Electrocorticographic frequency alteration mapping for extraoperative localization of speech cortex.
OBJECTIVE Electrocortical stimulation (ECS) has long been established for delineating eloquent cortex in extraoperative mapping. However, ECS is still coarse and inefficient in delineating regions of functional cortex and can be hampered by afterdischarges. Given these constraints, an adjunct approach to defining motor cortex is the use of electrocorticographic (ECoG) signal changes associated ...
متن کاملElectrocorticographic Frequency Alteration Mapping: a Clinical Technique
Received, May 25, 2006. Accepted, November 10, 2006. Creating transient lesions or inducing overt movements through the use of direct electrocortical stimulation (ECS), either extraor intraoperatively, has been an established practice in delineating eloquent cortex (3, 5, 26). This has been critical in minimizing the risk in neurological surgeries that involve seizure focus, tumor, or vascular ...
متن کاملPassive real-time identification of speech and motor cortex during an awake craniotomy.
Precise localization of eloquent cortex is a clinical necessity prior to surgical resections adjacent to speech or motor cortex. In the intraoperative setting, this traditionally requires inducing temporary lesions by direct electrocortical stimulation (DECS). In an attempt to increase efficiency and potentially reduce the amount of necessary stimulation, we used a passive mapping procedure in ...
متن کامل[Anesthetic considerations for awake craniotomy: case report].
BACKGROUND AND OBJECTIVES The conscious patient cooperation during neurological procedures has become necessary for the delimitation of areas to be managed by a neurosurgeon, with better results in the treatment of tumor lesions, vascular or epileptic foci, and lesser sequelae. The need for perioperative awareness (responsiveness to commands) challenges anesthesiologists to further ensure patie...
متن کاملAnesthesia for awake craniotomy: case report.
BACKGROUND AND OBJECTIVES Some intracranial procedures are achievable with patients awake, however, there are challenges ranging from patient compliance to homeostasis. The aim of this study is to present a case of intracranial surgery for removal of a tumor in the left parietal lobe with the patient awake during the procedure. CASE REPORT After patient selection and psychological preparation...
