Percutaneous Transumbilical Portal Vein Embolization in a Patient with a Ruptured Hepatocellular Carcinoma Supplied by the Portal Vein.
Summary of "Percutaneous Transumbilical Portal Vein Embolization in a Patient with a Ruptured Hepatocellular Carcinoma Supplied by the Portal Vein."
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 material-enhanced computed tomographic (CT) scan showed the presence of a large hypervascular tumor on portal venous phase as well as right hepatic vein thrombosis and hemoperitoneum that prevented portal vein embolization by the use of the percutaneous and transjugular transhepatic approach. The use of percutaneous transumbilical portal vein embolization can be an alternative option in this situation.

Medical and Biotech [MESH] Definitions
A short thick vein formed by union of the superior mesenteric vein and the splenic vein.
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.
Veins which return blood from the intestines; the inferior mesenteric vein empties into the splenic vein, the superior mesenteric vein joins the splenic vein to form the portal vein.
Diagnostic and therapeutic procedures that are invasive or surgical in nature, and require the expertise of a specially trained radiologist. In general, they are more invasive than diagnostic imaging but less invasive than major surgery. They often involve catheterization, fluoroscopy, or computed tomography. Some examples include percutaneous transhepatic cholangiography, percutaneous transthoracic biopsy, balloon angioplasty, and arterial embolization.
Portasystemic Shunt, Transjugular Intrahepatic
A type of surgical portasystemic shunt to reduce portal hypertension with associated complications of esophageal varices and ascites. It is performed percutaneously through the jugular vein and involves the creation of an intrahepatic shunt between the hepatic vein and portal vein. The channel is maintained by a metallic stent. The procedure can be performed in patients who have failed sclerotherapy and is an additional option to the surgical techniques of portocaval, mesocaval, and splenorenal shunts. It takes one to three hours to perform. (JAMA 1995;273(23):1824-30)
Usefulness of portography and contrast-enhanced computed tomography to predict the embolized area in percutaneous transhepatic portal vein embolization with absolute ethanol under temporary balloon occlusion.
PURPOSE: To assess the usefulness of portography and contrast-enhanced computed tomography (CECT) for predicting the embolized area after the first injection of absolute ethanol...
BACKGROUND: Portal vein ligation (PVL) and portal vein embolization (PVE) are used to induce hypertrophy of the future remnant liver before major liver resection. The aim of our study was to compare t...
Although transjugular intrahepatic portosystemic shunt (TIPS) placement is the standard procedure for the treatment of portal hypertension, it is often impossible to perform in patients with extrahepa...
We report a case of successful embolization of jejunal varices that were the cause of massive gastrointestinal bleeding from a choledochojejunostomy site, resulting from obstruction of the extrahepati...
PURPOSE: Portal vein embolization is performed to increase the future liver remnant before liver surgery in patients with liver malignancies. This study assesses the feasibility...
RATIONALE: Embolization blocks blood flow to part of an organ and/or tumor. Blocking the portal vein on one side of the liver may cause the opposite side of the liver to increase in size a...
OBJECTIVES: I. Evaluate the efficacy of a certain drug in preventing intestinal complications in patients with cirrhosis and high blood pressure in the hepatic portal vein. II. E...
