The portal vein in patients with cirrhosis is not an excessively inflammatory or hypercoagulable vascular bed, a prospective cohort study.

J Thromb Haemost 2022 Jun 23. Epub 2022 Jun 23.

Surgical Research Laboratory and Section of Hepatobiliary Surgery and Liver Transplantation, Department of Surgery, University of Groningen, University Medical Center Groningen, Groningen, the Netherlands.

Background: A hypercoagulable state is not associated with development of portal vein thrombosis in cirrhosis, as we previously demonstrated. However, some groups demonstrated elevated levels of inflammatory markers and activation of haemostasis in the portal vein (PV) compared to post-hepatic veins, but as the liver is involved in clearance of these markers we hypothesize that interpretation of these data is not straightforward.

Aim: To determine whether the PV has particular proinflammatory/hypercoagulable characteristics by comparing plasma sampled in the PV, hepatic vein (HV) and the systemic circulation. Read More

Porto-sinusoidal vascular disorder.

J Hepatol 2022 Jun 8. Epub 2022 Jun 8.

Department for Visceral Medicine and Surgery, Inselspital, Bern University Hospital, University of Bern, Switzerland; Department of Biomedical Research, University of Bern, Bern, Switzerland.

It is well established that portal hypertension (PH) can occur in the absence of cirrhosis, as reported in patients with immune disorders, infections and thrombophilia. However, similar histological abnormalities affecting primarly the hepatic sinusoidal and the (peri)portal vasculature have also been observed in patients without PH. Thus, the term porto-sinusoidal vascular disorder (PSVD) has been recently introduced to describe a group of vascular diseases of the liver featuring lesions encompassing the portal venules and sinusoids, irrespective of the absence or presence of portal hypertension.
