Percutaneous Transhepatic Cholangiography PTCA

Percutaneous Transhepatic Cholangiography (PTCA)

A percutaneous transhepatic cholangiogram (PTCA), is an X-ray examination of the bile ducts. Bile ducts transport bile from the liver to the small intestine and gallbladder. Bile helps the body break down fats. A needle is inserted through the skin into the liver. Dyes in the needle are injected into the bile ducts to help the bile ducts to be clearly seen on the X-ray. Additional X-rays are done as the dye flows in the bile ducts to the small intestine. The X-rays can show if the bile ducts are obstructed. Bile duct blockage can cause a yellow coloring to the skin (jaundice) or infection of the liver, pancreas and gallbladder.
