ABSTRACT

Conjoined twins of the thoracopagus variety are rare. They are usually female. This case was unusual in that they were male with and one respiratory tract, heart and upper digestive tract (until the jejunum) between them. According to the literature, 60% of conjoined twins are born alive and 35% live only one day. There is disagreement concerning the classification and embryogenesis of this condition and most accept Spencer’s theory which, after a revision of 1800 cases, postulates that the anomaly results from a secondary union of two embryonic discs originally separate. Probable in the present case the fusion must have occurred at an early stage, because of the fusion of structures in the posterior region of the embryonic disc.
