Resection of Brainstem Arteriovenous Malformations: Pearls and Pitfalls for Minimizing Complications.

The decision-making process surrounding resection of arteriovenous malformations (AVMs) in proximity to vital brainstem structures is a complex topic. Intricate vasculature in the setting of exquisite brainstem eloquence creates a high-risk operative landscape with the potential for devastating complications. Effective resections are driven by mastery of the relevant operative anatomy, preservation of pertinent vasculature, and technical experience and acumen. This article provides a narrative literature review on the resection of brainstem AVMs. Operative anatomy and approaches to AVMs of the midbrain (anterior/posterior), pons (anterior/lateral), and medulla (anterior/lateral) are discussed herein, with a focus on pearls and pitfalls for minimizing complications during resection. Careful consideration of the patient's clinical background, the natural history of the lesion, and expertise of the treating surgeon are paramount for improving the natural course of brainstem AVMs. [ABSTRACT FROM AUTHOR]
