title: Extravasation of contrast material due to rupture of the intrahepatic duct: eight additional cases.
abstract: We have reported eight additional cases of contrast extravasation due to rupture of the intrahepatic duct. Although this phenomenon is usually caused by blind instrumentation of the biliary ducts, it can also result from excessive pressure during injection of contrast material. Undetected extravasation can lead to transient hemorrhage, abscess formation, hematobilia, intraductal obstruction, and cholangitis. Rupture can best be prevented by increased care on the part of the surgeon.
