Abstract
Joined in utero, the conjoined twins are known as “Siamese twins.” There are different theories related to aberrant embryogenesis proposing why conjoining occurs. One such theory suggests that a single fertilized egg may not split fully during the process of formation of identical twins, and the zygotic division occurs 2 weeks after the development of the embryonic disc, resulting in the formation of conjoined twins (fission theory). The other theory suggests that two fertilized eggs fuse in the early part of the development process (fusion theory); subsequent splitting of primitive nodes and streak partially may lead to this rare phenomenon. Conjoined twins occur in not more than 1:50,000 to 1:200,000 births. Craniopagus twins (CPTs) are joined at the head, and are very rare forms of conjoined twins. The surgical separation of the CPTs is a complex procedure, and includes multi-staged separation of shared vasculature, interdigitating brain parenchyma, and reconstructive plastic surgery. A successful separation surgery requires multiple episodes of anesthesia along with a multi-disciplinary approach for the overall perioperative management.
