The surgical results obtained with a cerebrospinal fluid (CSF) shunt operation in 13 patients considered to be suffering from normal pressure hydrocephalus have been correlated with the findings of the constant manometric infusion test (IT) and of prolonged intracranial pressure recordings. A positive ...
Complications include obstruction of cerebral spinal fluid (malfunction) and infection. Morbidity and mortality rates are high when shunt malfunction and infection are not treated emergently. This report summarizes the physical examination of patients with ventricular shunts, reviews the type of shunts ...
Following the Monro-Kellie doctrine, the Cerebral Blood Volume Changes (CB_VC) should be mirrored by the Cerebrospinal Fluid Volume Changes (CSF_VC) at the spinal canal. Cervical level is often chosen to estimate CB_VC during the cardiac cycle. However,
In humans the phase lag from the artery expansion to the spinal canal at C2 level is + 5.1 ± 10.5°33. The phase lag in the sagittal sinus is –50° after the arterial pulse27, giving a phase difference of 55° between the spinal canal pulsation and the cortical vein ...
