Pressure in the sagittal sinus during intracranial hypertension in man

摘要: ✓ Intracranial pressure (ICP) and sagittal sinus (SSP) were measured simultaneously in 12 patients with brain tumors secondary intracranial hypertension (ICH). In nine, the mean SSP was largely unaffected by changes ICP. three, changed all but one patient, ICP remained higher than and, as increased, difference between two also increased. Sinograms performed during ICH demonstrated partial collapse of sinuses some not others. The adults appears to respond unpredictably Since rate cerebrospinal fluid drainage depends upon gradient SSP, spatial compensation is probably influenced response Individuals gradients that rapidly increase because their do compensate more those whose collapse. This assumed may account...
