Abstract
Purpose of Review
Portal vein thromboses occur in patients with cirrhosis, including those awaiting liver transplant, and uncertainty exists regarding its prognosis, workup, and optimal management.
Recent Findings
The prevalence of PVT is higher in those with more severe liver disease (24% vs 14% for Child-Pugh B/C vs A, respectively). PVT, especially those with complete occlusion, is associated with mortality and graft loss in liver transplant recipients. Increasing data on direct oral anticoagulant (DOAC) use in cirrhosis and specifically for use in patients with PVT provides physicians and patients with more appealing anticoagulation options. In addition to observation and anticoagulation, there is an emerging role of transjugular intrahepatic porto-systemic (TIPS) shunt for recanalization of the portal vein in certain patients, with prospective single-center study demonstrating 98–100% efficacy in those with complete occlusion compared to a lower rate of patency with medical therapy alone (13%).
Summary
Due to the complexities involved in assessing and managing PVTs in cirrhosis based on individual patient factors, a multidisciplinary approach with hepatologists, hematologists, interventional radiologists, and transplant surgeons is strongly recommended for patients who are transplant candidates, have recurrent thromboses or complex anatomy, and may be considered in any patient with cirrhosis.
