Summary

Two cases of subarachnoid hemorrhage resulted from anterior communicating artery complex aneurysms. These occurred during balloon occlusions for giant internal carotid artery aneurysms.

Area of Science:

  • Neurology
  • Neurosurgery
  • Vascular Medicine

Background:

  • Giant aneurysms of the internal carotid artery often pose treatment challenges.
  • Balloon occlusion is a technique used for managing unclippable aneurysms.
  • Anterior communicating artery complex aneurysms are a subset of cerebrovascular diseases.

Observation:

  • Two patients developed subarachnoid hemorrhage.
  • The hemorrhage was attributed to aneurysm development and enlargement.
  • These events occurred within a cohort of 58 patients undergoing balloon occlusion therapy.

Findings:

  • Aneurysm development and enlargement in the anterior communicating artery complex can lead to subarachnoid hemorrhage.
  • This complication was observed in the context of treating complex internal carotid artery aneurysms.

Implications:

  • Highlights potential risks associated with endovascular treatment of complex aneurysms.
  • Suggests careful monitoring for aneurysm changes post-procedure.
  • Informs risk-benefit analysis for balloon occlusion in specific aneurysm types.
