Hepatobiliary imaging to demonstrate drainage patterns in a patient with an indwelling hepatic catheter

The presence of normal biliary flow was established in a patient with an indwelling hepatic catheter placed to drain an intrahepatic cyst cavity with the use of sequential hepatobiliary scintiscans. In the initial study drainage was demonstrated from the indwelling catheter; when the catheter was clamped, drainage was observed in the native biliary system. Serial biliary scintigraphy not only confirmed the patency of the hepatobiliary system, but served as a guide in the removal of the intrahepatic catheter.
