Objectives:
Portal vein thrombosis seems to be dependent on local hypercoagulation and venous stasis; data regarding endothelial damage are lacking.
Methods:
von Willebrad factor, a marker of endothelial damage/perturbation, factor VIII, and lipopolysaccharides (LPS) were studied in the portal and systemic circulation of 20 cirrhotic patients undergoing transjugular intrahepatic portosystemic procedure.
Results:
von Willebrad factor, factor VIII, and LPS were higher in the portal compared with systemic circulation, with a significant correlation between LPS and the other 2 variables.
Discussion:
Endothelial damage and hypercoagulation coexist in the portal tree of patients with cirrhosis, and both could contribute to portal vein thrombosis. LPS may be a potential trigger of endothelial damage.

Hepatic Portal System
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is responsible...
