At this point, the fetal Doppler showed the following results: UA PI, 1.39; MCA PI, 1.57; UVFV, 72 mL/kg/min; DV PI, 0.58; CTAR, 17.1%; inferior vena cava PLI, 0.4; and TEI index (left/right ventricle), 0.474/0.581.
In Case 1, decreased intra-amniotic pressure decreased UA PI and increased UVFV, and, in Case 2, decreased fetal intraperitoneal pressure decreased UA PI.
