Abstract: Pregnancy associated venous thromboembolism (PA-VTE) refers to venous thromboembolism in pregnancy and puerperium. PA-VTE can occur at different stages of pregnancy, with the highest risk in puerperium, 2-5 times more likely to occur than pregnancy states，especially in 6 weeks after delivery. PA-VTE is extremely harmful and has become one of the important causes of maternal death in developed countries. The proposal of PA-VTE is intended to emphasize that its prevention, diagnosis and treatment should be based on the pathophysiological characteristics of the special stage of pregnancy. At present, some countries have reached a consensus on the prevention and treatment of PA-VTE, but only a few VTE management guidelines in China mention the prevention and treatment of this kind of disease, and the specific prevention and treatment plan is still unclear. In clinical practice, it is urgent to develop guidelines suitable for the prevention and treatment of patients in China, so as to regulate the clinical practice in China. This article is a systematic review of the pathophysiological characteristics, clinical screening, prevention and treatment of PA-VTE and the current situation of clinical practice in China.
