Vasa Previa
Diagnosis of Vasa Previa
Ultrasonography Doctors may suspect vasa previa when ultrasonography, routinely done earlier in the pregnancy, detects certain abnormalities in the placenta or when the fetus's heart rate is abnormal. Ultrasonography, usually done with a device inserted into the vagina (called transvaginal ultrasonography), can show the blood vessels crossing over or near the opening of the cervix and thus confirm the diagnosis.
