Summary
Surgical treatment of paraclinoidal aneurysms, located near the cavernous sinus, presents unique challenges. A new anatomical classification aids in individualized surgical approaches, leading to good outcomes for most patients.
Area of Science:
- Neurosurgery
- Vascular Neurology
- Cerebrovascular Surgery
Background:
- Paraclinoidal aneurysms pose significant surgical challenges due to their location.
- These aneurysms often lack clear origins or hemodynamic causes, complicating traditional surgical strategies.
Purpose of the Study:
- To present a classification system for paraclinoidal aneurysms.
- To analyze surgical outcomes for paraclinoidal aneurysms treated at a single institution.
Main Methods:
- Retrospective review of 89 patients with paraclinoidal aneurysms.
- Surgical treatment involving temporary/permanent carotid artery occlusion and hypothermic circulatory arrest.
- Classification based on aneurysm projection: carotid-ophthalmic, superior hypophyseal, and proximal posterior carotid artery wall.
Main Results:
- 89 patients treated, 44% presented with subarachnoid hemorrhage.
- 38% had multiple vascular anomalies.
- Good outcomes achieved in 86.5% of patients, with one death.
Conclusions:
- A practical anatomical grouping of paraclinoidal aneurysms is feasible.
- Individualized surgical approaches based on aneurysm projection improve outcomes.
- Effective management of these complex aneurysms is achievable with good visual function preservation.
