Early operation for ruptured intracranial aneurysms: comparative study with computed tomography.

    Summary

    Early surgery for ruptured intracranial aneurysms showed a link between CT findings and outcomes. High density on CT scans correlated with surgical results and vasospasm, suggesting drainage may help severe cases.

    Area of Science:

    • Neurosurgery
    • Neuroradiology
    • Neurology

    Background:

    • Ruptured intracranial aneurysms pose significant risks.
    • Early surgical intervention is a critical treatment modality.
    • Preoperative computed tomographic (CT) findings may influence surgical outcomes.

    Purpose of the Study:

    • To investigate the correlation between preoperative CT findings and the results of early surgical intervention for ruptured intracranial aneurysms.
    • To identify CT indicators that predict surgical outcomes and complications such as vasospasm.

    Main Methods:

    • Retrospective analysis of 72 patients undergoing early surgery for ruptured intracranial aneurysms.
    • Correlation of surgical outcomes with preoperative CT scan findings, including density and clot distribution.

    Related Experiment Videos

  • Assessment of symptomatic vasospasm and ventricular enlargement in relation to CT results.

    • Main Results:

    • A significant correlation was observed between surgical outcomes, symptomatic vasospasm, and high density on preoperative CT scans, especially a localized thick subarachnoid clot.
    • No relationship was found between preoperative CT findings and the occurrence of ventricular enlargement.
    • Cisternal or ventricular drainage may improve postoperative course in patients with severe subarachnoid clot.

    Conclusions:

    • Preoperative CT findings, particularly localized high density in the subarachnoid space, are predictive of surgical results and vasospasm risk in ruptured intracranial aneurysms.
    • Ventricular enlargement on preoperative CT does not appear to correlate with surgical outcomes.
    • Consideration of cisternal or ventricular drainage for patients with extensive subarachnoid hemorrhage may mitigate postoperative complications.
