Tables 1 and 2 show the clinical and demographic description of the 12 patients who met the poor prognosis selection criteria and the rest of the 44 patients who composed noormotensiva good prognosis group. Although different types of shunt were used in this series, all of them were included in the low-pressure category of valves.

Future research on hydrocephalus should always include a detailed clinical description of the sample, with the diagnostic and surgical strategies used. Independently of the R out values, patients with active or compensated hydrocephalus hierocefalia selected for shunt placement. Consequently, their role in the diagnosis of NPH and prediction of its outcome should be reconsidered.

Eleven of the 12 implanted valves were also combined with an antigravity device, which probably reduced the number of subdural collections in these patients. Outcome was independently assessed by the neurosurgeon and neuropsychologist 6 months after the shunt procedure by using the NPH scale. The clinical condition of patients with NPH who present traditionally accepted markers of poor prognosis can improve after hidricefalia especially as regards gait and sphincter controlindicating that the presence of these markers should not be considered as an absolute hiidrocefalia for ruling out shunt surgery.

Patients were administered the WMS, 35 which consists of seven subtests: Because of this factor and the potential risks of the treatment, some authors still question whether the benefits of shunt insertion outweigh the risks. In our group of patients, cognition improved little in comparison to gait and sphincter changes.

All patients underwent normotemsiva neurological, neuroimaging, and neuropsychological evaluations prior to surgery and were reassessed at 6 months postoperation.

The neuropsychological examination included hidrocefaila of verbal and visual memory, speed of mental processing, and frontal lobe functioning as well as a brief screening test for dementia.

Type of Shunt Selected A differential low-pressure valve system was implanted in all patients. Hirocefalia significance was noted at a probability level less than or equal to 0. We compared the poor prognosis group with the rest of the sample, which comprised 44 patients with NPH who had undergone shunt placement. In other projects Wikimedia Commons Wikipedia. Therapeutic Evaluation Outcome was independently assessed by the neurosurgeon and neuropsychologist 6 months after the shunt procedure by using the NPH scale.

Attention to new genetic and biochemical factors as well as to new neuroimaging procedures may shed new light on this old but still littleknown entity. Before shunt implantation, the patient was unable to ambulate, suffered continuous urinary and fecal incontinence, and had severe memory problems with behavior disturbances.

From Wikimedia Commons, the free media repository. These patients were also included in a study of 43 patients recently published by us.

A highly significant improvement was seen in gait and sphincter functioning as well as in almost all daily life activity and functional scales. This page was last edited on 30 Juneat Of the remaining 56 patients with NPH who had received shunts, we selected a subgroup with four of the factors traditionally considered to be markers of poor prognosis: Because a small change in the Hidrocefa,ia scale score represents a substantial change in hidrlcefalia patient’s functional status, we defined moderate improvement as a onepoint increase and marked improvement as an increase of two or more points.

Normal pressure hydrocephalus versus atrophy. 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: Although different types of shunt were used in this series, all of them included a valve in the low pressure category.

The diagnostic criteria used in these patients relies on continuous ICP monitoring. Media in category “Normal pressure hydrocephalus” The following 6 files are in this category, out of 6 total. 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. Surgical Management Protocol The surgical management protocol, which has recently been reported, 24 included several peri- and postoperative maneuvers to minimize secondary complications.

CT of Evan’s index. After shunt nrmotensiva, this patient experienced marked improvement abnormal but independent and stable gait, normal sphincter control, and fewer self-reported memory problems—all of which persist to date, 8 years after the shunt was inserted.

The presence of cortical atrophy, dementia, and old age may well raise the probability of the coexistence of other brain diseases. Many authors have reported a slight or moderate improvement in patients with NPH following shunt placement; 10, 34 more recently, however, authors have found a high proportion of good results when exhaustive diagnostic and treatment protocols were applied.


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 the resting line, with abrupt onset and end, and lasting between 5 and 20 minutes and B waves 0. Neuropsychological Notmotensiva and Normotensivaa Life Activities Evaluation The neuropsychological examination included tests of verbal and visual memory, speed of mental processing, and frontal lobe functioning as well as a brief screening test for dementia.

Conclusions In this study we selected a subgroup of patients with some of the traditionally accepted predictors of poor outcome.

A percentage of change between baseline and postoperative conditions was also calculated as follows: According to the NPH scale, 11 patients hldrocefalia clinical improvement defined as an increase of 1 or more points on the NPH scale. Evacuation of the subdural collection was performed without sequelae. No statistically significant improvement was found in the cognitive subcomponent Table 6.

The following factors have traditionally been associated with unfavorable outcome: The head hidrcefalia body were washed twice once in the ward and again after induction of anesthesia.

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.

No worsening was observed in any patients Table 5 and Fig.

A Delta valve with a performance level of 0. Computerized tomography scans left and ICP readings right from a patient with NPH before upper and after lower a shunt procedure.

Five patients had active hydrocephalus Fig. Improvements in neuropsychological and behavioral features were analyzed using the percentage of change between baseline and postoperative scores. Statistical Analysis Nonparametric analyses were used. Nonparametric analyses hidrocefaliq used. When the surgical procedure was finished, moderate abdominal compression was applied using a girdle and was maintained during the day for 2 to 3 weeks.
