Endovascular strategy for unruptured cerebral aneurysms

Area of Science:

• Neurosurgery
• Interventional Neurology
• Vascular Neurology

Background:

• The optimal management for unruptured intracranial aneurysms (UIAs) remains uncertain, unlike ruptured aneurysms.
• Treatment decisions for UIAs require balancing the risk of rupture against the risks associated with treatment.
• Factors influencing UIA natural history and treatment outcomes include patient history, aneurysm characteristics, and management strategy.

Purpose of the Study:

• To synthesize current evidence regarding indications for endovascular treatment (EVT) of UIAs.
• To provide guidance on when and how to perform EVT for unruptured intracranial aneurysms.
• To aid clinicians in making informed treatment decisions for asymptomatic UIAs.

Main Methods:

• Review of large multicenter studies from the past decade.
• Analysis of factors influencing UIA natural history and treatment outcomes.
• Synthesis of data to define criteria for EVT in UIAs.

Main Results:

• The decision to treat UIAs necessitates a careful risk-benefit analysis.
• Patient-specific factors and aneurysm morphology are critical in determining treatment strategy.
• Evidence synthesis aims to clarify optimal EVT indications for UIAs.

Conclusions:

• Endovascular treatment (EVT) is a viable option for select unruptured intracranial aneurysms (UIAs).
• Treatment indications should be individualized based on a comprehensive assessment of aneurysm and patient factors.
• Further research and consensus are needed to refine UIA management guidelines.
