Antenatal diagnosis and prognosis of conjoined twins--a case report

In this report, two conjoined twin cases that were diagnosed at the 19th and 25th week of gestational age are reported. In the first case the pregnancy was terminated because of the very poor prognosis. In the second case the decision was made to continue the pregnancy after counseling explaining the possibility of a separation procedure with good prognosis being carried out after birth. The babies were delivered at 38 weeks of gestation and the separation procedure was carried out at ten months of age without any complications. In selected cases, there is no need to abort, because of the possibility of a separation procedure after birth with good prognosis. Color Doppler ultrasound examination in an early stage of pregnancy in cases of conjoined twin can make it possible to decide which cases are candidates for a separation procedure after birth.
