The relationship between CSF circulation and cerebrovascular pressure-reactivity in normal pressure hydrocephalus.
OBJECTIVE Previously, we documented association between CSF circulation and transcranial-Doppler derived autoregulation in non-shunted patients suffering from hydrocephalus. In the present study we sought to investigate the relationship between the resistance to CSF outflow and pressure-reactivity both in shunted and non-shunted NPH patients. MATERIAL AND METHODS Sixty-eight patients (47 non-...
متن کاملDecompensated chronic congenital hydrocephalus.
A 66 year-old woman with congenital macro cephaly and developmental delay presented with aphasia and right-sided weakness. Head CT revealed severe hydrocephalus of the lateral and third ventricles with a normal fourth ventricle due to a chronic congenital process (Fig. 1A). MRI confirmed subacute embolic infarcts of the left middle cerebral artery territory (Fig. 1B) and a heparin drip was init...
متن کاملExternal hydrocephalus. Early finding in congenital communicating hydrocephalus.
Dilation of the subarachnoid channels overlying the cerebral hemispheres, ie, external hydrocephalus, can be an early anatomic-radiologic finding in some infants with congenital communicating hydrocephalus. This structural change may progress to ventricular dilation or internal hydrocephalus. Enlargement of the subarachnoid channels appears to occur during the first stage in the development of ...
متن کاملIntracerebral microdialysis and CSF hydrodynamics in idiopathic adult hydrocephalus syndrome.
BACKGROUND In idiopathic adult hydrocephalus syndrome (IAHS), a pathophysiological model of "chronic ischaemia" caused by an arteriosclerotic process in association with a CSF hydrodynamic disturbance has been proposed. OBJECTIVE To investigate whether CSF hydrodynamic manipulation has an impact on biochemical markers related to ischaemia, brain tissue oxygen tension (PtiO(2)), and intracrani...
متن کاملCSF spaces in idiopathic normal pressure hydrocephalus: morphology and volumetry.
PURPOSE Idiopathic normal pressure hydrocephalus (NPH) is an important cause of dementia in the elderly; however, idiopathic NPH is often difficult to differentiate from normal aging and vascular dementias in which brain atrophy with ventricular dilatation (hydrocephalus ex vacuo or central atrophy) is present. To elucidate the distinctive features of the distribution of CSF in idiopathic NPH, ...
