Abstract
Craniopagus twins are conjoined twins fused at the cranium. This is the rarest anomaly seen in conjoined twins and craniopagus twins account for 2- 6% of conjoined twins. Conjoined twins are also extremely rare, with the anomaly seen in about 10-20 subjects per billion births. A female preponderance has been noted. Craniopagus twins can be classified into complete or partial, depending on whether or not they have shared dural venous sinuses. They can be further classified into angular or total depending on the alignment of the inter-twin longitudinal axis. Surgical separation of these cases can be an elective procedure or an emergency, mandated by the death of one of the twins. Surgical separation of craniopagus twins is a complex exercise needing detailed evaluation and planning. For the successful management of these twins, a multi-disciplinary approach involving neurosurgeons, plastic surgeons, anesthetists, radiologists, pediatric critical care specialists and ancillary staff is mandatory. We present a case of partially successful elective separation of partial angular craniopagus twins performed in 2002.The surviving twin was managed conservatively for a cerebrospinal fluid leak. The patient subsequently developed a pseudomeningocele, necessitating re-exploration, excision of the gliotic tissue, and repair of the dura and the overlying scalp flap. The patient has a skull defect for which cranioplasty has been deferred. The child is neurologically intact. The post-operative evaluation and the detailed periodic neurological assessment till date (with a follow up of 15 years) have been presented in this study.
