Placental vessels along the chorionic plate were recorded together with the direction of blood flow and their location in relation to the cord insertions and to superficial arterio\u2013arterial anastomoses. Suggestive AVAs were mapped topographically and results were compared with the findings of formal postnatal placental injection studies.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>An AVA was identified in each of the three cases. Injection studies showed multiple AVAs. Each antenatally identified AVA was confirmed at placental injection study. Their placental location correlated to other landmarks as predicted by ultrasound.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>This preliminary report demonstrates that AVAs can be identified using color Doppler ultrasound. This may facilitate planning for highly selective ablation of AVAs, and shorter procedure times. Formal studies are now indicated to determine the accuracy of this technique.
