ABSTRACT
Introduction
Liver cirrhosis is accompanied by several hemostatic alterations, which contribute to the current theory of “rebalanced hemostasis.” Splanchnic vein thrombosis (SVT) is a frequent complication of liver cirrhosis (17–26% of the cirrhotic patients), and liver cirrhosis is a common risk factor for SVT (24–28% of SVT cases).
Areas covered
This narrative review aims to describe the current state of the art on the anticoagulant treatment of cirrhotic SVT, with a particular focus on the possible role of the direct oral anticoagulants (DOACs) and recent guidelines on this topic.
Expert opinion
Early anticoagulant therapy is recommended in cirrhotic patients with acute SVT, to obtain vessel recanalization and decrease the rates of portal hypertension-related complications. Gastroesophageal varices do not represent a contraindication to anticoagulation, if adequate prophylaxis of variceal bleeding is established, and varices band ligation can be safely performed without the need to stop the anticoagulant treatment. The conventional treatment of cirrhotic SVT consisted of low molecular weight heparin, as initial treatment of choice, eventually followed by vitamin K antagonists, but the DOACs can be considered as a reasonable alternative in patients with compensated liver cirrhosis.
Article highlights
Splanchnic vein thrombosis (SVT) occurs frequently in patients with liver cirrhosis.
Early anticoagulation is recommended in cirrhotic patients with acute SVT. A cautious risk-benefit evaluation is required.
The use of direct oral anticoagulants (DOACs) in cirrhotic patients is slowly increasing in clinical practice.
Emerging evidence suggests the DOACs as a reasonable alternative in patients with compensated liver cirrhosis.
