“…Freund [15] reported that in the case of patients with post-traumatic syringomyelia, the mean velocity of their spine was 3.31 cm/s due to a narrowed spinal canal, which is significantly higher than that of a normal person (1.23 cm/s). Generally, the cerebrospinal fluid normally flows through the process, where the cerebrum pressurizes the cerebral ventricle inwardly and expands into the subarachnoid space outwardly during the systole.…”

Applicability of Assessing Narrowing of Spinal Canal Using Quantitative Analysis of CSF Flow

et al. 2012

This study evaluated an assessment tool for spinal canal stenosis by analyzing the speed and flow volume of the cerebrospinal fluid (CSF) in patients suffering from spinal canal stenosis, a representative chronic spinal disease. Twenty patients diagnosed with spinal canal stenosis from 1 November 2007 to 29 February 2008 were selected. Twenty applicants without a medical history or abnormalities in a psychological test were selected as the comparison group. The results showed that Applied Magnetic Resonance the change in the speed and flow volume of the CSF in the T-spine 4-5 and L-spine 1-2 and 4-5 levels was lower in the test group than that in the comparison group. On the other hand, the mean flow volume in the test group was higher in both directions than that of the comparison group.

“…The obstruction of the CSF pathways within the spinal cord can cause edema of the cervical cord (Sartoretti-Schefer et al 2000), thereby causing a secondary spinal cord injury. Using MRI phase-contrast studies, Freund found significantly impaired spinal CSF flow dynamics in four post-traumatic syringomyelia patients (Freund et al 2001). Another study revealed significantly decreased spinal cord motion and CSF circulation in the case of severe compression of the spinal cord and a good recovery postoperatively (Levy 1999).…”

The clinical application of non-invasive intracranial blood volume pulse wave monitoring

et al. 2005

An ultrasonic method was used to non-invasively measure intracranial blood volume (IBV) pulse waveforms. This technology has previously shown a strong association between invasively recorded ICP pulse waves and non-invasively recorded IBV pulse waves. The objective of the present study was to investigate the diagnostic value of non-invasively measured IBV pulse waves in the cases of different pathologies. A total of 75 patients were examined and these included cases of acute, chronic and stabilized hydrocephalus, spinal cord injury and terminal blood flow. These were compared to a control group of 53 healthy volunteers. The object of comparison was normalized and averaged IBV pulse waves. Pathological IBV pulse waveforms were compared with IBV pulse waveforms of the normal group using sub-wave values, the area under waveform curve and the Euclidean distance calculation. The non-invasively measured IBV pulse waveform is not significantly dependent on acoustic path, gender or age. A detectable change in IBV pulse waveform shape was observed in situations when disturbance in intracranial hydrodynamics was present, e.g. during hypoventilation tests, in cases of terminal blood flow and hydrocephaly, depicting the level of hydrocephalus activity and the patient's compensatory capabilities as well as the effect of treatment.

“…Turbulent, hyperdynamic CSF flow may be an additive factor for worsening myelopathy and the culprit for developing syringohydromyelia (SYM). Altered and exaggerated CSF flow patterns in the presence of spinal canal stenosis are known to lead to SYM . CSF pressure dissociation may affect the spinal cord differently rostral and caudal to the stenosis while maintaining more uniform pressure buildup across the SYM .…”

Derangements of septum posticum may present a spectrum of findings that should be considered in the differential of thoracic myelopathy. Flattening of the posterior cord margin is a reliable imaging clue for a dorsal extra-medullary compressive lesion. Cord compression results from combination of adhesive membranes and turbulent CSF flow. The clinical course may be difficult to predict. Periodic imaging follow up can be helpful to confirm stability of findings in expectantly managed cases.
