AbstractConjoined twins have interested people throughout history. In the earliest times they were known as gods, or feared as bad omens and exiled, abandoned or killed. In later days they were viewed as curiosities, and became circus or sideshow attractions. Now days, because of sophisticated separation techniques conjoined twins are no longer looked as freaks but individuals. Approximately 75% of conjoined twins are female, and 70% are fused at the thorax (Thoracopagus) or abdomen (Omphalopagus). The union can be in the frontal, transverse, or sagittal plane. In broad terms, conjoined twins may be regarded as a doubling anomaly. The later the incomplete embryologic separation occurs, the higher the likelihood of a complicated fusion.
