Placental examination with dye injections in post-delivery chorionicity assessment in dichorionic triplet pregnancy

The incidence of spontaneous triplet pregnancy is approximately 1 in 7000 deliveries. Due to the fact that every presentation of a triplet and higher order pregnancy is associated with high rate of morbidity and preterm delivery, chorionicity and amnionicity remain significant predictive factors which determine specific management throughout the pregnancy. Ultrasound chorionicity assessment in triplet pregnancies is more complex than in twins, and in many cases it remains unknown. We present a case report of a 24-year-old primipara in a spontaneous dichorionic triplet pregnancy, qualified for a cesarean section at 33 weeks of gestation, with subsequent placental examination with dye injections and post-delivery chorionicity assessment.
