title: Sonographic evaluation of the common bile duct in cats.
abstract: Ultrasound is an excellent imaging tool in the evaluation of the biliary tract in cats. Extrahepatic obstruction could be diagnosed by the presence of dilated common bile duct (CBD), which was measured ventral to the portal vein in the porta hepatis. At this level, the diameter of the CBD in 6 healthy cats and in 22 cats with nonsurgical jaundice was < or = 4 mm. Six of 7 cats with a CBD > 5 mm had extrahepatic biliary obstruction.
