    Temporary arterial occlusion is a safe technique in cerebral aneurysm surgery, not increasing mortality or morbidity. This method aids neurosurgeons in managing complex cases, ensuring safer dissection and reducing hemorrhage risks.

    Area of Science:

    • Neurosurgery
    • Vascular Surgery
    • Neurology

    Background:

    • Premature rupture of cerebral aneurysms during surgery presents significant risks.
    • Hemorrhage control with direct pressure or suction can be challenging, potentially leading to vital structure injury.
    • Temporary arterial occlusion offers a strategic advantage in managing these surgical hazards.

    Purpose of the Study:

    • To evaluate the safety and efficacy of elective temporary arterial occlusion in intracranial aneurysm surgery.
    • To assess the impact of temporary occlusion on patient outcomes, including mortality and morbidity.
    • To determine if temporary occlusion increases overall risks compared to standard surgical approaches.

    Main Methods:

    • Retrospective review of 185 intracranial aneurysm surgeries performed between January 1980 and January 1985.

  • Analysis of 66 patients who underwent temporary arterial occlusion versus 119 patients who did not.
  • Comparison of clinical outcomes, including excellent, good, fair, and poor results, and mortality rates between the two groups.

    • Main Results:

    • Temporary arterial occlusion was used in 35.7% of the cases.
    • Excellent outcomes were achieved in 65.2% of patients, with a 6.1% mortality rate overall.
    • No significant difference in outcomes or mortality was observed between patients with and without temporary arterial occlusion.

    Conclusions:

    • Temporary arterial occlusion is a valuable adjunct in neurosurgery for intracranial aneurysms, particularly in complex cases.
    • When used judiciously, temporary occlusion does not appear to increase overall mortality or morbidity.
    • This technique can facilitate safer dissection by reducing tension within the aneurysm sac.
