Complications
Conjoined twins are at high risk to being stillborn or dying shortly after birth. In some cases, a healthy twin and a parasitic twin are born. The parasitic twin has no hope for survival and dies and is then surgically separated from its twin. Depending upon how the twins are attached and what is shared among them, complications can arise from surgically separating the live twin from the dead twin. In Ischiopagus cases, the children share a pelvic region along with the gastrointestinal tract and genital region. Most Ischiopagus twins will need reconstruction surgery of the genitals and the GI tract so that the twin will be able to perform normal bodily functions.
For the Ischiopagus twins that both survive from birth, complications and risks also arise. Usually if the both twins survive labor, one twin will be healthy and strong, while the other is malnourished and weak. Thus, surgery would have to be planned in advance to understand the best option and how to keep both children alive during surgery as well as afterwards.
