Abstract： Objective： To observe the clinical effect of point massage combined with low molecular weight heparin in preventing deep venous thrombosis after cesarean section. Methods：A total of 92 cases of puerpera undergoing cesarean section were divided into the observation group and the control group according to the random number table method， 46 cases in each group. The control group was treated with low molecular weight heparin， and the observation group was additionally treated with point massage based on the treatment of the control group. The clinical symptom scores，the blood flow velocity and blood vessel diameter of lower extremity， the coagulation indexes and the incidence of postoperative complications in the two groups were compared. Results：After treatment，the scores of tenderness，swelling，soreness and pain in lower extremity in the observation group were lower than those in the control group，differences being significant (P＜0.05). After treatment，the blood flow velocity in the observation group was faster than that in the control group，and the blood vessel diameter was smaller，differences being significant(P＜0.05). After treatment，the levels of thrombin time(TT)， prothrombin time(PT) and activated partial thromboplastin time(APTT) in the observation group were lower than those in the control group， differences being significant(P＜0.05). The incidence of postoperative complications was 2.17% in the observation group， lower than that of 19.57% in the control group， the difference being significant(P＜0.05). Conclusion： Point massage combined with low molecular weight heparin in preventing deep venous thrombosis after cesarean section can improve coagulation indexes and blood flow velocity of lower extremity， and reduce the incidence of postoperative complications.
