Progress on the Study and Practice of Venous Thromboembolism after Operation of Tumor

摘要

The incidence rate of venous thromboembolism (VTE) of patients after operation is very high. Many studies on VTE have been processed. The pathogenesis, dangerous factors and assessment method of VTE are summarized in this paper. Two theories of pathogenesis, theory of Virchow’s triad and theory of anoxia at the tip of venous valve, are introduced first. The main dangerous factors of VTE such as tumor, perioperative period are discussed then. The main assessment methods of VTE are introduced also. At last, some problems required to be studied deeper have been presented.
