ABSTRACT: The twin reversed arterial perfusion
(TRAP) sequence is an anomaly unique to monochorionic multiple pregnancies. It
is a rare complication. We present a case of acardius anephus, which was
mistaken for a live anomalous singleton fetus. A 21-year-old unbooked
Primigravida was seen in labour ward with a ten hours history of labour pains.
Urgent transabdominal ultrasound revealed a singleton live fetus at 30 weeks
gestation with gross cystic mass lesion at the level of the abdomen and
polyhydramnious.Caesarean section confirms a twin gestation with
monoamniotic monochorionic single placenta. The umbilical cord of the acardiac
twin was short—First twin was a live female baby, weighing 1000 g. TRAP is a
rare event an early referral to feto maternal unit will improve perinatal
outcome.
