Giant intracranial aneurysms: endovascular challenges

Area of Science:

• Vascular Surgery
• Interventional Neurology
• Medical Device Technology

Background:

• Giant aneurysms present complex therapeutic challenges for both surgical and endovascular approaches.
• Traditional endovascular coiling as a primary treatment for giant aneurysms has yielded suboptimal occlusion and durability rates.
• Existing literature highlights limitations in current endovascular methods for managing these complex vascular lesions.

Purpose of the Study:

• To review endovascular treatment strategies for giant aneurysms published after 1994.
• To evaluate the efficacy, safety, and durability of various endovascular techniques, including deconstructive and reconstructive methods.
• To assess the impact of technological advancements on endovascular treatment outcomes for giant aneurysms.

Main Methods:

• Comprehensive literature review of endovascular treatment strategies for giant aneurysms.
• Analysis of studies published after the FDA approval of Guglielmi detachable coils in 1994.
• Inclusion of data on follow-up, durability, and occlusion rates where available.

Main Results:

• Endovascular coiling as a standalone therapy for giant aneurysms has shown disappointing results.
• Hunterian strategies have demonstrated greater success in published series.
• Recent advancements in coil, glue, and stent technology show significant promise for reconstructive parent vessel techniques.

Conclusions:

• Parent vessel reconstruction using advanced endovascular technologies offers a promising approach for giant aneurysms.
• These newer techniques aim for acceptable morbidity, mortality, and long-term durability.
• Continued innovation in endovascular technology is crucial for improving giant aneurysm management.
