Computerized tomography and prognosis in early aneurysm surgery.

L M Auer, G H Schneider, T Auer

    Journal of Neurosurgery
    |August 1, 1986
    PubMed
    Summary

    Computerized tomography (CT) scans reveal that early findings of subarachnoid hemorrhage (SAH) predict patient outcomes. CT scan results are more valuable than clinical grading for predicting recovery after cerebral aneurysm treatment.

    Area of Science:

    • Neurosurgery
    • Radiology
    • Neurology

    Background:

    • Ruptured saccular cerebral aneurysms can lead to subarachnoid hemorrhage (SAH).
    • Early diagnosis and surgical intervention are crucial for managing SAH.
    • Calcium antagonists like nimodipine are used in treatment.

    Purpose of the Study:

    • To evaluate the prognostic value of preoperative computerized tomography (CT) findings in patients with ruptured saccular cerebral aneurysms.
    • To compare the predictive power of CT findings with clinical grading (Hunt and Hess) for patient outcomes.

    Main Methods:

    • A consecutive series of 100 patients with ruptured saccular cerebral aneurysms were studied.
    • All patients underwent diagnosis and surgery within 72 hours of subarachnoid hemorrhage (SAH).

  • Computerized tomography (CT) scans were used to assess the severity of SAH and identify associated hemorrhages. Patients received nimodipine treatment.

    • Main Results:

    • Preoperative CT scans showed SAH severity ranging from minor to severe.
    • Postoperative CT scans indicated a significant reduction in SAH in most patients.
    • A good outcome (no or minimal deficit) was observed in 93% of patients with SAH only and good preoperative neurological grade.
    • Patients with additional intracerebral or intraventricular hemorrhage had a significantly lower good outcome rate (44%).
    • Delayed ischemic neurological symptoms due to vasospasm occurred in 2% of patients.

    Conclusions:

    • Morphological preoperative CT findings are valuable prognostic indicators in ruptured saccular cerebral aneurysms.
    • CT scan findings may be superior to clinical grading in predicting patient outcomes.
    • Early CT assessment aids in tailoring treatment and predicting recovery after SAH.
