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...

The creation of transjugular intrahepatic portosystemic shunt (TIPS) is a widely performed technique to relieve portal hypertension, and to manage recurrent variceal bleeding and refractory ascites in patients where medical and/or endoscopic treatments have failed. However, portosystemic shunt creation can be challenging in the presence of chronic portal vein occlusion. In this case report, we ...

Variceal bleeding from enterostomy site is an unusual complication of portal hypertension. The bleeding, however, is often recurrent and may be fatal. The hemorrhage can be managed with local measures in most patients, but when these fail, surgical interventions or portosystemic shunt may be required. Herein, we report a case in which recurrent bleeding from stomal varices, developed after a co...

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...

Transjugular intrahepatic portosystemic shunt (TIPS) is an interventional radiology technique that has shown a 90% success rate to decompress the portal circulation. As a non-surgical intervention, without requirement for anesthesia and very low procedure-related mortality, TIPS is applicable to severe cirrhotic patients, who are otherwise untreatable, for example, nonsurgical candidates. TIPS ...

BACKGROUND Recent studies have shown the presence of vascular endothelial growth factor (VEGF)-dependent splanchnic angiogenesis in experimental models of portal hypertension, and the role of such neovascularisation on the development of both portosystemic collaterals and hyperdynamic splanchnic circulation. However, the mechanisms modulating angiogenesis in portal hypertension are unknown. Exp...
