Résumé
Today,the incidence and mortality of perinatal thromboembolic diseases show a significant upward trend,which is mainly caused by venous thrombosis after cesarean section.Cesarean section has been identified as a high-risk factor for venous thromboembolism,which is not only related to surgical factors,but also to pathological obstetric factors in most cesarean sections.It is generally believed that the risk of bleeding after anticoagulant therapy after cesarean section is greater,so most postoperative anticoagulant therapy is not performed.However,with the increase of high-risk maternity,in order to minimize the adverse outcome,we should evaluate the risk of bleeding and thrombosis after cesarean section and the reasonable preventive anticoagulant therapy for high-risk women.By summarizing the related literature,this paper discusses how to assess the risk of thrombosis after cesarean section and effectively prevent thromboembolic events in order to determine the best time to perform anticoagulation prevention intervention.
