Microparticles (MPs) are small (0.1-1.0 μm) membrane vesicles constitutively released from the surface of cells after activation and apoptosis. The clinical research on MPs is hampered by the limitations of the currently available detection methods. A correlation between MPs and venous thromboembolism (VTE) has been observed. The effects of MPs on thrombogenesis involve the exposure of phosphatidylserine, the vehiculation of tissue factor, and MP-induced intercellular cross-talk between inflammation and coagulation. This review will focus on the potential role of plasma MPs as biomarkers in detecting acute unprovoked VTE, predicting VTE occurrence in high-risk situations (mainly cancer), and ultimately, we will discuss currently available studies on the prognostic role of MPs to guide primary and secondary VTE prevention protocols.

Abstract
Microparticles (MPs) are small (0.1-1.0 μm) membrane vesicles constitutively released from the surface of cells after activation and apoptosis. The clinical research on MPs is hampered by the limitations of the currently available detection methods. A correlation between MPs and venous thromboembolism (VTE) has been observed. The effects of MPs on thrombogenesis involve the exposure of phosphatidylserine, the vehiculation of tissue factor, and MP-induced intercellular cross-talk between inflammation and coagulation. This review will focus on the potential role of plasma MPs as biomarkers in detecting acute unprovoked VTE, predicting VTE occurrence in high-risk situations (mainly cancer), and ultimately, we will discuss currently available studies on the prognostic role of MPs to guide primary and secondary VTE prevention protocols.
