Percutaneous transhepatic cholangiography (PTHC or PTC) or percutaneous hepatic cholangiogram is a radiological technique used to visualize the anatomy of the biliary tract. A contrast medium is injected into a bile duct in the liver, after which X-rays are taken.


Percutaneous transhepatic cholangiography (PTC) is a radiographic technique employed in visualization of the biliary tree and can be used as the first step in a number of percutaneous biliary interventions (e.g. percutaneous transhepatic biliary ...


A percutaneous transhepatic cholangiogram (PTC) is an x-ray of the bile ducts. These are the tubes that carry bile from the liver to the gallbladder and small intestine.


Percutaneous Transhepatic Cholangiography Definition Percutaneous transhepatic cholangiography (PTHC) is an x-ray test used to identify obstructions either in the liver or bile ducts that slow or stop the flow of bile from the liver to the digestive system. Purpose Because the liver and bile ducts are not normally seen on x rays, the doctor injects the ...


Transhepatic cholangiography in patients with suspected biliary disease and nondilated intrahepatic bile ducts. Gastrointest Radiol 1991; 16:193. Cozzi G, Severini A, Civelli E, et al. Percutaneous transhepatic biliary drainage in the management of postsurgical biliary leaks in patients with nondilated intrahepatic bile ducts.


In most cases, percutaneous transhepatic cholangiography (PTC) can be performed via the right midaxillary approach, though a subxiphoid approach is occasionally needed. Some patients (eg, those with a cholangiocarcinoma involving the hilum and central right and left hepatic ducts) may require ...


Percutaneous Transhepatic Cholangiography. Compared with ERCP, percutaneous transhepatic cholangiography (PTC) is time consuming, more involved, and likely more stressful for a patient. It is usually reserved for patients in whom anatomic considerations preclude safe ERCP, such as in the case of an impossible ampullary cannulation.


Abstract. This is an evaluation of percutaneous transhepatic cholangiography, a technique of over eight years' standing, previously considered by many authorities as both unrewarding and dangerous.


A transhepatic cholangiography is an invasive imaging study that shows the bile ducts in the liver. During this procedure, a contrast medium is injected into one of the bile ducts in the liver and x-rays are then taken. The contrast is injected by a needle that is placed into one of the bile ducts through the skin and liver.


A percutaneous transhepatic cholangiogram, or PTC, is an X-ray of the bile ducts (also called the biliary ducts). Radiologists and other doctors use the images to determine if the ducts are underdeveloped or blocked. If the ducts are blocked, the doctor may place a drainage catheter. PTC is sometimes performed at the same time as a liver biopsy.
