A case report of vasa previa incidentally discovered.

Vasa previa is a rare but clinically important obstetrical complication that can be associated with a low-lying placenta or placenta previa. We aim to present one case of vasa previa diagnosed during the placenta examination after the caesarean indicated for triple uterus scar. A 26-year-old female was referred to our hospital at 30 weeks of gestation to provide a scheduled caesarean. Trans-abdominal ultrasound was performed; the placenta was positioned in the posterior side of the fundus. Fetal growth was found to be appropriate for gestational age. A healthy male infant weighing was successfully delivered via cesarean section at 38 weeks of gestation. This operation helped to prevent complications due to acute fetal bleeding. The identification and exclusion of vasa previa using trans-vaginal ultrasound are essential to ensure appropriate and timely treatment.
