Research progress on mechanical prevention of venous thromboembolism

With the increasement of the morbidity and mortality of venous thromboembolism (VTE), and the increasement of social burden, medical staff pay more attention to VTE and improve their awareness of it.As a preventable disease, the prevention of VTE is especially important.VTE prevention mainly includes drug prevention and mechanical prevention.However, drug prevention may cause the risk of bleeding, which limits the application of drug prevention.Mechanical prevention has extensive applications due to non-invasiveness, high patient compliance, fewer complications, simpleness and convenience, and excellent effectiveness.This article mainly summarizes the methods, advantages and disadvantages of mechanical prevention.
