Percutaneous transhepatic cholangiogram - Risks

Alternative Names

PTCA; Cholangiogram - PTCA

What the risks are:

There is a slight chance of an allergic reaction to the contrast medium (iodine).

There is a slight chance of excessive blood loss, blood poisoning (sepsis), and inflammation of the bile ducts.

Special considerations:

This test has been mostly replaced by an endoscopic retrograde cholangiopancreatography (ERCP) test. A PTCA may be done if an ERCP test cannot be performed or has failed.

A magnetic resonance cholangiopancreatography (MRCP) is a newer, noninvasive imaging method, based on MRI. It provides similar views of the bile ducts, but is not always possible to perform.
