Vasa previa with bipartite placenta and velamentous cord insertion.

Vasa previa is a rare but potentially life-threatening obstetric condition characterized by fetal vessels traversing the membranes over or near the internal cervical os. Without prenatal diagnosis, it carries a perinatal mortality rate exceeding 50% due to the risk of Benckiser hemorrhage upon membrane rupture. We present the case of a 24-year-old primigravida diagnosed with vasa previa associated with a bipartite placenta and velamentous cord insertion at 32 weeks of gestation. The diagnosis was initially made at the referring hospital in Bordeaux and confirmed at our institution using transvaginal ultrasound with color Doppler imaging. The patient underwent a planned cesarean delivery at 36 weeks and 5 days, resulting in a healthy female neonate weighing 2600g with excellent Apgar scores (9/10/10). This case highlights the critical importance of prenatal diagnosis of vasa previa and the excellent outcomes achievable with timely cesarean delivery before the onset of labor. Transvaginal ultrasound with color Doppler remains the gold standard for detection in high-risk pregnancies.
