Research progress on risk factors for deep venous thrombosis in pregnant women and risk assessment

妊娠状态和分娩相关事件均可能增加孕产妇DVT风险，孕期及产后静脉血栓栓塞症的危害性已经超过产后出血，成为发达国家孕产妇发病和死亡的首要原因，DVT的临床特点及治疗的特殊性决定了早期评估和预防工作的重要性。本文对国内外孕产妇DVT发生的原因、特殊危险因素及评估研究现状进行综述，以期为临床孕产妇DVT风险评估及预防提供参考。

Pregnancy and childbirth-related events may increase the risk of maternal deep venous thrombosis （DVT）. Pregnancy and postpartum venous thromboembolism have been more harmful than postpartum hemorrhage and become the leading cause of maternal morbidity and mortality in developed countries. The characteristics and special treatment determine the importance of early assessment and prevention. This paper tries to summarize the causes and special risk factors of DVT in pregnant women at home and abroad as well as the research progress on risk assessment, in order to provide reference for clinical risk assessment and prevention of maternal DVT.
