OBJECT The goal of this prospective study was to compare outcome after placement of a low- or medium-pressure shunt in patients with normal-pressure hydrocephalus (NPH). METHODS Ninety-six patients with NPH were randomized to receive a low-pressure ventriculoperitoneal shunt (LPV; 40 +/- 10 mm H2O) or medium high-pressure ventriculoperitoneal shunt (MPV;(More)
OBJECT An important complication of external CSF drainage is bacterial meningitis or ventriculitis, resulting in increased morbidity, mortality, and health care costs. In 2003, a high rate (37%) of probable drain-related infections was identified at the authors' hospital. A multidisciplinary working group was installed to reduce this incidence to < 10%(More)
We present the baseline characteristics of 101 patients with normal pressure hydrocephalus (NPH), entering a study that evaluates the diagnostic reliability of CSF outflow resistance. Patients were assessed by a gait scale consisting of 10 features of walking and the number of steps and seconds necessary for 10 m, a dementia scale comprising the 10 word(More)
The authors examined whether measurement of resistance to outflow of cerebrospinal fluid (Rcsf) predicts outcome after shunting for patients with normal-pressure hydrocephalus (NPH). In four centers 101 patients (most of whom had idiopathic NPH) who fulfilled strict entry criteria underwent shunt placement irrespective of their level of Rcsf obtained by(More)
OBJECT Progressive hydrocephalus may lead to edema of the periventricular white matter and to damage of the brain parenchyma because of compression, stretching, and ischemia. The aim of the present study was to investigate whether cerebral edema can be quantified using diffusion-weighted imaging in infants with hydrocephalus and whether CSF diversion could(More)
The value of the measurements of CSF outflow resistance (Rcsf) relative to predicting outcome after shunting was studied. In a group of 101 patients with mainly idiopathic normal pressure hydrocephalus (NPH) Rcsf was obtained by lumbar constant flow infusion. Gait disturbance and dementia were quantified using an NPH scale (NPHS) and disability by the(More)
The effect of raised intracranial pressure (ICP), due to infantile hydrocephalus, on the process of myelination has been suggested in the literature. In this study 19 hydrocephalic infants were followed-up with anterior fontanelle pressure (AFP) measurement (assessment of ICP), MRI (assessment of the myelination process and the CSF volume), and(More)
OBJECT The objectives of this study were to assess, in a cohort of children with recently treated hydrocephalus, the correlation between scores on the Hydrocephalus Outcome Questionnaire (HOQ) and the children's type of schooling and motor functioning, and to assess the overall outcome of the children. METHODS The health status of 142 pediatric patients(More)
OBJECTIVE Robotic surgery systems were introduced recently with the objective of enhancing the dexterity and view during procedures that use a videoscope. The first case report of robot-assisted thoracoscopic removal of a benign neurogenic tumor in the thorax is presented. METHODS A 46-year-old woman presented with a history of paravertebral pain. A chest(More)
Cerebral hemodynamic changes in infants with progressive hydrocephalus have been studied with the transcranial Doppler (TCD) technique. Several authors have referred to the correlation between the hemodynamic changes and increased intracranial pressure (ICP). Despite conflicting conclusions on the value of pulsatility index (PI) and resistance index (RI)(More)
