Recent studies show endovascular treatment for intracranial aneurysms offers better outcomes than surgery. However, more long-term data is needed to fully assess the risk-benefit ratio of endovascular coiling.

Area of Science:

  • Neurosurgery
  • Vascular Neurology
  • Interventional Neuroradiology

Background:

  • Intracranial aneurysms pose significant risks, necessitating evaluation of treatment efficacy.
  • Surgical and endovascular approaches are primary treatment modalities.
  • Recent clinical trials have generated debate regarding optimal management strategies.

Purpose of the Study:

  • To review recent literature on intracranial vascular surgery.
  • To summarize key findings from major trials.
  • To discuss the clinical implications of these findings.

Main Methods:

  • Literature review of recent studies in intracranial vascular surgery.
  • Analysis of findings from the International Study of Unruptured Intracranial Aneurysms (ISUIA).

  • Evaluation of results from the International Subarachnoid Aneurysm Trial (ISAT) and the Intraoperative Hypothermia for Aneurysm Surgery Trial (IHAST).

    • Main Results:

    • ISUIA reported low rupture rates for small unruptured aneurysms and favorable morbidity with endovascular treatment.
    • ISAT demonstrated superior one-year outcomes (survival free of disability) with endovascular coiling for ruptured aneurysms.
    • Preliminary IHAST results showed no significant difference between intraoperative hypothermia and normothermia for neuroprotection.

    Conclusions:

    • ISUIA and ISAT provide crucial data on aneurysm natural history and treatment outcomes.
    • Endovascular therapy shows comparable or better morbidity rates than surgery for aneurysms.
    • Long-term efficacy data for endovascular coiling is essential for a comprehensive risk-benefit assessment.
