Abstract
Foramen ovale (FO) flow may be altered in IUGR. .is study was designed to test this hypothesis. Methods. Forty pregnant women (24–38 weeks) were divided into 3 groups: group I (IUGR), group II (adequate growth and maternal hypertension), and group III (normal controls). Impedance across the FO was assessed by the FO pulsatility index (FOPI): (systolic velocity − presystolic velocity)/mean velocity. Statistical analysis utilized ANOVA, Tukey test, and ROC curves. Results. Mean FOPI in IUGR fetus ...
Foramen ovale (FO) flow may be altered in IUGR. .is study was designed to test this hypothesis. Methods. Forty pregnant women (24–38 weeks) were divided into 3 groups: group I (IUGR), group II (adequate growth and maternal hypertension), and group III (normal controls). Impedance across the FO was assessed by the FO pulsatility index (FOPI): (systolic velocity − presystolic velocity)/mean velocity. Statistical analysis utilized ANOVA, Tukey test, and ROC curves. Results. Mean FOPI in IUGR fetuses (n=15) was 3.70 ± 0.99 (3.15–4.26); in the group II (n=12), it was 2.84 ± 0.69 (2.40–3.28), and in the group III (n=13), it was 2.77 ± 0.44 (2.50–3.04) (p=0.004). FOPI and UtA RI were correlated (r= 0.375, p= 0.017), as well as FOPI and UA RI (r= 0.356, p= 0.024) and, inversely, FOPI and MCA RI (r= −0.359, p= 0.023). Conclusions. .e FO flow pulsatility index is increased in fetuses with IUGR, probably as a result of impaired left ventricular diastolic function ...
