    Area of Science:

    • Neurosurgery
    • Anesthesiology

    Background:

    • Surgical removal of large arteriovenous malformations (AVMs) can be complex.
    • Deliberate hypotension is a technique used to reduce intraoperative bleeding.

    Observation:

    • A large AVM in the dominant parietal lobe required an extended surgical duration of 9.25 hours.
    • Sodium nitroprusside was utilized as the primary hypotensive agent throughout the procedure.

    Findings:

    • The prolonged use of sodium nitroprusside for deliberate hypotension was associated with a successful AVM removal.
    • Minimal neurological deficit was observed post-operatively, indicating the safety of the technique.
    • This represents the longest documented use of sodium nitroprusside for surgical hypotension.

    Implications:

    • Extended deliberate hypotension using sodium nitroprusside is a safe and effective strategy for complex AVM resection.
    • This case highlights the feasibility of prolonged hypotensive anesthesia in neurosurgery.
    • Careful dosage management is crucial for ensuring the safety of sodium nitroprusside in extended surgical durations.
