Area of Science:

  • Neurosurgery
  • Neurology
  • Vascular Surgery

Background:

  • Intracranial aneurysm surgery frequently requires temporary cerebral ischemia.
  • This procedure aims to reduce risks during dissection, clipping, or vascular reconstruction.

Purpose of the Study:

  • To review the concepts of ischemic thresholds in neurosurgery.
  • To examine physiological variables impacting outcomes after ischemic episodes.
  • To survey available and developing protective agents against ischemic brain injury.

Main Methods:

  • Literature review of concepts related to cerebral ischemia.
  • Analysis of physiological factors influencing outcomes.
  • Examination of pharmacological neuroprotective agents.

Main Results:

  • Understanding ischemic thresholds is crucial for patient management.
  • Physiological variables significantly affect the extent of ischemic injury.
  • Various neuroprotective agents show promise in limiting brain damage.

Conclusions:

  • Effective management of temporary cerebral ischemia is vital in intracranial aneurysm surgery.
  • Further research into neuroprotective agents can improve patient outcomes.
  • Optimizing physiological parameters can mitigate risks associated with ischemic episodes.
