Hydrocephalus is the most recurrent neurosurgical problem come across in the pediatric age group in which cerebrospinal fluid is built excessively in the brain and causes pressure on brain. Cerebrospinal Fluid (CSF) shunting procedures constitute roughly half of utmost pediatric neurosurgical practices; with roughly half of these procedures performed for modification of a being shunt. Easily, despite recent advances in shunt design, they continue to present a specialized challenge for the neurosurgeon treating children with Hydrocephalus

Babies and children who present with ventriculomegaly and clinical substantiation of elevated intracranial pressure easily bear a CSF diversionary procedure. Whereas conventional CSF shunting procedures have long been the main treatment option in these children, dissatisfaction with their long- term outgrowth and significant failure rates has redounded in a rejuvenescence of interest in the foremost form hydrocephalus treatment ventriculostomy. Case groups flaunting roughly high success rates following third ventriculostomy are still being defined, still, and presumably represent less number of cases with hydrocephalus. CSF shunting procedures are likely to remain the treatment of choice for utmost children with characteristic ventriculomegaly.

The decision to treat ventriculomegaly becomes more delicate in the case whose symptoms are minimum, absent, or delicate to assess because of the case's age. Radiographic progression of ventriculomegaly over time, indeed if asymptomatic, is generally considered an suggestion to treat, unless it's secondary to cortical atrophy associated with anoxia, syndromic deformations, or degenerative /metabolic complaint. Lower agreement exists, still, about the treatment of asymptomatic stable ventricular enlargement. The inconsistent use of the terms arrested and compensated hydrocephalus adds to this contestation. Cases with stable ventricular blowup performing from age related CSF immersion abnormalities or venous occlusive complaint considered for treatment unless radiographic or clinical progression is easily proved. Children with stable clinical and radiographic findings over the age of 5 times can be covered nearly for substantiation of subtle abnormalities in intellectual development. It's important to weigh the given long- term pitfalls of shunt complications against the largely unknown impact of asymptomatic hydrocephalus in this group of cases. Youngish children particularly those under the age of 3 times, cannot be estimated by standard measures of intellectual development. Numerous

authors recommend treatment of asymptomatic cases with moderate to severe ventriculomegaly in this age group to cover against the impact of ventriculomegaly on unborn intellectual performance. Unfortunately, imaging studies and invasive testing, including infusion tests, radionuclide studies, Doppler webbing, intracranial pressure monitoring, and glamorous resonance (MR) spectroscopy, to date have been unfit to prognosticate reliably which of these children may be at threat for intellectual decline.

The opinion of hydrocephalus is grounded on clinical and radiological features. Babies most generally present with symptoms of perversity, delayed development, puking, and headache and on examination have adding head circumference and a bulging fontanel. MR imaging has the stylish individual mileage in terms of establishing the deconstruction and likely pathology of implicit obstructive lesions. Computed Tomography (CT) is generally sufficient for follow-up of preliminarily diagnosed cases with being shunt systems and primary or critical evaluations of undiagnosed cases. Ultrasound is more practical in critically ill, unseasonable babies with intraventricular hemorrhage or in babies with myelomeningocele the etiology of which isn't in mistrustfulness. Moderate to severe ventriculomegaly generally can be imaged fluently using any of these ways. In cases with milder ventricular blowup, substantiation of transependymal inflow of CSF generally suggests that the process is more acute. Other signs of progressive hydrocephalus similar as blow up of the temporal cornucopias, dilatation of the third ventricle, and effacement of the sulci are less specific. However, careful observation with periodical images, rather than subjugating the case to the known pitfalls of shunt failure, If mistrustfulness exists.

Important considerations must be taken into account, still, when assessing the individual patient age, weight, skin consistence, head size, size of the ventricles, pathogenesis of hydrocephalus, acuteness of the illness, presence of internal lines or gastrostomy, tracheotomy openings, status of the distal drainage point, and plans for farther surgery. For illustration, a unseasonable child with thin skin stretched further by a fleetly expanded head cannot accommodate adult-sized outfit without the threat of skin corrosion. The presence of intraventricular hemorrhage in this case group also may increase the threat of early inhibition following implantation of a stopcock with a narrow inflow- limiting perforation. Again, in cases with large ventricles and large craniums with fused sutures, placing an inflow- limiting or siphon- reducing device may drop the threat of subdural hemorrhage. Ventricular configuration and asymmetry also may mandate the choice of insertion point.
