Abstract In a retrospective study, 39 patients received a low pressure (20 to 50 mm H2O) shunt and 33 received a medium pressure (55 to 85 mm H2O) shunt for the treatment of normal pressure hydrocephalus (NPH). Pre- and postoperative computed tomographic scans were obtained in 32 patients, permitting us to determine the influence of shunt pressure on ventricular size. A reduction in 3rd ventricle width was found to correlate with clinical improvement and was observed more frequently after the placement of a low pressure shunt than after the placement of a medium pressure shunt. When results were evaluated in patients who did not have advanced NPH or develop postoperative complications, gait was markedly improved in 60% of those receiving a low pressure shunt as opposed to 23% of those receiving a medium pressure shunt (P < 0.05).

To assess the value of the information derived from pumping the shunt valve in hydrocephalic patients with cerebrospinal fluid shunts, the findings on examination of 200 consecutive patients were recorded prospectively. The status of each shunt was determined on the basis of all available clinical data, and the results of the shunt pumping test were compared to the final status of each shunt for various subsets of the study group. In the most clinically pertinent subsets, the sensitivity of the shunt pumping test in the detection of shunt obstruction was 18% to 20%, and the predictive value of a negative shunt pumping test, indicating shunt patency, was only 65% to 81%. For the hydrocephalic patient with symptoms of shunt malfunction, definitive imaging studies must not be deferred because of reassuring findings on examination of the shunt valve.

Abstract The Infectious Diseases Society of America (IDSA) Standards and Practice Guidelines Committee collaborated with partner organizations to convene a panel of 10 experts on healthcare-associated ventriculitis and meningitis. The panel represented pediatric and adult specialists in the field of infectious diseases and represented other organizations whose members care for patients with healthcare-associated ventriculitis and meningitis (American Academy of Neurology, American Association of Neurological Surgeons, and Neurocritical Care Society). The panel reviewed articles based on literature reviews, review articles and book chapters, evaluated the evidence and drafted recommendations. Questions were reviewed and approved by panel members. Subcategories were included for some questions based on specific populations of patients who may develop healthcare-associated ventriculitis and meningitis after the following procedures or situations: cerebrospinal fluid shunts, cerebrospinal fluid drains, implantation of intrathecal infusion pumps, implantation of deep brain stimulation hardware, and general neurosurgery and head trauma. Recommendations were followed by the strength of the recommendation and the quality of the evidence supporting the recommendation. Many recommendations, however, were based on expert opinion because rigorous clinical data are not available. These guidelines represent a practical and useful approach to assist practicing clinicians in the management of these challenging infections. Keywords. ventriculitis; meningitis; cerebrospinal fluid shunts; cerebrospinal fluid drains; central nervous system infections.
