Inflammasome is a group of polyprotein complexes located in the cytoplasm, its activation can induce the maturation and release of proinflammatory cytokines IL-1β and IL-18, and promote the early atherosclerosis. In the recent years, it is found that the inflammasome is activated in thrombotic deseases, moveover, the activated inflammasome and its activation induced cytokines promote the occurrence and development of thrombolic deseases, and show the unfavaourable effect on prognosis. With further exploration on the mechanisms of thrombotic diseases, the relationship between the inflammasome and thrombotic diseases increasingly become a hot spot of research. This review focuses on the action mechanisms of inflammasome in thrombotic diseases.
