What is Percutaneous Transhepatic Cholangiography?
Percutaneous Transhepatic Cholangiography (PTC) is a minimally invasive diagnostic technique used to visualize the biliary tree. In pediatrics, it serves as an important tool when evaluating suspected biliary tract obstructions or anomalies. By inserting a needle through the skin and liver into the bile duct, a contrast dye is injected to allow X-ray imaging of the biliary structures.
