Methods Twenty MCDA placentae (55% anterior and 45% posterior) were examined between 12-26 weeks’ gestation. The patients’ mean BMI was 26.96 (ranging between 20.08 e 44.00). A Canon Aplio US machine was used to apply different colour Doppler modalities to identify the vascular equator and placental vessels between the two cord insertions (see image). Pulse wave Doppler characterised the blood flow within the vessels identified. Ultrasound imaging was recorded for offline analysis and placental “maps” were created.
