Classification and Management of Portal Vein Thrombosis in Cirrhotic Patients: A Narrative Review

Portal vein thrombosis (PVT) poses significant therapeutic challenges due to its complex pathophysiology and diverse clinical presentations. Recent advancements have spurred the development of new therapeutic approaches to enhance treatment efficacy and safety. This review synthesized emerging therapies for PVT based on a comprehensive literature search across major databases such as PubMed, EMBASE, and Web of Science, among others, focusing on studies published in the last decade. Anticoagulation therapy, particularly with novel oral anticoagulants (NOACs), emerged as beneficial in personalized treatment regimens. Innovative surgical techniques and improved risk stratification methods were identified as crucial in the perioperative management of PVT. Additionally, advances in cell therapy and medical treatments for hepatocellular carcinoma in the context of PVT were explored. Promising outcomes were observed with modalities such as Yttrium 90 and liver transplantation combined with thrombectomy, particularly in complex PVT cases associated with hepatocellular carcinoma, albeit on a limited scale. The reviewed literature indicates a shift towards individualized treatment approaches for PVT, integrating novel anticoagulants, refined risk assessment tools, and tailored interventional strategies. While these emerging therapies show potential for enhanced efficacy and safety, further research is essential to validate findings across broader patient populations and establish standardized treatment protocols.
