Percutaneous transhepatic cholangiography (PTC) is a diagnostic procedure that uses X-ray imaging to visualize the bile ducts, which are the small tubes that transport bile from the liver to the small intestine. The procedure is typically used to diagnose and treat problems with the bile ducts, such as blockages, infections, or tumors.
The procedure is performed under local anesthesia, and it typically takes about an hour to complete. During the procedure, a thin needle is inserted through the skin and into the liver. A small tube (catheter) is then passed through the needle and into the bile ducts. A special dye (contrast material) is injected through the catheter, which allows the bile ducts to be seen on X-ray images.
The procedure is performed under the guidance of X-ray imaging and fluoroscopy, which is a type of real-time X-ray imaging. This allows the physician to see the bile ducts and any abnormalities or blockages in them.
After the procedure, the patient will be monitored for any complications and will typically need to stay in the hospital for a few hours for recovery. The patient may experience some discomfort or pain at the site of the needle insertion, but this usually goes away quickly.
PTC can be used to diagnose a variety of bile duct problems, including blockages, infections, and tumors. It can also be used to treat some of these problems, such as by removing a blockage or placing a stent to keep the bile duct open.
One of the main advantages of PTC is its ability to diagnose problems in the bile ducts that may not be visible on other imaging tests, such as CT scans or MRI. PTC can also be used to guide other procedures, such as the removal of a bile duct tumor or the placement of a stent to keep the bile duct open.
However, PTC is not without its risks. The procedure carries a small risk of bleeding, infection, or injury to the liver or bile ducts. Additionally, the contrast material used during the procedure can cause allergic reactions in some people.
