Abstract
Numerous complications following the ventriculo-atrial shunt for congenital hydrocephalus have been documented and discussed during the past two decades. Recently a few cases of secondary craniosynostosis have been described in the literature as a rare complication after shunting operation. Authors had a chance to follow up this rare complication subsequent to the ventriculo-atrial shunt for hydrocephalus. Sudden and persisting reduction of intracranial pressure is assumed to be the main contributing factor for producing premature synostosis of cranial sutures which were proved to be once separated each other in hydrocephalic condition.
