Establishment and application of animal models for portal vein thrombosis / 临床肝胆病杂志

Portal vein thrombosis （PVT） refers to thromboembolism that occurs in the extrahepatic main portal vein and/or intrahepatic portal vein branches. PVT is the result of the combined effect of multiple factors， but its pathogenesis remains unclear. Animal models are an important method for exploring the pathophysiological mechanism of PVT. Based on the different species of animals， this article reviews the existing animal models of PVT in terms of modeling methods， principles， advantages and disadvantages， and application.
