What is an intracranial process?
Intracranial: Within the cranium, the bony dome that houses and protects the brain. An intracranial hemorrhage is bleeding within the cranium due, for example, to a stroke or leakage of blood from an aneurysm in the brain.
What is the definition of intracranial?
: existing or occurring within the cranium also : affecting or involving intracranial structures.
What does brain swelling feel like?
Symptoms of brain swelling include headache, dizziness, nausea, numbness or weakness, loss of coordination or balance, loss of the ability to see or speak, seizures, lethargy, memory loss, incontinence, or altered level of consciousness.
What is intracranial extension?
Tumors with intracranial extension and/or involvement of the cranial nerves, infratemporal fossa, hypopharynx or orbit have been defined as Stage T4 by the AJCC (9); and intracranial tumor involvement has been considered to be a significant barrier to achieving successful treatment.
What happens if intracranial hypertension is not treated?
Intracranial hypertension means that the pressure of the fluid that surrounds the brain (cerebrospinal fluid or CSF) is too high. Elevated CSF pressure can cause two problems, severe headache and visual loss. If the elevated CSF pressure remains untreated, permanent visual loss or blindness may result.
How is intracranial pressure monitoring ( ICP ) performed?
Intracranial pressure (ICP) monitoring uses a device placed inside the head. The monitor senses the pressure inside the skull and sends measurements to a recording device. How the Test is Performed There are three ways to monitor ICP.
Why is intracranial monitoring important for brain surgery?
Using data from intracranial monitoring helps brain surgeons more precisely locate and remove brain tissue that is causing seizures, while preserving essential brain functions such as speech and movement. Why might my doctor recommend intracranial monitoring?
How is intracranial monitoring used to diagnose epilepsy?
Neurosurgeons use these data in planning a patient’s epilepsy surgery. For intracranial monitoring, the surgeon places electrodes inside the skull to record electrical activity from the brain.
How is an intracranial pressure catheter inserted?
The catheter may be hard to get into place when the intracranial pressure is high. SUBDURAL SCREW (BOLT) This method is used if monitoring needs to be done right away. A hollow screw is inserted through a hole drilled in the skull. It is placed through the membrane that protects the brain and spinal cord (dura mater).
