Anesthesia Considerations and Intraoperative Monitoring During Surgery for Arteriovenous Malformations and Dural Arteriovenous Fistulas

Research output: Contribution to journalReview article

Abstract

The anesthetic considerations for surgical resection of arteriovenous malformations (AVMs) and dural arteriovenous fistulas (DAVFs) incorporate many principles that are common to craniotomies for other indications. However, a high-flow, low-resistance shunt results in chronic hypoperfusion of adjacent brain tissue that is vulnerable to ischemia and at high risk for hyperemia and hemorrhage as resection of the lesion redirects blood flow. A comprehensive understanding of AVM pathophysiology and rapidly titratable anesthetic and vasoactive agents allow the anesthesiologist to alter blood pressure targets as resection evolves for optimal patient outcome. Intensive management is continued post-operatively as the brain acclimatizes to new parameters.
