Functional brain mapping optimization during awake craniotomy

Ammonia encephalopathy and awake craniotomy for brain language mapping: cause of failed awake craniotomy.

We report the case of an aborted awake craniotomy for a left frontotemporoinsular glioma due to ammonia encephalopathy on a patient taking Levetiracetam, valproic acid and clobazam. This awake mapping surgery was scheduled as a second-stage procedure following partial resection eight days earlier under general anesthesia. We planned to perform the surgery with local anesthesia and sedation with...

Ammonia encephalopathy and awake craniotomy for brain language mapping: Cause of failed awake craniotomy

Initial Experience with Brain Mapping under Awake Craniotomy for Resection of Insular Gliomas of the Dominant Hemisphere

Background & Importance: Insular lobe is located at the depth of sylvian fissure and is hidden by frontal, temporal and parietal lobes in close vicinity of internal capsule and basal ganglia and adjacent to the speech centers in the dominant hemisphere. Thus, radical resection of insular gliomas can be even more difficult. Brain mapping techniques can be used to maximize the extent of...

Awake craniotomy and electrophysiological mapping for eloquent area tumours.

OBJECTIVE An awake craniotomy facilitates radical excision of eloquent area gliomas and ensures neural integrity during the excision. The study describes our experience with 67 consecutive awake craniotomies for the excision of such tumours. METHODS Sixty-seven patients with gliomas in or adjacent to eloquent areas were included in this study. The patient was awake during the procedure and in...
