Abstract Infantile hydrocephalus is one of the variable and complex diseases in neurological surgery, hydrocephalus defined as an active distension of the ventricular system resulting from inadequate passage of cerebrospinal fluid from its point of production within the cerebral ventricles to its point of absorption into the systemic circulation. Hydrocephalus in infants which either can be congenital without obvious extrinsic cause or secondary to hemorrhage, infection or neoplasm needs intervention and treatment by one way or another. Endoscopic third ventriculostomy (ETV) is a procedure in which a CSF diversion is created through a ventriculocisternostomy directly into the subarachnoid space, besides it reduces the trans mantle pulsatile stress by increasing compliance of the ventricular wall, this procedure has been debatable in infants due to high discrepancy in failure rates among different studies. Recently, the combination of Etv with Choroid plexus cauterization (CPC) in infants has been widely debatable and promising with favorable results. With the rationale being that an imbalance in CSF absorption capacity may be one of the reasons behind ETV failure. Cauterization of the choroid plexus would, in theory, decrease CSF production, compensating for the presumably hindered absorption capacity of CSF in infants and augment effect of ETV by reducing the amplitude of intraventricular pulsations, depending on hydrodynamic theory of hydrocephalus, depending on pulsatite flow theory of CSF circulation. |
