Objective:

To evaluate the quantitative changes in intracranial pressure (ICP) during various surgical phases in patients with acute subdural hematoma.

Approach:
    Key Findings:
    • ICP was recorded at 42 mmHg during burr hole placement, 39 mmHg during partial craniotomy, 20 mmHg during complete craniotomy, 14 mmHg during dural incision, and 9 mmHg during hematoma evacuation.
    • Each surgical phase resulted in a quantifiable reduction in ICP.
    Interpretation:

    The case illustrates the sequential impact of surgical interventions on ICP reduction in acute subdural hematoma.

    Limitations:
    • The study is based on a single case, limiting the generalizability of the findings.
    • The adverse clinical outcome of the patient may affect the interpretation of the results.
    Conclusion:

    The findings provide insights into the decompressive effects of surgical phases on ICP.
