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.
