Abstract:

Objective

To investigate the detection rate and risk factors of abnormal prethrombotic state and its association with pregnancy outcomes in pregnant women with fetal growth restriction.

Methods

A retrospective study was conducted on 182 pregnant women with FGR treated at our hospital from January to December 2024. Data collected included maternal age, pre-pregnancy body mass index (BMI), mode of conception, obstetric history, gestational age at first FGR diagnosis, gestational age at prethrombotic state testing, pregnancy complications and comorbidities, TORCH screening results, prenatal screening or diagnostic findings, medication during pregnancy, and pregnancy outcomes. Laboratory tests included antiphospholipid antibody profiles, antinuclear antibodies, protein C/S, antithrombin Ⅲ (AT-Ⅲ), and homocysteine levels. Patients were divided into an abnormal group (n=99) and a normal group (n=83) based on test results. Clinical characteristics and pregnancy outcomes were compared between the two groups.

Results

Prethrombotic state abnormalities were detected in 54.3% of FGR pregnant women. Compared with the normal group, the abnormal group had significantly higher levels of anticardiolipin antibody IgM, anti-β2-glycoprotein I antibody IgM, lupus anticoagulant screening/confirmatory ratio, anti-phosphatidylserine/prothrombin antibody IgM, and antinuclear antibodies, along with significantly lower levels of AT-Ⅲ activity and protein S, with all differences being statistically significant (all P<0.05). Multivariate logistic regression analysis identified maternal age (OR=1.10, 95%CI: 1.01-1.20) and high pre-pregnancy BMI (OR=1.10, 95%CI: 1.00-1.22) as independent risk factors for prethrombotic state abnormalities.

Conclusions

Advanced maternal age and high pre-pregnancy BMI are independent risk factors for prethrombotic state abnormalities in pregnant women with FGR, with a high detection rate. Screening for prethrombotic state is recommended in FGR patients with these risk factors to improve pregnancy outcomes.
