    Post-surgery, elevated adrenaline and noradrenaline levels indicate cerebral vasospasm risk after aneurysm clipping. Specific patterns predict local versus generalized vasospasm, aiding early detection.

    Area of Science:

    • Neurosurgery
    • Vascular Neurology
    • Clinical Biochemistry

    Background:

    • Cerebral vasospasm is a serious complication following subarachnoid hemorrhage and aneurysm clipping.
    • Early detection and management of vasospasm are crucial for improving patient outcomes.
    • The role of plasma catecholamines in predicting post-operative vasospasm requires further elucidation.

    Purpose of the Study:

    • To investigate the relationship between plasma catecholamine concentrations and the development of cerebral vasospasm after intracranial aneurysm clipping.
    • To determine if specific catecholamine patterns can predict the type (local vs. generalized) of cerebral vasospasm.

    Main Methods:

    • Sequential measurement of plasma adrenaline and noradrenaline concentrations in 11 patients undergoing aneurysm clipping.

  • Correlation of catecholamine levels with the occurrence and type of cerebral vasospasm, confirmed by radiological evidence.

    • Main Results:

    • Patients developing local cerebral vasospasm exhibited a sustained increase in plasma catecholamines, especially noradrenaline.
    • Patients with generalized cerebral vasospasm showed early, high peaks in both adrenaline and noradrenaline preceding radiological diagnosis.

    Conclusions:

    • Plasma catecholamine levels, particularly their temporal patterns, may serve as early biomarkers for cerebral vasospasm post-aneurysm surgery.
    • Distinct catecholamine profiles are associated with local versus generalized cerebral vasospasm, offering potential for differential diagnosis.
