We present a case of a 75-year-old man with nephrotic syndrome and renal insufficiency caused by immune complex-mediated secondary membranoproliferative glomerulonephritis. He developed hepatic encephalopathy. A congenital portosystemic shunt was identified, indicating a diagnosis of membranoproliferative glomerulonephritis with noncirrhotic portosystemic shunt. Proteinuria resolved after shunt...
Kanaya, So-i. and Katoh, H. (1995) Long-term evaluation of distal splenorenal shunt with splenopancreatic and gastie disconnection. Surgery; 118." 29-35. Background: This study was aimed at evaluating advantages of distal splenorenal shunt (DSRS) with splenopancreatic and gastric disconnection (DSRS-SPGD) over DSRS with splenopancreatic disconnection (DSRS-SPD) and standard DSRS (S-DSRS). Metho...
In the last 20 years, understanding has evolved about what has become known as the 'hepatotrophic' concept. The hepatotrophic hypothesis holds that there are specific substances in the portal venous blood, not found in equal concentration in other kinds of blood, which are important for the maintenance of normal hepatic morphology, function, and the capacity for regeneration (Starzl & Terblanch...
Background and aims: Up to 60% of patients treated with transjugular intrahepatic portosystemic shunt (TIPS) require angioplasty or restenting during the first year of follow up because of TIPS dysfunction (stenosis of the intrahepatic shunt increasing the portal pressure gradient above the 12 mm Hg threshold). We hypothesised that in patients with TIPS stenosis, propranolol administration, by ...
A transjugular intrahepatic portosystemic shunt (TIPS) is an expandable metal stent inserted via the jugular vein that creates a shunt from the portal vein to the systemic circulation via an artificial communication through the liver. It is used to treat complications of portal hypertension. In addition to rescue treatment in variceal bleeding, TIPS can play an important role in prevention of r...
Abernethy malformation (AM) is a rare congenital anomaly in which the splanchnic blood bypasses the liver and drains directly into the systemic veins. It was first described by Abernethy in 1793 and has two types. Type I is characterized by a complete portosystemic shunt and an absence of a portal vein (consists of superior mesenteric and splenic veins), while Type II exhibits partial portosyst...
Congenital (spontaneous) intrahepatic portosystemic shunt is rare in the English literature. Most cases of portosystemic shunt occur after trauma, surgery, liver biopsy or as a result of chronic portal hypertension. Chronic shunting may result in encephalopathy, bleeding or hyperinsulinism. We report a case of an asymptomatic adult female with a presumed congenital intrahepatic portosystemic sh...
Purpose. Interventional treatment strategies for patients with encephalopathy due to splenorenal shunt remain controversial. Portosplenic blood flow separation by occluding the splenic vein could avoid the complication of severe portal hypertension, but it would require repeated reintervention due to recurrence of symptoms. This paper describes occlusion of the splenic vein using coil anchors a...
Portal cavernoma cholangiopathy (PCC) is defined as abnormalities in the extrahepatic biliary system including the cystic duct and gallbladder with or without abnormalities in the 1st and 2nd generation biliary ducts in a patient with portal cavernoma. Presence of a portal cavernoma, typical cholangiographic changes on endoscopic or magnetic resonance cholangiography and the absence of other ca...
