In this study, the valve used was a fixed pressure valve. They differ in the cerebrospinal fluid CSF flow mechanism.

In fixed pressure valves, the CSF flows through the shunt when the intracranial pressure reaches a fixed threshold. In programmable valves, this threshold may be adjusted according to the patient's symptoms. Thus, the most adequate pressure can be achieved for each patient.

In flow-regulated valves, the CSF flow is continuous, regardless of pressure. These valves may differ in price, given that programmable valves and flow-regulated valves involve more advanced technology and are more expensive. Qualitative evaluation through epidural monitoring reveals Lundberg B waves with spikes of up to 50 mmHg, occurring mainly at night.

These waves reflect the dynamics of the production, circulation and absorption of CSF, indicating that cerebral compliance is abnormal.

A series of 90 patients was reported with satisfactory clinical results. Despite fixed pressure valves being used with good results, there are complications caused by overdrainage in a significantly higher percentage.

Some studies suggest that the advantage of reprogramming programmable valves is not translated into a reduction in surgical revisions and, therefore, fixed pressure valves could be used. Higher resistance to outflow was found in patients with obliterated cortical sulci and obliterated Sylvian cisterns in the CT scan.

No statistically significant correlation was found when plotting the percentage of beta waves against pressure volume index PVI , compliance or Rout. Additional studies taking into consideration these differences are necessary before defining the sensitivity, specificity and predictive value of ICP monitoring and CSF studies in selecting appropriate candidates for shunting.

Because of this, patients do not exhibit the classic signs that accompany increased intracranial pressure such as headache, nausea, vomiting, or altered consciousness, although some studies have shown pressure elevations to occur intermittently.

The exact pathogenesis is unknown, but consensus on some mechanisms include: An imbalance exists between production and resorption of CSF.

The resistance to CSF outflow is often elevated. The syndrome is often divided into two groups, primary also called idiopathic and secondary, based on cause.

Initial Experience with the Hakim Valve for Ventriculovenous Shunt

The underlying etiology of primary NPH has not yet been identified. Primary NPH affects adults age 40 years or older, most commonly affecting the elderly.

Secondary NPH can affect persons of any age and occurs due to conditions such as subarachnoid hemorrhage , meningitis , brain surgery, brain radiation, or traumatic brain injury. Diagnosis[ edit ] Evan's index is the ratio of maximum width of the frontal horns to the maximum width of the inner table of the cranium.Chin Med J Engl.

FA, however, increases in the internal capsule, especially in its anterior limb, and decreases in the corpus callosum, especially at the level of the genu. Figure 5. It is also noteworthy to emphasize the role of brain MRI in this setting where transependymal CSF resorption might be mistaken for age-related white matter changes or leukoaraiosis on brain CT imaging.
