Decision-Making for Patients With Cerebral Arteriovenous Malformations

Area of Science:

• Neurology
• Neurosurgery
• Vascular Neurology

Background:

• Cerebral arteriovenous malformations (AVMs) are complex vascular lesions with variable natural history.
• Management strategies for ruptured AVMs are established, but unruptured AVM treatment remains controversial.
• The A Randomized Trial of Unruptured Arteriovenous Malformations (ARUBA) trial has influenced but not resolved the debate due to limitations.

Purpose of the Study:

• To define the natural history of cerebral AVMs.
• To provide an overview of the ARUBA trial and its implications.
• To outline the current treatment paradigm for cerebral AVMs.

Main Methods:

• Literature review focusing on cerebral AVMs.
• Analysis of the ARUBA trial's findings and limitations.
• Synthesis of current evidence on AVM treatment options.

Main Results:

• Cerebral AVMs exhibit a heterogeneous natural history.
• The ARUBA trial provides insights but has limitations impacting its generalizability.
• Advances in treatment options enhance safety and efficacy.

Conclusions:

• Understanding AVM natural history is crucial for safe management.
• The ARUBA trial's applicability is limited, necessitating continued clinical judgment.
• Current treatment paradigms for cerebral AVMs are evolving with improved options.
