Endothelial-to-mesenchymal transition: A targetable mechanism that contributes to portal vein thrombosis in cirrhosis Open
Background and Aims: Portal vein thrombosis (PVT) is a frequent complication of cirrhosis, yet its pathophysiology remains elusive. Unlike thrombosis in other vascular beds, anticoagulation often fails to completely recanalize PVT, highlig…

Transjugular Intrahepatic Portosystemic Shunt (TIPS) for Treatment of Bleeding from Cardiofundal and Ectopic Varices in Cirrhosis Open
Acute variceal bleeding in cirrhosis represents a critical clinical event that significantly impacts patient prognosis, with mortality rates increasing further after a second episode. This underscores the need for immediate intervention an…

Porto-sinusoidal vascular disorder in chronic HBV: A significant coexistence not to be overlooked Open
The new diagnostic criteria for porto-sinusoidal vascular disorder (PSVD) allow for coexistence with other liver diseases. The results of the present study highlight, for the first time, a non-negligible prevalence of chronic hepatitis B i…

Impact of SARS-CoV-2 pandemic on vascular liver diseases Open
Vascular liver diseases (VLD) are represented mainly by portosinusoidal vascular disease (PSVD), non-cirrhotic splanchnic vein thrombosis (SVT) and Budd Chiari syndrome (BCS). It is unknown whether patients with VLD constitute a high-risk …

Combination of Model for End‐Stage Liver Disease and Lactate Predicts Death in Patients Treated With Salvage Transjugular Intrahepatic Portosystemic Shunt for Refractory Variceal Bleeding Open
Background and Aims Data about the prognosis of salvage transjugular intrahepatic portosystemic shunt (TIPS) using covered stents for refractory variceal bleeding caused by portal hypertension are scarce. We aimed to assess survival and to…
