Neurology Intraoperative Monitoring (IOM) Service
Our mission is to provide an exceptional health care service to medical practitioners through professionalism, competence and responsiveness, resulting in superior patient outcomes.
Intraoperative Neurophysiologic Monitoring is a complex field with multiple domains which demand a broad range of faculty expertise. Research, teaching, and clinical activity encompass numerous specialty fields including: neurosurgery, orthopedic surgery, endovascular, pediatric surgery, cardiovascular surgery and neurourology surgery. The establishment of the Neurology IOM Department has permitted growth in all the domains of surgery and will provide teaching opportunities and research activity; which has enriched the quality of patient care, education and research.
What is the purpose of Intraoperative monitoring?
The IOM service provides a number of services to hospital physicians and their patients. IOM helps prevent dysfunction of the brain, cranial nerves, spinal cord and peripheral nerves during certain types of surgeries. IOM can also facilitate mapping of the cortex and spinal cord. IOM is suggested for cases in which surgical complications may cause a loss of neurological function, such as surgery of the spine, brain and nerve plexus. The use of neuromonitoring can assist in preventing or reversing loss of function. Suggested cases that use IOM include:
- surgery of the aortic arch, its branch vessels, including carotid artery surgery, when there is risk of cerebral ischemia
- resection of epileptogenic brain tissue or tumor
- Thoracic Aneurysm
- resection of brain tissue close to the primary motor cortex and requiring brain mapping distinguishing Sensory vs Motor Cortex
- protection of cranial nerves
- tumors that affect optic, trigeminal, facial, auditory nerves
- cavernous sinus tumors
- microvascular decompression of cranial nerves
- correction of scoliosis or deformity of spinal cord involving traction on the cord
- protection of spinal cord where work is performed in close proximity to cord as in the placement or removal of old hardware or where there have been numerous interventions.
- Myelopathic spinal cords
- spinal instrumentation requiring pedicle screws or distraction
- decompressive procedures on the spinal cord or cauda equina carried out for determined myelopathy or claudication where function of spinal cord or spinal nerves are at risk
- spinal cord tumors
- neuromas of peripheral nerves of brachial plexus, when there is risk to major sensory or motor nerves
- surgery or embolization for intracranial AV malformations
- surgery for arteriovenous malformation of spinal cord
- cerebral vascular aneurysms
- surgery for intractable movement disorders
- arteriography during which there is a test occlusion of the carotid artery
- circulatory arrest with hypothermia [does not include surgeries performed under circulatory bypass (e.g., CABG, ventricular aneurysms)]
- distal aortic procedures, where there is risk of ischemia to spinal cord
- leg lengthening procedures, where there is traction on sciatic nerve or other nerve trunks
- traumatic injury to the pelvis and sacrum
- surgery as a result of traumatic injury to spinal cord/brain
