Percutaneous dislodgement of an impacted cystic duct stone.

An obstructing cystic duct stone was dislodged with an angiographic catheter and guidewire via a percutaneous cholecystostomy tract in a mildly sedated patient. After brief stenting of the cystic duct, the patient remained asymptomatic with internal bile drainage. When endoscopic negotiation of the cystic duct is difficult, an impacted cystic duct stone can sometimes be dislodged with standard angiographic techniques.
