[Monitored Anesthesia Care for Deep Brain Stimulation and Embolization of Brain Arteriovenous Malformation].

The aim of monitored anesthesia care (MAC) in neurosurgery and interventional neuroradiology is to provide optimal surgical conditions including patient immobility and comfort, facilitate intraoperative neuromonitoring, and rapidly treat any complication. The anesthetist has a crucial role in facilitating procedures, and this requires an understanding of specific procedures, their potential complications, and their management. Choice of anesthetic technique varies between centers with little data to support any specific technique. Dexmedetomidine is useful as a sedative and hypnotic for patients undergoing procedures without the need for tracheal intubation. We usually use dexmedetomidine in MAC.
