A rare case of dicephalous dibrachius dipus conjoined twins:case report

Conjoined twin is a rare complication seen in 1% of monochorionic monoamniotic twins and associated with severe morbidity and mortality. We are reporting a case of 30 years old second gravida referred to our tertiary care center at 35 weeks of gestation with ultra-sonographic diagnosis of dicephalus conjoined twin and further confirmed after caesarean delivery.

One of the most interesting congenital malformations is a conjoined twin. Conjoined twins are a rare occurrence in obstetric practice. More commonly known as Siamese twins, this phenomenon is shrouded in mystery and considered a curiosity by general public. Current technology is providing a basis for earlier diagnosis and a better prognosis. Frequently, the twins are born dead, but there are a few cases in which the twins survive. We present a case of thoraco-omphalophagus with omphalocele in 35 years old woman at 25weeks 5 days gestation by 3-D ultrasonography and MRI.

A Case of Thoracopagus / 대한산부인과학회잡지

Thoracopagus is very rare congenital anomaly with an incidence estimated at 1 in 50,000 deliveries or 1 in 600 twin deliveries. If twining is initiated after the embryonic disc and the rudimentary amnionic sac have been formed, and if division of the embryonic disc is incomplete, conjoined twins result. We experienced a case of thoracopagus in 28 years old woman. We present this case with a brief review of literatures.

Conjoined twins occur when there is imcomplete fission of the inner cell mass later at approximately 13 to 15 days after fertilization. The earlist case in the literat.ure appears to be that of the Biddenden Maids who were born in England in 1100. since then over two hundred cases of successful separation were reported on literature. And also successful separation cases were reported by Seung et al.(1991) in Korea. Conjoined twins occur between one in 50,000 to 100,000 births but real incidence is one in 200,000 because two thirds are stillbirth or died immediately after birth. The conjoined twins are not associated with maternal age, race or family history and 70 % of them are females. We experienced a case of conjoined twins with omphalopagus and performed surgical separation. A brief review of related literatures was done.
