Papilloedema, CSF pressure, and CSF flow in cerebral tumours.

The presence or absence of papilloedema and the cisternal CSF pressure were compared with the RIHSA cisternograms in 24 patients with supratenotorial tumours. It was found that severe subarachnoid obstruction of CSF flow, leading to impaired CSF absorption at the superior sagittal sinus, was the main cause of raised CSF pressure and papilloedema associated with supratentorial tumours.

CSF hydrodynamic studies in man. 2 . Normal hydrodynamic variables related to CSF pressure and flow.

With the patient in the supine position, the subarachnoidal space was infused with artificial CSF at several constant pressure levels. The resulting flow of liquid was recorded. By draining CSF at a low pressure the CSF production rate was determined. Normal values are given and discussed for (1) the resting pressure, (2) the conductance of the CSF outflow pathways, (3) the formation rate of CS...

A Complexity Analysis for Normal Cerebral Blood and CSF Flow

Cerebro-spinal fluid (CSF) exhibits pulsatile flow due to systolic and diastolic blood flow in cerebral arteries and veins. We describe an investigation of the relationship between CSF flow and arterial & venous blood flow using principle component analysis (PCA). The study used Phase-Contrast Magnetic Resonance Images (PC-MRI) of 16 volunteers with no known CSF abnormalities. The immediate out...

Ventricular CSF immunoglobulins in brain tumours.

Ventricular CSF glucose, total protein, protein electrophoresis, IgG, IgA, IgM and CSF cytology were determined in thirty seven patients with brain tumours. CSF glucose was unchanged and total protein was significantly high. Protein electrophoresis showed higher albumin and gamma globulin fractions. Mean IgG and IgA were significantly higher (P less than 0.001) in malignant tumours than in beni...

CSF flow measurement in syringomyelia.

BACKGROUND AND PURPOSE CSF circulation has been reported to represent a major factor in the pathophysiology of syringomyelia. Our purpose was to determine the CSF flow patterns in spinal cord cysts and in the subararachnoid space in patients with syringomyelia associated with Chiari I malformation and to evaluate the modifications of the flow resulting from surgery. METHODS Eighteen patients ...
