RESUMO
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 < or = 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.

OBJECTIVE: To present a case of ovarian hyperstimulation syndrome in which antithrombin III activity in plasma was decreased and in ascites was increased. DESIGN: Case report. SETTING: Hospital-based clinic for reproductive medicine. PATIENT(S): A 27-year-old woman who was transferred to our hospital because of ovarian hyperstimulation syndrome. INTERVENTION(S): Induced abortion. MAIN OUTCOME MEASURE(S): Antithrombin III activity in plasma and ascites. RESULT(S): Antithrombin III activity in ascites was slightly lower than that in plasma. CONCLUSION(S): The loss of antithrombin III into ascites probably caused its deficiency in this case.
