CSF hydrodynamics after subarachnoid hemorrhage.

    Summary

    Many patients experience subtle neurological issues after subarachnoid hemorrhage (SAH) recovery. This study found disturbed cerebrospinal fluid (CSF) hydrodynamics in a significant portion, suggesting it as a cause of post-SAH-encephalopathy.

    Area of Science:

    • Neurosurgery
    • Neurology
    • Cerebrospinal Fluid Dynamics

    Background:

    • Subarachnoid hemorrhage (SAH) can lead to long-term neurological deficits, termed post-SAH-encephalopathy.
    • The underlying causes of post-SAH-encephalopathy remain uncertain despite apparent clinical recovery.

    Purpose of the Study:

    • To investigate cerebrospinal fluid (CSF) hydrodynamics in patients recovering from aneurysmal subarachnoid hemorrhage.
    • To identify potential etiological factors for post-SAH-encephalopathy.

    Main Methods:

    • Prospective study of 47 patients post-aneurysmal surgery for SAH.
    • Evaluation of CSF hydrodynamics using infusion tests and isotope cisternography during the recovery phase.

    Main Results:

    • 11% of patients exhibited clinical, CSF dynamic, and radiological signs of normal pressure hydrocephalus (NPH), responding well to shunting.
    • 26% showed abnormal CSF hydrodynamics without overt NPH, suggesting subclinical disturbances.

    Conclusions:

    • Disturbed CSF hydrodynamics are prevalent in patients recovering from SAH.
    • Altered CSF hydrodynamics may be a significant etiological factor in the development of post-SAH-encephalopathy.
