What is the PTC

Percutaneous transhepatic cholangiography and drainage (PTC) is an anterograde direct cholangiography method, which uses a special puncture needle to penetrate the intrahepatic bile duct through the skin under the supervision of X-ray television or B-ultrasound, and then directly infuses the contrast medium into the bile duct to make the intrahepatic and extrahepatic bile ducts develop rapidly. This METHOD can clearly show the condition of intrahepatic and extrahepatic BILE DUCT, the LESION LOCATION, extent, degree and nature, which is beneficial to the diagnosis and differential diagnosis of Biliary duct diseases, especially jaundice.
