Percutaneous transhepatic cholangiography

Percutaneous transhepatic cholangiography (PTHC or PTC) or percutaneous hepatic cholangiogram is a radiologic technique used to visualize the anatomy of the biliary tract. A contrast medium is injected into a bile duct in the liver, after which X-rays are taken. It allows access to the biliary tree in cases where endoscopic retrograde cholangiopancreatography (ERCP) has been unsuccessful. Initially reported in 1937, the procedure became popular in 1952.
