	Intracranial pressure - Wikipedia, the free encyclopedia
		Intracranial pressure, or ICP, is the pressure of the brain, Cerebrospinal fluid (CSF), and the brain's blood supply within the intracranial space.
		The body’s response to a decrease in CPP is to raise blood pressure and dilate blood vessels in the brain.
		Intracranial pressure can be measured by means of a lumbar puncture or continuously with intracranial transducers (only used in neurosurgical intensive care).

		Intracranial tumors comprise more than 94 percent of primary intracranial and CNS tumors, and between 50 and 92 percent of primary intracranial and CNS tumors occur in the brain (Table 2).
		Among the malignant primary intracranial and CNS tumors, neuroepithelial (i.e., astrocytic) tumors represent 83 to 90 percent of the cases depending on the data source; lymphomas/hemopoietic tumors, 6 to 11 percent; tumors of the meninges, 1 to 2 percent; and tumors of cranial and spinal nerves, 0.2 percent (Table 8).
		For nonmalignant primary intracranial and CNS tumors, tumors of the meninges represent 48 to 59 percent of the cases; tumors of the sellar region (including pituitary tumors and craniopharyngiomas), 21 to 26 percent; tumors of cranial and spinal nerves, 11 to 20 percent; and neuroepithelial tumors, 4 to 5 percent (Table 9).

	Aggressive Management of Intracranial Dynamics (Site not responding. Last check: 2007-10-11)
		The intracranial injury may be related to head trauma, intracranial hemorrhage, tissue swelling, alterations in cerebral blood volume or blood flow, fluid shifts within the tissue and restrictions in flow, and production or absorption of cerebrospinal fluid.
		Intracranial compliance is of tremendous importance for the maintenance of intracranial dynamics.
		In a patient with an intracranial injury and chronic hypertension, it is vital to maintain the systemic blood pressure as close to the patient's baseline pressure as possible to preserve cerebral blood flow.

	INTRACRANIAL PRESSURE
		Normal intracranial pressure in adults is 8 to 18mm Hg and in babies the pressure is 10-20mm less when measured through a lumbar puncture.
		There is a rise with cardiac systole (due to distention of intracranial arteriolar tree which follows) and a slower change in pressure with respiration, falling with each inspiration and rising with expiration.
		Intracranial pressure is a result of at least 2 factors, the volume of the brain (about 1400ml in an adult) being constant.

	THE MERCK MANUAL, Sec. 14, Ch. 177, CNS Neoplasms
		An expanding intracranial lesion may be a granuloma, parasitic cyst, hemorrhage (intracerebral, extradural, or subdural), aneurysm, abscess, or neoplasm (metastatic or primary).
		Primary intracranial neoplasms may be classified by site (see Table 177-1) or by histologic type (eg, meningioma, primary CNS lymphoma, astrocytoma).
		Increased intracranial pressure may result from the space-occupying tumor mass, cerebral edema, obstructed flow of CSF (occurring early with 3rd ventricle or posterior fossa tumors), obstructed dural venous sinuses (especially by bony or extradural metastatic tumors), or obstructed CSF absorption mechanisms (eg, in leukemic or carcinomatous involvement of the meninges).

	Intracranial pressure monitoring (Site not responding. Last check: 2007-10-11)
		Intracranial pressure monitoring is usually done in cases of severe head injury or after surgeries in cases where a tumor or vascular lesion has been removed or repaired and the surgical team is concerned about brain swelling.
		Elevated intracranial pressure can be treated by draining CSF through the catheter, as well as by changing ventilator settings (for those patients who are in critical condition and on a respirator) or by the application of certain intravenous medications.
		Intracranial pressure monitoring is crucial in identifying the problem and allowing for immediate treatment.

	INTRACRANIAL PRESSURE (Site not responding. Last check: 2007-10-11)
		It is believed that intracranial pressure is a reflection of the atmospheric pressure which is conducted through the large neck vessels.
		Intracranial pressure needs to be measured over 24 to 48 hours to get a true representation.
		The most accurate method of measuring the intracranial pressure is by the use of electrodes with a sensor attached to its tip.

	INTRACRANIAL ANUERYSMS
		The majority of intracranial aneurysms (80 to 85 percent) are located in the anterior circulation, most commonly at the junction of the internal carotid artery and the posterior communicating artery, the anterior communicating-artery complex, or the trifurcation of the middle cerebral artery.
		Screening for asymptomatic intracranial aneurysms appears to be warranted, because aneurismal subarachnoid hemorrhage has a dismal prognosis, whereas the treatment of most asymptomatic intracranial aneurysms is associated with a fairly low rate of morbidity (less than 5 percent) and mortality (less than 2 percent).
		Clustering of intracranial aneurysms has been reported in several families with autosomal dominant polycystic kidney disease, and screening reveals asymptomatic aneurysms in 20 or 25 percent of the members of such families.

		Intracranial pressure is measured in millimeters of mercury (mm Hg).

		Although idiopathic intracranial hypertension, pseudotumor cerebri, and benign intracranial hypertension are synonymous with this diagnosis, the preferred term is idiopathic intracranial hypertension.
		The subsequent increase in the intracranial pressure is transmitted to the structures within the intracranial cavity, including the optic nerves.
		Although the intracranial pressure remains elevated in these patients postoperatively, the local filtering effect of the fenestration acts as a safety valve and eliminates the pressure from being transmitted to the optic nerve.

		The most devastating consequences of intracranial aneurysms, which often lead to severe disability or death, result from their rupture and bleeding into the space around the brain.
		Unruptured intracranial aneurysms can be detected by non-invasive measures, including magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA).
		A less invasive technique which does not require an operation, called endovascular therapy, uses microcatheters to deliver coils to the site of the enlarged blood vessel that occludes (closes up) the aneurysm from inside the blood vessel and may be more suitable for some patients.
