Computed tomography in aneurysmal subarachnoid haemorrhage

B A Bell, B E Kendall, L Symon

    Journal of Neurology, Neurosurgery, and Psychiatry

    Summary

    The amount of blood in basal cerebrospinal fluid cisterns on initial CT scans significantly predicts surgical outcomes in patients with aneurysmal subarachnoid hemorrhage. Other factors include patient grade, hypertension history, and vasospasm presence.

    Area of Science:

    • Neurosurgery
    • Neuroradiology
    • Neurology

    Background:

    • Aneurysmal subarachnoid hemorrhage (aSAH) is a critical neurological condition.
    • Early assessment of hemorrhage severity is crucial for predicting patient outcomes.
    • Computed Tomography (CT) is a primary diagnostic tool for aSAH.

    Purpose of the Study:

    • To quantify the amount of blood in basal cerebrospinal fluid (CSF) cisterns on initial CT scans.
    • To determine the correlation between blood volume in basal cisterns and surgical outcomes in aSAH patients.
    • To identify other predictors of surgical outcome in aSAH.

    Main Methods:

    • Review of initial CT scans from 76 patients diagnosed with aSAH.
    • Quantification of blood visible in the basal CSF cisterns.
    • Statistical analysis to assess correlations between blood quantity and various clinical factors with surgical outcomes.

    Main Results:

    • A significant correlation was found between the quantity of blood in basal CSF cisterns and the outcome of surgery.
    • The pre-operative grade of the patient was also a significant predictor of surgical outcome.
    • A history of pre-existing hypertension and the presence of angiographic vasospasm were identified as additional correlating factors.

    Conclusions:

    • The amount of blood in basal CSF cisterns on initial CT scans is a significant prognostic indicator for surgical outcomes in aSAH.
    • Hemorrhage burden, patient's pre-operative condition, and vascular complications influence surgical success in aSAH.
    • CT-based quantification of subarachnoid blood offers valuable prognostic information for managing aSAH.
