You inform her that the placenta is low lying. When will her follow up scan be scheduled. A. Transabdominal scan( TAS ) 34 weeks B. Transabdominal scan(TAS) and Transvaginal scan ( TVS) at 28 weeks C. Transabdominal scan( TAS) and Transvaginal scan( TVS) at 32 weeks . D. Transabdominal scan( TAS ) at 24 to 26 weeks If the placenta is thought to be low lying (less than 20 mm from the internal os) or praevia (covering the os) at the routine fetal anomaly scan, a follow-up ultrasound examination including a TVS is recommended at 32 weeks of gestation to diagnose persistent low-lying placenta and/or placenta praevia. Use of TVS- to accurately see the placental edge. Also, cervical length is a predictor of antepartum bleeding and emergency preterm caesarean section in placenta praevia.
