Subarachnoid hemorrhage precipitated by cocaine snorting.

P J Lichtenfeld, D B Rubin, R S Feldman

    Archives of Neurology
    |February 1, 1984
    PubMed
    Summary

    Cocaine use, specifically snorting, can rapidly cause subarachnoid hemorrhage, a dangerous brain bleed. This study reports two cases linked to cocaine abuse, highlighting a previously unrecognized risk.

    Area of Science:

    • Neurology
    • Toxicology
    • Cardiovascular Science

    Background:

    • Subarachnoid hemorrhage (SAH) is a critical neurological emergency often associated with vascular abnormalities.
    • Cocaine abuse is a known risk factor for various cardiovascular and cerebrovascular events.
    • The acute effects of intranasal cocaine on cerebral vasculature require further elucidation.

    Observation:

    • Two patients presented with sudden, severe headache consistent with SAH shortly after intranasal cocaine use.
    • Case 1 involved bleeding from an anterior communicating artery aneurysm.
    • Case 2 involved hemorrhage from a temporoparietal arteriovenous malformation.

    Findings:

    • The temporal association between cocaine snorting and the onset of SAH was striking in both cases.
    • This suggests a potential direct or indirect mechanism by which cocaine may trigger or exacerbate vascular rupture.
    • These cases represent a previously unreported association between cocaine abuse and subarachnoid hemorrhage.

    Implications:

    • Clinicians should consider cocaine abuse in the differential diagnosis of patients presenting with SAH, especially younger individuals.
    • Public health awareness regarding the cerebrovascular risks of cocaine use, including SAH, is crucial.
    • Further research is warranted to understand the pathophysiology linking cocaine use to subarachnoid hemorrhage.
