Abstract:

BACKGROUND: In recent years, the incidence of venous thromboembolism has increased yearly. Some studies have found that neutrophil extracellular traps participate in the initiation and growth stages of thrombosis, and have close relationship with endothelial cells, platelets and coagulation pathways embolism.

OBJECTIVE: To explore the relationship between neutrophil extracellular traps and venous thromboembolism, and to find a new direction in the diagnosis and treatment of venous thromboembolism.
METHODS: Databases of WanFang, CNKI, VIP, PubMed, Web of Science and Medline were searched with the keywords of “neutrophil extracellular traps, venous thromboembolism, deep vein thrombosis, pulmonary embolism” in Chinese and “NETs, VTE, DVT, PE” in English for the literature concerning neutrophil extracellular traps and venous thromboembolism published from 2004 to March 2018. The types of literature included journal article, conference literature, dissertation and review.
RESULTS AND CONCLUSION: Initially 1 226 articles were retrieved involving 1 094 English and 132 Chinese articles, and finally 50 eligible articles were enrolled for summarization based on the inclusion and exclusion criteria. The formation of a neutrophil extracellular trap is a cascade cell death program called NETosis, which is a cell death mode that is different from apoptosis and necrosis. The neutrophil extracellular trap is involved in the initiation and growth stages of thrombosis. Activation of endothelial cells and release of Weibel-Palade bodies play an important role in the initial stage of thrombosis. The neutrophil extracellular trap serves as a scaffold for platelet adhesion and aggregation. The Neutrophil extracellular trap also participates in the coagulation process via endogenous and exogenous pathways.
