[Exploration of pathogenesis and clinical diagnosis and treatment for portal vein thrombosis formation]

Portal vein thrombosis (PVT) refers to the thrombosis of the main portal vein and/or branches, with or without mesenteric vein and splenic vein thrombosis, and is the most common cause of extrahepatic portal vein obstruction. It is latent under chronic conditions and is often detected accidentally during physical examinations or liver cancer screenings. Notably, the understanding of PVT management is still limited, both at home and abroad. Therefore, the purpose of this article is to provide a reference for clinical diagnosis and treatment of PVT formation by summarizing the basis and standards for clinical diagnosis and treatment based on representative research with a large sample size and new perspectives with recent guidelines and consensus.
