This study will determine the level of association between the quantitative estimates of brain uptake of [18F]flutemetamol and the quantitative immunohistochemical estimates of amyloid levels in biopsy samples previously obtained during shunt placement in patients who have normal pressure hydrocephalus (NPH).
The purpose of this study is to determine if usage of early lumbar drainage leads to less shunt surgery and less catheter associated complications in patients with communicating hydrocephalus after intracerebral hemorrhage with severe ventricular involvement.
Shunt failure remains a significant problem in pediatric patients with hydrocephalus. If reliable techniques for the accurate placement of ventricular catheters can be developed, shunt survival may improve. The purpose of this study is to assess the efficacy and safety of the ultrasound guided shunt insertion technique in the hands of experienced surgeons. The primary outcome measure is ventricular catheter location determined from post-operative brain images. The study is being conducted by the Hydrocephalus Clinical Research Network (HCRN), a network established to conduct multi-institutional clinical trials on pediatric hydrocephalus. Pediatric neurosurgeons at HCRN centers enrolled in this study will perform either ultrasound guided shunt surgery or a conventional shunt surgery. Patients who undergo conventional shunt surgery will serve as a contemporary control group.
The purpose of this study is to test and compare the efficacy of Endoscopic Third Ventriculostomy with shunting of Cerebrospinal fluid (CSF)for treatment for patients of Normal pressure Hydrocephalus.
The purpose of this study is to use transcranial Doppler (TCD) to predict intracranial pressure (ICP) and clinical outcome of neurocritical patients.
Intraventricular hemorrhage remains the most frequent, severe neurological complication of prematurity, occurring in 25-30% of preterm infants. Post-hemorrhagic ventricular dilation (PHVD) occurs in 25-50% of those infants, with over half requiring ventriculoperitoneal shunts. When suboptimally untreated, PVHD results in a 3-4 fold increase in neurodevelopmental delay. Despite the lifelong impact of PHVD on quality of life, little research has been done over the past 20 years to improve patient outcomes. The CENTRAL HYPOTHESIS of this project is that early treatment of PHVD will reduce shunt-dependence and improve neurodevelopmental outcome in preterm infants.
The purpose of the study is to determine the predictive values and prognostic accuracies of CSF dynamic measures, the TAP -TEST (high-volume cerebrospinal fluid withdrawal), resistance to CSF outflow and compliance in the prediction of shunt-treatment outcome in patients with idiopathic normal pressure hydrocephalus.
This study compares the accuracy of fast magnetic resonance imaging (MRI) using the half Fourier single shot rapid acceleration with relaxation enhancement technique to ultrasound in the diagnosis of fetal abnormalities. The investigators' specific aim is to perform MRI examinations with ultrafast MRI on fetuses with sonographic morphologic abnormalities. The investigators' hypotheses are that 1) MRI will demonstrate fetal morphologic abnormalities; and 2) MRI will add additional information to the sonographic diagnosis which may directly affect maternal and/or neonatal care.
The purpose of this study is to examine the role of ShuntCheck and MR Imaging in evaluating the presence or absence of Shunt Obstruction in the patients of Hydrocephalus or Idiopathic Intracranial Hypertension (IIH) undergoing radionuclide test for suspected shunt obstruction. This is an exploratory study to determine how a non-invasive device can assist in detection of presence of flow in these patients.
