Abstract

Regarding type-3 vasa previa, some branches exit the placental surface and subsequently re-enter at the placental cotyledons. We present a case of type-3 vasa previa diagnosed at 32 weeks of gestation. A 38-year-old pregnant Japanese woman was re-examined using transvaginal color Doppler due to suspected vasa previa on previous routine obstetric examination. Color Doppler clearly showed a small velamentous artery near the internal cervical os. At 37 weeks and 6 days of gestation, a planned cesarean section was performed, resulting in a viable, single female newborn weighing 2,726 g. Placental examination showed peripheral insertion of the umbilical cord with one aberrant vessel.
