Cleveland Clinic Journal of MedicineWhat are the Management Considerations for Venous Thromboembolic Events in Patients with Cirrhosis?

His history suggests that the DVT was provoked by immobility secondary to pneumonia.

In patients with cirrhosis, the management of venous thromboembolic events (VTE) presents a unique set of challenges, owing to altered hemostatic mechanisms that predispose them to both bleeding and thrombotic risks. The case of a 61-year-old with cirrhosis and deep vein thrombosis (DVT) underscores the critical considerations for treating such patients effectively. This article synthesizes current evidence and expert recommendations to guide physicians in the nuanced management of VTE in the context of liver disease, highlighting the importance of individualized care and the need for further research.

Key Points

• Direct oral anticoagulants (DOACs) or low-molecular-weight heparin (LMWH) are recommended for the treatment of DVT in patients with cirrhosis, with choices guided by patient preference, cost, and adherence requirements.
• Cirrhosis leads to a “rebalanced” hemostatic state due to alterations in pro- and antihemostatic pathways, challenging the traditional view that these patients are only at increased bleeding risk.
• Patients with cirrhosis have a significantly higher risk of developing VTE compared to controls, with a systematic review and meta-analysis showing an odds ratio (OR) of 1.7.
• Clinical scoring systems like the Padua Prediction Score and the IMPROVE risk score can help predict VTE risk in cirrhotic patients, though limitations exist due to a lack of prospective validation specifically for this population.
• Despite the increased VTE risk, evidence supporting VTE prophylaxis in cirrhosis is limited, with no randomized controlled trials comparing outcomes. However, professional guidelines recommend standard anticoagulation prophylaxis in hospitalized patients with cirrhosis.
• The European Association for the Study of the Liver (EASL) and the FDA provide cautious recommendations on the use of DOACs and traditional anticoagulants in cirrhotic patients, emphasizing individualized treatment approaches based on the severity of liver disease and potential risks.
• Retrospective data suggest DOACs may have comparable safety and efficacy to traditional anticoagulants in cirrhotic patients, with specific agents like edoxaban showing promise in treating portal vein thrombosis.
• Prospective studies are needed to better define the safety, efficacy, and optimal management strategies for anticoagulation in patients with cirrhosis, given the complex interplay of factors affecting their risk of VTE and bleeding.

In this 2023 study from Cureus, researchers found a PVT prevalence of 17.2% in cirrhotic patients, with a higher prevalence of acute PVT than chronic PVT.
