Vasa previa with velamentous cord insertion: a case report

Abstract

Vasa previa is a rare and infrequent prenatal finding of hemorrhage in the second
half of pregnancy, in which umbilical vessels devoid of Wharton's jelly interpose
between the fetal presentation and the internal cervical os. When undetected and
rupture of the vessels occurs, it is associated with a high perinatal mortality rate.
Three types are described; the case presented is type 1 vasa previa secondary to
velamentous insertion of the cord. It was diagnosed prenatally by transvaginal
ultrasound associated with color Doppler. A cesarean section was performed with
favorable maternal and perinatal evolution
