What is PTC? Percutaneous transhepatic cholangiography, or PTC, is a way of examining the bile duct system in the liver. This procedure is done under local anesthesia by a radiologist. During the exam, a thin needle is inserted through the skin (percutaneous) and through the liver (transhepatic) into a bile duct. Then dye is injected, and the bile duct system is outlined on x-rays (cholangiography).
