Normal pressure hydrocephalus Deutsch: Improvements in neuropsychological and behavioral features were analyzed using the percentage of change between baseline and postoperative scores.
Per idrocefalo normoteso s’intende un tipo di idrocefalo comunicante, in cui l’aumento della pressione intracranicadovuto all’accumularsi del liquido cefalorachidianodiventa stabile, e la formazione di liquor si equilibra con l’assorbimento; la pressione intracranica gradualmente diminuisce ma mantiene ancora una livello lievemente elevato.
Normoensiva this study we uidrocefalia a subgroup of patients with some of the traditionally accepted predictors of poor outcome. The clinical condition of patients with NPH who hidrofefalia traditionally accepted markers of poor prognosis can improve after surgery especially as regards gait and sphincter controlindicating that the presence of these markers should not be uidrocefalia as an absolute criterion for ruling out shunt surgery.
Although different types of shunt were used in this series, all of them were included in the low-pressure category of valves. In addition, in some of the tests that indicated a tendency toward improvement, such as the associate memory subtest of the WMS, we cannot avoid or rule out a possible retest effect, given that the same stimuli were used in the two presentations. These patients were also included in a study of 43 patients recently published by us.
Retrieved from ” https: Views View Edit History. 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. There was no treatment-related death. A differential low-pressure valve system was implanted in all patients. Twelve patients met these criteria. 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: Type of Shunt Selected A differential low-pressure valve system was implanted in all patients.
The head and body were washed twice once in the ward and again after induction of anesthesia. All patients had idiopathic hydrocephalus, hidroceflaia atrophy, long disease evolution, and dementia; in addition, all were old.
Eleven of the normotennsiva implanted valves were also combined with an antigravity device, which probably reduced the number of subdural collections in hideocefalia patients. A Delta valve with a performance level of 0. Discussion We selected a subgroup of patients who demonstrated four of the most commonly accepted predictors of poor outcome following shunt surgery.
One additional patient had an asymptomatic hidrocevalia collection self-limiting hygroma during the months after shunt placement. A highly significant improvement was seen in gait and sphincter functioning as well as in almost all daily life activity and functional scales.
Surgical Management Protocol The surgical management protocol, which hidrpcefalia recently been reported, 24 included several peri- and postoperative maneuvers to minimize secondary complications. To our knowledge, no study has been focused on the outcome in patients with NPH who hideocefalia accepted markers of poor prognosis prior to surgery. 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.
We selected a subgroup of patients who demonstrated four of the most commonly accepted predictors of poor outcome following shunt surgery. Neuropsychological Assessment and Daily 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.
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. The decision to implant a shunt was based on continuous ICP monitoring and CSF dynamics studies the R out was determined by Katzman and Hussey’s 14 constant rate infusion test. Several other authors support the view that continuous ICP monitoring is the most useful diagnostic test in evaluating NPH.
The maximum score 15 points indicates normal functioning in the three domains. The main objective of this paper was to challenge the widespread belief that patients with the classic symptoms or signs of hidrocefaliq outcome cannot improve after shunt procedures, especially when more than one of these signs are present. CT of Evan’s index. Age, symptom duration, degree of preoperative dementia, and ventricular dilation were not definitively related to neuropsychological or functional changes after surgery when these factors were evaluated by an independent neuropsychologist; however, clinical or radiological factors classically associated with a poor prognosis are increasingly found in patients with suspected NPH or in those who have a mixed-type dementia NPH associated with other neurodegenerative disorders such as Alzheimer disease normotensuva vascular dementia.
Bar graphs demonstrating baseline conditions and clinical conditions after surgery according to the NPH scale. Media in category “Normal pressure hydrocephalus” The following 6 files are in this category, out of 6 total. The disease affects three main areas—gait, sphincter control, and cognitive functioning—which were evaluated according to the NPH scale Table 3.

All patients had some level of cognitive impairment Table 4. Because of this factor and the potential risks of the treatment, some authors still question whether the benefits of shunt insertion outweigh the risks.
The neuropsychological examination included tests of verbal and visual memory, speed of hidrocecalia processing, and frontal lobe functioning as well as a brief screening test for dementia.
Accordingly, each patient received one of the following classifications: Postsurgical Complications There was no treatment-related death. In five patients, this valve was combined with an infraclavicular gravity-compensating accessory NMT Neurosciences Implants S.
Hidrocefalia Normotensiva by Angel Aguado on Prezi
Subacute subdural hematoma was diagnosed in a patient before discharge from the hospital. A percentage of change between baseline hkdrocefalia postoperative conditions was also calculated as follows: The Wilcoxon matched-pairs signed-rank test was normotnesiva to compare presurgical and postsurgical data. 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.
Patients’ functional behavior and changes in daily life activities were evaluated using several rating scales: In addition, we considered patients older than 64 years only because age is considered one of the most significant variables in neurological recovery and can preclude aggressive treatment. Despite the trend toward improvement in attention and verbal memory, only four of the patients presented clinical cognitive amelioration. Future research on hydrocephalus should always include a detailed clinical description of the sample, with the diagnostic and surgical strategies used.
Conclusions In this study we selected a subgroup of patients with some of the traditionally accepted predictors of poor nrmotensiva. T he indications for placing shunts in patients with NPH syndrome are still controversial, because surgery in these fragile patients does not always lead to a good outcome or improve quality of life.
