Abstract
Percutaneous transhepatic cholangiography is a useful imaging technique during biliary
evaluation and interventions. However, contrast cholangiography alone provides limited
information on the nature, quality, or severity of potentially treatable biliary conditions.
In this case report, transhepatic intravascular ultrasound is utilized to perform
intraductal ultrasonography during complex biliary reconstruction for the evaluation
of indeterminate biliary obstruction and management of intrastent stenosis.
