Portal biliopathy: a multitechnique imaging approach.
Summary of "Portal biliopathy: a multitechnique imaging approach."
Portal biliopathy (PB) is a disorder characterized by biliary ductal and gallbladder wall abnormalities seen in patients with extrahepatic portal vein obstruction. These abnormalities consist mainly of bile duct compression and tethering, stenoses, fibrotic strictures and dilatation of both extrahepatic and intrahepatic bile ducts, as well as gallbladder varices. In this pictorial essay, we describe the imaging findings of PB, which allow differentiation of this entity from other diseases that may have similar imaging findings including cholangiocarcinoma, extrinsic compression of the bile duct caused by metastatic adenopathy or sclerosing cholangitis.

Medical and Biotech [MESH] Definitions
The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.
Abnormal increase of resistance to blood flow within the hepatic PORTAL SYSTEM, frequently seen in LIVER CIRRHOSIS and conditions with obstruction of the PORTAL VEIN.
Esophageal And Gastric Varices
Dilated blood vessels in the ESOPHAGUS or GASTRIC FUNDUS that shunt blood from the portal circulation (PORTAL SYSTEM) to the systemic venous circulation. Often they are observed in individuals with portal hypertension (HYPERTENSION, PORTAL).
Portasystemic Shunt, Surgical
Surgical venous shunt between the portal and systemic circulation to effect decompression of the portal circulation. It is performed primarily in the treatment of bleeding esophageal varices resulting from portal hypertension. Types of shunt include portacaval, splenorenal, mesocaval, splenocaval, left gastric-caval (coronary-caval), portarenal, umbilicorenal, and umbilicocaval.
The venous pressure measured in the PORTAL VEIN.
Background: Portal biliopathy refers to abnormalities of the biliary tract developing in relation to portal hypertension. Portosystemic splenorenal or mesenterico-caval shunting is a safe and effectiv...
In portal hypertensive biliopathy (PHB) secondary to portal thrombosis, multiple factors can lead to symptoms and alteration of liver tests. The compression of the common bile duct (CBD) by peribiliar...
A 69-year-old Japanese man was admitted to our hospital because of acute cholangitis with biliary obstruction. The cause of obstruction was either compression by a portal cavernoma or cavernous transf...
We describe a case of a ruptured hepatocellular carcinoma supplied by the portal vein that was successfully treated with portal vein embolization via a percutaneous transumbilical approach. A contrast...
The purpose of this study is to test a new technology for obtaining x-ray images of your treatment fields when you are positioned on the treatment machine, to determine whether this new sy...
Investigate vasoactive medicators in portal hypertension on stored sera
We seek to determine if patient data entry, data entered based alerts, and data review in a secure patient portal may provide a sustainable approach to improve diabetic outcomes in a cost...
The aim of this study is to investigate the pathophysiological mechanisms underlying the formation of posthepatectomy ascites with a focus on the significance of changes in portal venous h...
The investigators will address the hypothesis that portal hypertension is mediated in part by bacterial or endotoxin translocation and the production of inflammatory mediators (tumor necro...
