Percutaneous Transhepatic Cholangiogram

Also known as: PTC, PTHC, PTCA, percutaneous transhepatic cholangiograghy.

What is percutaneous transhepatic cholangiogram?

Percutaneous transhepatic cholangiogram is a procedure used to look for problems in the bile ducts that transport bile from the liver to the small intestine or gallbladder. It is performed with an X-ray.

What happens during the procedure?

The patient lies on a table while an X-ray is focused on the bile ducts. A needle is used to inject contrast dye into the bile ducts, which allows the bile ducts to be seen more clearly while more X-rays are taken.  

Is any special preparation needed?

No special preparations are needed for the procedure.

What are the risk factors?

Bleeding, infection, blood poisoning, inflammation or damage to the bile ducts or surrounding organs are possible risks of percutaneous transhepatic cholangiogram.
