Introduction:
The aim of this paper was to make a preliminary analysis of the risk factors related to venous thromboembolism (VTE) in pregnant women by Meta-analysis.
Evidence Acquisition:
Three databases including PubMed, Web of Science, and The National Library of Medicine (NLM) were systematically searched from their establishment to January 1, 2023, and the obtained data were statistically analyzed using RevMan5.3 software.
Evidence Synthesis:
A total of 10 studies were included, involving 22 risk factors, of which 16 were included for further analysis. Meta analysis showed that cesarean section (OR=2.05, 95%CI: 1.71, 2.47, P=0.007), gestational diabetes (OR=1.17, 95%CI: 1.09, 1.27, P<0.001), eclampsia or preeclampsia (OR=1.88, 95%CI: 1.42, 2.49, P< 0.001), obesity (OR=1.19, 95%CI: 1.04, 1.86, P=0.028), twin or multiple pregnancy (OR=2.34, 95%CI: 1.46, 3.76, P<0.001), chronic heart disease (OR=3.59, 95%CI: 3.28, 3.92, P<0.001), and blood transfusion history (OR=3.20, 95%CI: 2.78, 3.68, P<0.001) were risk factors for VTE in pregnant women.
Conclusions:
Existing evidence suggests that cesarean section, gestational diabetes, eclampsia or preeclampsia, obesity (body mass index ≥30 kg/m2), twin or multiple pregnancy, chronic heart disease, and blood transfusion history may be risk factors for VTE in pregnant women. In clinical practice, the evaluation and management of VTE should be strengthened, and a model for clinical prediction of VTE can be established to provide a reference for the prevention of VTE.
