“…MRI is an accurate tool with which antenatal diagnosis of vasa previa can be made [29,30]; however, it is expensive and not widely available, and thus, at present, is not a method that can be used in most obstetric practices to diagnose vasa previa.…”

The perinatal mortality rate of vasa previa is high if it is not prenatally diagnosed. In this report, a case of vasa previa diagnosed prenatally is presented. Antepartum hemorrhage at 24 weeks of gestation prompted a close investigation of the uterine cervix, internal os, and placenta. We detected a low-lying bilobed placenta with umbilical cord insertion in the lower uterine segment. Furthermore, one of the connecting vessels of the bilobed placenta passed directly above the internal os. Vasa previa was suspected and confirmed with color Doppler and MRI. The fetus was delivered uneventfully by planned Cesarean section at 38 weeks of gestation. It should be considered that placenta previa (including low-lying placenta), bilobed placenta, and umbilical cord insertion in the lower uterine segment are associated with high risk of vasa previa. Ultrasound screening for cord insertion and placenta around the internal os enables efficient and certain detection of vasa previa.

“…In some cases, fetal heart rate abnormalities such as decelerations, bradycardia and a sinusoidal fetal heart rate pattern may lead to a caesarean delivery and diagnosis of a vasa previa. Magnetic resonance imaging (MRI) has also been used to diagnose vasa previa, but is not in wide usage in obstetrics, and requires expertise that is not readily available 20,21 . The only reliable method of diagnosing vasa previa therefore is ultrasound 2,9,10 .…”
