Basilar apex artery aneurysm clipping: how I do it

Area of Science:

• Neurosurgery
• Vascular Neurology

Background:

• Basilar artery apex (BAA) aneurysms account for 5-8% of intracranial aneurysms.
• Ruptured BAA aneurysms carry high rates of morbidity and mortality due to their critical location in the posterior circulation and brainstem supply.

Purpose of the Study:

• To describe the institutional perioperative protocol for managing basilar artery apex aneurysms.
• To focus on surgical anatomy, approach selection, and intraoperative nuances for complex BAA aneurysms.

Main Methods:

• Review of institutional perioperative protocol for basilar artery apex aneurysm management.
• Detailed analysis of surgical anatomy relevant to BAA aneurysms.
• Discussion of approach selection and intraoperative techniques for microsurgical occlusion.

Main Results:

• The protocol emphasizes detailed understanding of surgical anatomy for BAA aneurysm management.
• Approach selection and intraoperative nuances are critical for successful microsurgical occlusion.
• Endovascular techniques are favored, but surgical expertise remains vital for complex cases.

Conclusions:

• A structured perioperative protocol is essential for managing complex basilar artery apex aneurysms.
• Microsurgical occlusion remains a necessary treatment option, requiring specialized anatomical knowledge and surgical skill.
• This protocol aims to optimize outcomes for patients with these challenging aneurysms.
