Posterior Circulation Aneurysms.

Area of Science:

• Neurosurgery
• Cerebrovascular Diseases
• Interventional Neuroradiology

Background:

• Posterior circulation aneurysms exhibit a higher rupture and symptomatic presentation rate compared to anterior circulation counterparts.
• Diverse treatment modalities exist, encompassing microsurgical clipping, trapping with bypass, wrapping, and various endovascular techniques (coiling, stent-assisted coiling, flow diversion, vessel sacrifice).

Purpose of the Study:

• To discuss the ongoing controversy surrounding surgical versus endovascular treatment of posterior circulation aneurysms.
• To highlight the importance of multidisciplinary assessment in guiding treatment strategies for these complex vascular lesions.

Main Methods:

• Review of current treatment modalities for posterior circulation aneurysms.
• Emphasis on multidisciplinary team approach involving surgeons skilled in both open microsurgery and endovascular techniques.
• Consideration of anatomical factors and individual patient characteristics in treatment planning.

Main Results:

• The choice between surgical and endovascular treatment for posterior circulation aneurysms remains a subject of debate in cerebrovascular neurosurgery.
• Advancements in both surgical and endovascular fields continue to fuel this discussion.

Conclusions:

• Multidisciplinary assessment is crucial for optimizing treatment strategies for posterior circulation aneurysms.
• Anatomical nuances and patient-specific factors are paramount in determining the optimal therapeutic approach.
• Proficiency in microsurgical techniques remains essential for managing these challenging aneurysms.
