Placenta Previa Diagnosis & Tests
The uterus is usually soft and relaxed. The infant position is oblique ( // ) or transverse ( == ) in about 15% of cases. Fetal distress is not usually present unless a cord accident occurs, or vaginal blood loss has been heavy enough to induce maternal shock or placenta abruptio.
An abdominal ultrasound performed during the second trimester indicates low positioning of the placenta. Transvaginal or transperineal ultrasound can help physicians determine the position of a low-lying placenta.
