purulent and mucoid if the cystic duct is obstructed by a stone.
The first of these is where the gallbladder has its own mesentery; the second occurs when the cystic duct and artery have a mesentery, and the gallbladder is free within the peritoneal cavity.
