Monitoring in carotid endarterectomy.

Handb Clin Neurol 2022 ;186:355-374

Department of Neurosurgery, Mount Sinai Hospital, New York, NY, United States.

Cerebral ischemia during carotid endarterectomy occurs via several mechanisms: inadequate collateral blood flow during carotid cross-clamping, thromboembolism due to carotid manipulation, and/or rethrombosis at the surgical site. Perioperative strokes increase not only the morbidity of endarterectomy but also its short- and long-term mortality. However, while several predictors of cerebral ischemia have been identified, precise individual risk is hard to assess. Read More

Monitoring surgery around the cranial nerves.

Handb Clin Neurol 2022 ;186:319-351

Department of Neurology, Montefiore Medical Center and Albert Einstein College of Medicine, Bronx, NY, United States.

Intraoperative neurophysiologic monitoring (IONM) of cranial nerve (CN) function is an essential component in multimodality monitoring of surgical procedures where CNs are at risk for injury. In most cases, IONM consists of localizing and mapping CNs and their pathways, and monitoring of CN motor function during surgery. However, CN VIII, which has no motor function, and is at risk for injury in many surgical procedures, can be easily and accurately monitored using brainstem auditory evoked potentials. Read More

Intraoperative neurophysiology in intramedullary spinal cord tumor surgery.

Handb Clin Neurol 2022 ;186:229-244

Department of Neurosurgery, University Hospital Dubrava, Zagreb, Croatia; Albert Einstein College of Medicine, New York, NY, United States.

Intramedullary spinal cord tumor (ISCT) surgery is challenged by a significant risk of neurological injury. Indeed, while most ISCT patients arrive to surgery in good neurological condition due to early diagnosis, many experience some degree of postoperative sensorimotor deficit. Thus, intraoperative neuromonitoring (IONM) is invaluable for providing functional information that helps neurosurgeons tailor the surgical strategy to maximize resection while minimizing morbidity.

Mapping and monitoring of brainstem surgery.

Handb Clin Neurol 2022 ;186:151-161

Department of Neurosurgery, University Hospital Dubrava, Zagreb, Croatia; Albert Einstein College of Medicine, New York, NY, United States.

The surgical morbidity of brainstem lesions is higher than in other areas of the central nervous system because the compact brainstem is highly concentrated with neural structures that are often distorted or even unrecognizable under microscopic view. Intraoperative neurophysiologic mapping helps identify critical neural structures to avoid damaging them. With the trans-fourth ventricular floor approach, identifying the facial colliculi and vagal and hypoglossal triangles enables incising and approaching the brainstem through the safe entry zones, the suprafacial or infrafacial triangle, with minimal injury.

Intraoperative mapping and monitoring during brain tumor surgeries.

Handb Clin Neurol 2022 ;186:133-149

Department of Oncology and Hemato-Oncology, Neurosurgical Oncology Unit, Università degli Studi di Milano, Milan, Italy.

Many different methodologies and paradigms are available to guide surgery of supratentorial tumors with the aim to preserve quality of life of the patients and to increase the extent of tumor resection. Neurophysiologic monitoring techniques (such as different evoked potentials) may help to continuously assess functional integrity of the observed systems and warn about vascular injury. For neurophysiologic mapping methods, the focus is not only to preserve cortical sites, but also to prevent injury to subcortical pathways. Read More

Neurophysiology during movement disorder surgery.

Handb Clin Neurol 2022 ;186:123-132

Department of Neuroscience, University of California Riverside, Riverside, CA, United States.

During stereotactic procedures for treating medically refractory movement disorders, intraoperative neurophysiology shifts its focus from simply monitoring the effects of surgery to an integral part of the surgical procedure. The small size, poor visualization, and physiologic nature of these deep brain targets compel the surgeon to rely on some form of physiologic for confirmation of proper anatomic targeting. Even given the newer reliance on imaging and asleep deep brain stimulator electrode placement, it is still a physiologic target and thus some form of intraoperative physiology is necessary.
