Objective : Our objective was to investigate a possible clinical usefulness of the measurement of the inferior vena caval diameter (IVCD) during the late second trimester in predicting obstetrical complications. Methods : IVCD was measured in the supine and complete left lateral positions in 281 pregnant women at 24–27 weeks' gestation. Results : In 35 cases who showed the IVCD≤10 percentile in the complete left lateral position, there were six cases with pregnancy‐induced hypertension and seven cases with a compromized fetus (with fetal distress and/or an Apgar score≤7 at 1 min), each incidence being significantly higher compared with cases with IVCD>10 percentile. Conclusion : The measurement of IVCD in the complete left lateral position may provide a valuable tool in predicting pregnancy outcome given its non‐invasiveness and easiness.
