Introduction:
We aimed to evaluate the risk factors for the development of deep vein thrombosis (DVT) within one month after delivery in pregnant women of advanced maternal age undergoing cesarean section and explore the predictive value of fasting coagulation indicators in relation to the development of DVT.
Methods:
A total of 176 eligible postpartum women were included in this study. Sixty-seven cases developed DVT within one month after delivery (DVT group), while 109 cases did not experience DVT (NDVT group). Within 24 hours after cesarean section, fasting coagulation indicators are measured. Coagulation system analysis was performed using the STA-R Evolution fully automated coagulation analyzer.
Results:
The women who developed DVT were found to be older, had a higher proportion of women with previous childbirth experiences, and had a higher proportion of women with comorbidities. Our results revealed significant differences in the levels of activated partial thromboplastin time and prothrombin time between the NDVT group and the DVT group. In contrast, the DVT group displayed significantly higher levels of D-dimer, plasma fibrinogen and platelet count when compared to the NDVT group. The AUC for the combined test model was substantially higher compared to individual parameters.
Discussion:
Multiple parameters of the postoperative coagulation state in the combined test model provided a more accurate prediction of DVT occurrence in elderly pregnant women after cesarean section.
