The surgical management protocol, which has recently been reported, 24 included several peri- and postoperative maneuvers to minimize secondary complications. Subacute subdural hematoma was diagnosed in a patient before discharge from the hospital.

Figure 1 summarizes the selection criteria of patients included in the present study.

The dura mater was opened by coagulation and as far as possible the size of the hole was limited to the diameter of the ventricular catheter. To achieve this goal, we describe the clinical and neuropsychological outcome 6 months after shunt surgery in a pilot study of a subgroup of patients with NPH who simultaneously presented the following four factors traditionally considered to be markers of poor prognosis in addition to old age: Several other authors hidrocwfalia the view that continuous ICP monitoring is the most useful diagnostic test in evaluating NPH.

If discrepancies were found between the evaluations of the neurosurgeon and the neuropsychologist, the patient was reevaluated and the final score was agreed on by consensus. We found that the factors clearly related to better neuropsychological and functional recovery after shunt hudrocefalia included the presence of a complete clinical triad, obliterated or normal cortical sulci size, and hidrodefalia lucencies.

One additional patient had an asymptomatic subdural collection self-limiting hygroma during the months after shunt placement. The surgical field was then painted with Betadine solution and covered with Betadine-soaked gauze strips for at least 3 minutes.

Although different types of shunt were used in this series, all of them were included in the low-pressure category of valves. Although this procedure restricted us to only 12 patients, the results were highly demonstrative.

We registered mean ICP and the presence and percentage of the total recording time of A waves ICP elevations at least 20 mm Hg above hidrocefala resting line, with abrupt onset and end, normotensiga lasting between 5 and 20 minutes and B waves 0. Retrieved from ” https: Statistical Analysis Nonparametric analyses were used. After shunt placement, this patient experienced marked improvement abnormal but independent and nomrotensiva gait, normal sphincter control, and fewer self-reported memory problems—all of which persist to date, 8 years after the shunt was inserted.


Authors of recent reports in the literature stress the fact that NPH can be highly heterogeneous. The presence of cortical atrophy, dementia, and old age may well raise the probability of the coexistence of other brain diseases.

All patients had some level of cognitive impairment Table 4. The following factors have traditionally been associated with unfavorable outcome: Statistical significance was noted at a probability level less than or equal to 0.

To our knowledge, no study has been focused on the outcome in patients with NPH who show accepted markers of poor prognosis prior to normotenaiva.

Our results normtoensiva show that a good outcome can be obtained and that hidgocefalia surgical complications can be avoided even in this subgroup of patients many of whom would not have been given shunts at other centers.

A low-pressure diaphragm valve American Heyer-Schulte Corp. In the subgroup of patients with a differential-pressure valve and no antisiphon or gravity-compensating accessory, the beds were kept flat for at least 7 to 9 days, after which ambulation was begun. Accordingly, each patient received one of the following classifications: Per idrocefalo normoteso s’intende un tipo di idrocefalo comunicante, in cui l’aumento della pressione intracranicadovuto all’accumularsi del liquido cefalorachidianodiventa stabile, e hidocefalia formazione di liquor si equilibra con l’assorbimento; la pressione intracranica gradualmente diminuisce ma mantiene ancora una livello lievemente elevato.

Six months after shunt placement, only one patient remained totally dependent SLS Grade 4seven patients required supervision SLS Grades 2 and 3and four patients were independent for daily life activities SLS Grades 0 and 1; Table 4.

Outcome was independently assessed by the neurosurgeon and neuropsychologist 6 months after the shunt procedure by using the NPH scale. We selected a subgroup of patients who demonstrated four of the most commonly accepted predictors of poor outcome following shunt surgery.

Comunque il soggetto hhidrocefalia la triade classica: Discussion We selected a subgroup of patients who demonstrated four of the most hidrocefxlia accepted predictors of poor outcome following shunt surgery.

Also administered were the TMT, Parts A and B, 28 to evaluate motor speed, visual scanning, attention, and mental flexibility; a word fluency task consisting of naming as many animals as possible during 1 minute; and the MMSE, 8 which provides a global measure of the severity of cognitive impairment.

Conclusions In this study we selected a subgroup of patients with some of the traditionally accepted predictors of poor outcome. Computerized tomography scans left and ICP readings right from a patient with NPH before upper and after lower a shunt procedure.


Early or late postsurgical complications were found in two of the 12 patients in the poor prognosis group. The percentage of B waves that patients with NPH can demonstrate is highly variable; in the present series, we found wide variation in the percentage of B waves in patients who improved after shunt procedures.

Excluding these patients from surgery means that progressive deterioration is inevitable and will likely have an adverse effect on the quality of life of many patients and their families. We believe these results to be related to the diagnostic and treatment protocols used in this study.

Neuropsychological tests and quality-of-life scales were administered to the patients while they were in the hospital for presurgical studies, and again 6 months later. Subcategories This category has the following 2 subcategories, out of 2 total. No statistically significant improvement was found in the cognitive subcomponent Table 6. Views View Edit History.

A causa di questo equilibrio il paziente non mostra i sintomi classici dell’ipertensione endocranica quali cefaleanausea, vomito o incoscienza. A percentage of change between normtoensiva and postoperative conditions was also calculated as follows: Because of this factor and the potential risks normotnesiva the treatment, some authors still question whether the benefits of shunt insertion outweigh the risks.

Surgical Management Protocol The surgical management protocol, which has recently been reported, 24 included several peri- and postoperative maneuvers to minimize secondary complications. Many investigators have tried to elucidate which factors are associated with a favorable outcome in this patient population; however, an effective means of predicting shunt responsiveness remains elusive.

Evacuation of the subdural collection was performed without sequelae. Sixty-four consecutive patients with suspected NPH, comprehensively described in Poca, et al. The disease affects three main areas—gait, sphincter control, and cognitive functioning—which were evaluated according to the NPH scale Table 3.
