Prenatal Diagnosis of Conjoined Twins (Thoracoomphalopagus) in the First Trimester Pregnancy
We present a case of a 27 year-old primigravida who visited antenatal clinic for the first screening echography at gestational age of 11.5 weeks. Conjoined twins (thoracoomphalopagus) were detected. Additional findings were: omphalocele, single heart, and single umbilical artery in both embryos. Pregnancy was terminated. Advances in prenatal diagnosis allow detailed, accurate evaluation in case of conjoined twins. Careful prenatal studies may uncover cases in which emergent separation at birth is lifesaving.
