Abstract: Thrombelastography(TEG) is an image which can reflect the ability of coagulation, blood clotting and fibrinolysis dynamically. TEG can reflect the coagulation state in pregnant women veritably and comprehensively. TEG has important value for predicting the high-risk pregnancy such as recurrent spontaneous abortion, hypertensive disorders in pregnancy. Some peripartum complications such as amniotic fluid embolism, postpartum hemorrhage and venous thrombus embolism can also be evaluated by TEG.

Key words: Thrombelastography(TEG), Hypercoagulation, High-risk pregnancy
