OBJECTIVE: This study evaluated the correlation between placental lakes and non-reassuring fetal status.

SUBJECTS AND METHODS: We analyzed data from pregnant women who underwent fetal echocardiography at the Fujian Maternity and Child Health Hospital. Women with singleton pregnancies at a gestational age of 20-24 weeks were included. Sociodemographic and clinical data were collected. Pregnant women with (case group) and without (control group) placental lakes were screened, and their placental Doppler ultrasound data and pregnancy outcome were recorded. Univariate and multivariable analyses were done to evaluate the correlation between the volume of placental lakes and the non-reassuring fetal status.

RESULTS: A total of 1,728 pregnant women (156 with placental lakes) were included in this study. There were no significant differences in age of delivery and BMI between the pregnant women with placental lakes and the control group. The non-reassuring fetal status rate in the case group was higher than that in the control population, without statistical significance (5.8% vs. 3.5%, p=0.226). Subgroup analysis showed that a higher volume of placental lakes was positively associated with non-reassuring fetal status risk, with an odds ratio (OR) (95% CI) of 1.90 (1.29-2.66) (p for trend < 0.001). This positive correlation persisted even after adjustment for confounding factors.

CONCLUSIONS: Taken together, our analyses demonstrated a graded increase in the non-reassuring fetal status rate with increased volume of placental lakes. Thus, robust clinical monitoring of placental lakes would help in timely detection of non-reassuring fetal status.
