Awake craniotomy has been widely used for tumor resection, epilepsy surgery, deep brain stimulation, and carotid endarterectomy. The report on awake artery malformation clipping is rare, especially for anesthesia management.


A 62-year-old female diagnosed with malformation of anterior cerebral artery at the right side. We clipped the artery malformation with intraoperative neuromonitoring (IONM) in awake craniotomy. Spontaneous respiration was maintained throughout the procedure by nasopharyngeal airway during the surgery successfully.


The technique of monitoring anesthesia care can be performed successfully for the patient with IONM.

Keywords: Artery malformation, Awake craniotomy, Intraoperative neuromonitoring, Nasopharyngeal airway, Case report

Core Tip: In this case, due to the patient’s strong request for the integrity of motor function, the neurosurgeon explained the advantages and disadvantages of different surgery plans to her. This patient chose the awake craniotomy finally. Awake craniotomy was performed successfully in fully cooperative patient with stable neurological status.
