Intracranial Pressure vs Intracranial Pressure-Wave Amplitude

Arterial blood pressure vs intracranial pressure in normal pressure hydrocephalus.

OBJECTIVE To characterize the association between arterial blood pressure (ABP) and intracranial pressure (ICP) in idiopathic normal pressure hydrocephalus (iNPH) patients, and its impact on outcome of shunt surgery. MATERIALS AND METHODS We analyzed all 35 iNPH patients whose ABP and ICP were recorded simultaneously during 6 years (2002-2007). The static and pulsatile pressures were averaged...

Intracranial pressure monitoring.

Recent studies have demonstrated that bedside cranial burr hole and insertion of intraparenchymal catheters for intracranial pressure monitoring performed by intensive care physicians is a safe procedure, with a complication rate comparable to other series published by neurosurgeons. The overall morbidity rate is comparable to, or even lower than, that caused by central vein catheterization. Th...

Raised intracranial pressure.

Raised intracranial pressure (ICP) is a common problem in neurosurgical and neurological practice. It can arise as a consequence of intracranial mass lesions, disorders of cerebrospinal fluid (CSF) circulation, and more diffuse intracranial pathological processes. Its development may be acute or chronic. There are well established methods for the measurement, continuous monitoring, and treatmen...

Intracranial Pressure Sensor

Increased Intracranial Pressure

After closure of the cranial fontanelles and sutures by 2 to 3 years of age, the skull is a rigid container of fixed volume. The intracranial contents constitute the brain bulk (80%), blood volume (10%), and cerebrospinal fluid (CSF) (10%). According to the Monro-Kellie doctrine, intracranial volume is equal to the volume of the brain bulk, blood, CSF, and other mass lesions. Therefore, an incr...
