Prenatal diagnosis of vasa previa

Abstract

Vasa previa is a rare condition in which unsupported by the placenta, umbilical cord blood vessels runs within the placental membranes between internal os of the cervix and presenting part of the fetus. We report an antenatal diagnostic procedure and management of a patient with low-lying placenta and velamentous cord insertion near to the internal os with two large fetal blood vessels coursing between the internal cervical os and fetal presenting part. An elective cesarean section was performed at 36 weeks gestation.
