Prenatal diagnosis of vasa previa through color Doppler and three-dimensional power Doppler ultrasonography. A case report
Vasa previa occurs in pregnancy when one of the membrane vessels extends down to the level of the internal cervical os, ahead of the fetal presenting part and unsupported by the placenta tissue or umbilical cord. The rupture of the vessels might happen spotaneously or artificially and frequently results in fetal exsanguination and demise. Ultrasound prenatal diagnosis is highly important as it allows the identification of patients at risk, thus an elective cesarean can be perfomed before rupture the membranes. We report a case of vasa previa diagnosed through color Doppler mode in the 30th week of gestation, emphasizing the contribution of threedimensional power Doppler to the adequate mapping of aberrant vessels, which greatly contributed to the success of the perinatal result.
