Summary
Direct surgical clipping of basilar bifurcation aneurysms offers good outcomes. This study of 123 patients shows 85% good results, highlighting the effectiveness of direct operative management for these challenging neurosurgical cases.
Area of Science:
- Neurosurgery
- Vascular Surgery
- Cerebrovascular Disease
Background:
- Basilar bifurcation aneurysms present significant surgical challenges due to their deep location and proximity to critical neurovascular structures.
- Direct clipping is considered the gold standard for treating these aneurysms, enabling sac exclusion, decompression, and flow preservation.
Purpose of the Study:
- To report the outcomes of direct operative management for basilar bifurcation aneurysms.
- To evaluate the efficacy and safety of surgical approaches for these complex cerebrovascular lesions.
Main Methods:
- A retrospective review of 123 consecutive patients undergoing direct surgical management of basilar bifurcation aneurysms between January 1977 and December 1995.
- Surgical approaches included pterional and subtemporal methods, with a shift towards a modified pterional (temporopolar) approach from 1987 onwards.
Main Results:
- The study achieved an 85% good outcome rate among the 123 patients.
- Morbidity was reported at 8.1%, and mortality was 6.5% over the study period.
Conclusions:
- Direct operative management, particularly with evolving surgical techniques like the modified pterional approach, is an effective treatment for basilar bifurcation aneurysms.
- The findings support direct clipping as a viable and successful strategy for managing these complex aneurysms with acceptable morbidity and mortality rates.
