Abstract:
Conjoined twins occurred in one of every 58,000 births. Parapagus dicephalus tribrachius with a
single heart is a scarce variant of conjoined twins. A male parapagus conjoined twins with
tribrachius was born by cesarean section with severe asphyxia, weighing 3170 g from 25 years
old mother with G1P0A0, 35–36 weeks gestation. There is one umbilical cord, and the placenta
consists of 1 amnion, one chorion. The baby has a single heart, a pair of the lung, a single
stomach, duodenum, liver, double columna vertebralis with the single pelvis, one penis,
undescended right, and left testes, one anus, and a pair of inferior extremities. After 28 h of
treatment, the patient’s condition became unstable, deteriorated, and died. This case reminds us
of the importance of antenatal care and ultrasound examination since early pregnancy.
