Pediatric Percutaneous Transhepatic Cholangiogram (PTC)

What is a percutaneous transhepatic cholangiogram (PTC)?

A percutaneous transhepatic cholangiogram, or PTC, is an X-ray of the bile ducts (also called the biliary ducts). Radiologists and other doctors use the images to determine if the ducts are underdeveloped or blocked. If the ducts are blocked, the doctor may place a drainage catheter. PTC is sometimes performed at the same time as a liver biopsy. Bile is a substance that helps digest fats. It is made in the liver and stored in the gallbladder. After meals, it is excreted into the intestines via the bile ducts.
