VASA PREVIA: THE CASE FOR ROUTINE SCREENING.

The authors discuss aspects of vasa previa, a medical condition in which fetal vessels traverse the membrane located between cervix and part of the fetus, and routine prenatal ultrasound. Topics discussed include diagnosis of vasa previa, prenatal care, and fetal fibronectin (fFN) testing. They mention that colour flow Doppler sonography should be conducted as an adjunct to rule out vasa previa in patients.
