Abstract:

Objective To explore risk factors of venous thromboembolism（VTE） in full-term delivery women,so as to construct a rapid assessment form of VTE in full-term postpartum women and to test its predictive effects. Methods A retrospective case-control study was conducted to collect 29 cases of full-term postpartum women with VTE from April 2018 to September 2019 in an observation group,and 58 cases of women with delivery time of a week before or after the deliver time of the observation group were selected in a control group. Chi-square test and Logistic regression were conducted to determine the risk factors of VTE in women after full-term delivery,and a rapid assessment form of VTE in full-term postpartum was constructed to analyze the differentiation of the rapid form and the effects of risk prediction. Results Multivariate logistic regression showed that age,BMI before delivery,gestational diabetes mellitus,family history（thrombosis,diabetes,cardiovascular disease）and pregnancy mode were independent risk factors（P<0.05）. The difference between high risk group and low risk group was statistically significant（P<0.001）. The area under ROC curve was 0.757;the sensitivity was 55.2%;the specificity was 74.1%. Conclusion The age≥35 s,BMI≥30kg/㎡ before delivery,gestational diabetes mellitus,family history of related diseases and assisted reproductive technology are more likely to cause VTE after full-time delivery. The rapid assessment form of VTE in women after full-term delivery has a good differentiation,which can predict the risk of VTE in full-term postpartum women with a certain clinical value for application.
