Summary

Surgical outcomes for multiple intracranial aneurysms show that one-stage operations are recommended when feasible. Treatment strategies for multiple aneurysms vary based on location and presentation, with one-stage operations yielding favorable results.

Area of Science:

  • Neurosurgery
  • Vascular Neurology

Background:

  • Multiple intracranial aneurysms present complex surgical challenges.
  • Treatment outcomes for multiple aneurysms are often compared to single aneurysms.

Purpose of the Study:

  • To review the surgical outcomes of patients with multiple intracranial aneurysms.
  • To evaluate the efficacy of different surgical approaches for multiple aneurysms based on their location and presentation.

Main Methods:

  • Retrospective review of 221 patients with multiple intracranial aneurysms operated between 1988 and 1994.
  • Classification of patients into three groups based on aneurysm location: unilateral anterior circulation, bilateral anterior circulation, and involvement of posterior circulation.
  • Analysis of surgical strategies including one-stage, two-stage, and partial treatments, and correlation with patient outcomes.

Main Results:

  • One-stage operations were performed in 89.8% of unilateral anterior circulation aneurysms.
  • Partial treatment was common in bilateral anterior circulation and posterior circulation aneurysms (63.6% and 30%, respectively).
  • Overall, 51.1% of patients had excellent outcomes (no neurological deficit), 21.7% had good outcomes (independent life), 14.5% had fair outcomes (assisted life), and 12.7% died.

Conclusions:

  • One-stage surgical operations are recommended for treating multiple intracranial aneurysms whenever possible.
  • Surgical management is the preferred treatment for unruptured multiple aneurysms.
  • For poor-grade subarachnoid hemorrhage patients or elderly individuals with unruptured multiple aneurysms, staged or partial treatment may be considered.
