Hydrocephalus following aneurysmal SAH.

A Spallone, F M Gagliardi

    Zentralblatt Fur Neurochirurgie
    |January 1, 1983
    PubMed
    Summary

    Combination antifibrinolytic therapy, including tranexamic acid (AMCA) and aprotinin, reduced hydrocephalus formation after subarachnoid hemorrhage compared to AMCA alone. This suggests a link between erythrocyte breakdown products and hydrocephalus development.

    Area of Science:

    • Neurosurgery
    • Neurology
    • Pharmacology

    Background:

    • Subarachnoid hemorrhage (SAH) frequently leads to hydrocephalus.
    • Antifibrinolytic therapy is used to manage SAH complications.
    • The precise mechanisms linking SAH, antifibrinolytics, and hydrocephalus remain under investigation.

    Purpose of the Study:

    • To compare the efficacy of two antifibrinolytic regimens in preventing hydrocephalus after SAH.
    • To investigate factors influencing hydrocephalus development post-SAH.
    • To explore the relationship between ischemic complications and hydrocephalus.

    Main Methods:

    • Two patient groups received different antifibrinolytic treatments: Group A (AMCA + aprotinin) and Group B (AMCA alone).
    • Hydrocephalus formation and ischemic complications were monitored.
    • Statistical analysis was performed to identify correlations between various factors and outcomes.

    Main Results:

    • Group A demonstrated significantly lower rates of hydrocephalus and ischemic complications compared to Group B.
    • Neurological condition, hemorrhage severity, and aneurysm location influenced hydrocephalus development.
    • A strong correlation was observed between preceding ischemic complications and hydrocephalus (p < 0.005).
    • Antihypertensive use increased ischemic complications but did not affect hydrocephalus rates.

    Conclusions:

    • Combination therapy with AMCA and aprotinin appears more effective in preventing hydrocephalus post-SAH.
    • Erythrocyte decomposition products are hypothesized as a key factor in the pathogenesis of cerebral ischemia and hydrocephalus after SAH.
    • The study does not support periventricular ischemia as the primary cause of hydrocephalus following SAH.
