Transient portal vein thrombosis in liver cirrhosis

Abstract

Abstract In real-world clinical practice, the acceptance of anticoagulation therapy in the management of portal vein thrombosis (PVT) in patients with cirrhosis is limited by the fear of an increased bleeding risk. Additionally, accumulating evidence indicates that spontaneous recanalization of PVT may occur in the absence of antithrombotic treatment. Therefore, risk stratification based on outcomes in such patients is crucial for determining a therapeutic strategy. In this paper, we draw attention to the distinct clinical entity, “transient PVT” by introducing two cases with PVT that spontaneously recanalized in the absence of antithrombotic treatment. We reviewed the available data regarding the probability of and predictors for spontaneous recanalization of PVT. Available data suggest singling out transient thrombosis in the natural history of PVT in patients with cirrhosis because of its prognostic and management implications.
