: The Course of Experimental Cerebral Infarction —The Development of Increased Intracranial Pressure • In cats being subjected to surgical occlusion of the middle cerebral artery, regional oxygen availability (O2a) was monitored continuously from four open-tip platinum electrodes in the ischemic hemisphere and one in the control hemisphere. Extradural pressure over the convexity of the ischemic...

tt is easy to comprehend that spinal cord tumours located in the cervical region or the cervico-cranial junction can produce symptoms of increased intra-cranial pressure by mechanical obstruction of the spinal fluid pathway. It is more difficult to rationalize , however, the occurrence of these symptoms with tumours in the thoracic and lumbar spine. The rarity of this incidence is supported by ...

Functional and molecular changes associated with pathophysiological conditions are relatively easily detected based on tissue samples collected from patients. Population specific cellular responses to disease might remain undiscovered in samples taken from organs formed by a multitude of cell types. This is particularly apparent in the human cerebral cortex composed of a yet undefined number of...

I ncreased pressure within the cranial cavity is a common and important problem in the care of patients with serious injuries and diseases of the central nervous system. Elevated intracranial pressure (ICP) is most commonly associated with severe head injury; some degree of increased ICP was found in 80 percent of all patients with a major head injury and in over one half of these patients the ...

many patients fear about neurological disorders because of mistrust to their judgments. reality is that neurological system is one of the simplest systems, but unfortunately we discuss about it in a form that induce fear to people. suppose that an old person hospitalized for cerebro-vascular accident (cva) and increased intracranial pressure (icp). results of your assessment can increase patien...

Intracranial hypertension (ICH) was systematized in four categories according to its aetiology and pathogenic mechanisms: parenchymatous ICH with an intrinsic cerebral cause; vascular ICH, which has its actiology in disorders of cerebral blood circulation: ICH caused by disorders of cerebro-spinal fluid dynamics and idiopathic ICH. The increase of intracranial pressure is the first to happen an...

Intracranial hypotension increases cerebral blood flow. In dogs the average increase in cortical blood flow was 30 ml./100 g/min (47%) when the intracranial pressure was lowered acutely from 100 to 40 mm CSF. Permanent intracranial hypotension was established in seven demented patients using a ventriculoatrial shunt. The mean post shunt pressure was 50 mm CSF. In this group, the cerebral vascul...

BACKGROUND The relationship between changes in intracranial pressure and incidence of subclinical seizures in patients requiring neurological intensive care is not fully understood. The aim of this study was to investigate if acute increases in intracranial pressure were accompanied by subclinical seizures. METHODS We prospectively studied 17 intensive care patients (11 male, aged 3-66 yr) wh...

Hypoperfusion injury related to blood pressure decrease in acute hypertensive intracerebral hemorrhage continues to be a controversial topic. Aggressive treatment is provided with the intent to stop the ongoing bleeding. However, there may be additional factors, including autoregulation and increased intracranial pressure, that may limit this approach. We present here a case of acute hypertensi...
