BACKGROUND The liver has an enormous capacity to regenerate itself. The aim of this study was to evaluate whether the regeneration is due to hypertrophy or hyperplasia of the remnant liver after extended resection and whether a portosystemic shunt is beneficial. MATERIAL AND METHODS An extended left hemihepatectomy was performed in 25 pigs, and in 14 after performing a portosystemic shunt. Du...

CASE A 73 year old female had been diagnosed as primary biliary cirrhosis and Sjögren's syndrome since the age of 50. With persisting hyperammonemia, the patient was admitted on several occasions for the management of hepatic encephalopathy. Computed tomography (CT) scan and magnetic resonance imaging (MRI) of the abdomen showed varices in the splenic hilar region and a splenorenal shunt. A bal...

Background. The purpose of this study was to evaluate the safety and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) placement in the management of portal hypertension in noncirrhotic patients with portal cavernoma. Methods. We conducted a single institution retrospective analysis of 15 noncirrhotic patients with portal cavernoma treated with TIPS placement. 15 patients (4 wome...

The usefulness of selective transplenic decompression of oesophageal varices by distal splenorenal shunt and splenocaval shunt was evaluated in the control of gastrointestinal haemorrhage in patients with portal hypertension of varied aetiology. (Decompression was successful in 69 out of 78 cases.) It was shown that it is superior to total portosystemic shunts, as the incidence of encephalopath...

The possible existence of the same pattern of porto-caval connection in dogs having a single congenital portosystemic shunt (CPSS) and in dogs having multiple acquired portosystemic shunt (MAPSS) secondary to portal hypertension (PH) was evaluated. Retrospective evaluation of all CT examinations of patients having portosystemic shunt (PSS) was performed in a 4-year time period. All anomalous po...

Management of clinically important sequelae of portal hypertension, such as variceal bleeding and ascites, may involve a combination of medical, endoscopic, surgical, and interventional approaches and procedures. Although clinically significant esophageal and rectal varices are typically visible endoscopically, ectopic varices may require multiplanar portal venous phase computed tomography or m...

The bleeding of peristomal varices due to a portosystemic shunt is rare but potentially life-threatening in cirrhotic patients with portal hypertension. The scarce case reports in the literature recommend transjugular intrahepatic portosystemic shunt (TIPS) to prevent further bleeding. We report on a 72-year-old man who was referred to our hospital because of life-threatening bleeding from peri...

OBJECTIVES The most serious, life-threatening complication after living-donor liver transplant is a hepatic arterial thrombosis. Although possible therapies for acute hepatic arterial thrombosis include revascularization to salvage the graft, or retransplant, these may be difficult to perform owing to technical aspects and donor shortages. Previously, we reported the usefulness of partial porta...

A dialysis patient with hyperammonaemia: inferior mesenteric-caval shunt as a cause of portal-systemic encephalopathy Sir, We report here a rare case of portal-systemic encephalop-athy with occasional loss of consciousness caused by an inferior mesenteric-caval shunt via the internal iliac vein in a peritoneal dialysis (PD) patient who was switched to haemodialysis (HD). A 71-year-old man with ...

OBJECTIVE To systematically evaluate the effectiveness of devascularization and shunt on patients with portal hypertension. METHODS Relevant studies compared devascularization and shunt for the treatment of portal hypertension were identified searching the PubMed, Embase, Elsevier, CNKI (China National Knowledge Infrastructure) database and Cochrane Trial Register searches until December 2013...
