Resection of Brainstem Cavernous Malformations: Pearls and Pitfalls for Minimizing Complications.
BACKGROUND: Surgical management of brainstem cavernous malformations (CMs) is a controversial topic in the field of neurosurgery. These lesions have a propensity to hemorrhage, thereby disrupting surrounding brainstem eloquence.
METHODS: This article provides the personal reflections of the senior author and a narrative literature review on resection of brainstem CMs.
RESULTS: Here we discuss the indications for microsurgery, microsurgical techniques and nuances, and perioperative management considerations necessary to minimize complications during resection of brainstem CMs, which are lesions of venous origin.
CONCLUSIONS: The natural history of the lesion, risk of future hemorrhage, and potential for symptom resolution should be carefully considered when planning to resect brainstem CMs. Nuanced microsurgical techniques with minimal disruption of normal tissues provide the best chance of satisfactory outcomes.
