| decompression, surgical | A surgical operation for the relief of pressure in a body compartment or on a body part. (12 Dec 1998) |
|---|---|
| internal decompression | Removal of intracranial tissue, usually tumour or brain tissue. To relieve pressure. (05 Mar 2000) |
| optic nerve sheath decompression | A venting of the optic nerve sheath into the retrobulbar space, by slitting or by fenestrating the sheath. See: optic nerve sheath fenestration. (05 Mar 2000) |
| orbital decompression | Removal of a portion of the bony orbit, usually superior (Naffziger operation), lateral (Kronlein operation), or inferior (Ogura operation). (05 Mar 2000) |
| trigeminal decompression | Decompression of the trigeminal nerve root. (05 Mar 2000) |
| explosive decompression | Sudden severe expansion of gases due to a reduction in ambient pressure. Synonym: explosive decompression. (05 Mar 2000) |
| anterior cerebral artery | <anatomy, artery> One of the two terminal branches (with middle cerebral artery) of the internal carotid; it passes anterior, loops around the genu of the corpus callosum then posteriorly in the interhemispheric fissure along with its fellow of the opposite side, the two being joined by the anterior communicating artery; for descriptive purposes it is divided into two parts: the precommunical part (A2 segment of clinical terminology), supplying branches to the thalamus and corpus striatum, and the postcommunical part, (A2) or pericallosal artery, supplying branches to the cortex of the medial parts of the frontal and parietal lobes. Synonym: arteria cerebri anterior. (05 Mar 2000) |
| anterior cerebral vein | <anatomy, vein> A small vein that parallels the anterior cerebral artery and drains into the basal vein. Synonym: vena cerebri anterior. (05 Mar 2000) |
| arteries of cerebral haemorrhage | Numerous small branches from the sphenoidal part of the middle cerebral arteries supplying the lateral and anterior parts of the corpus striatum. Synonym: arteriae centrales anterolaterales, arteriae thalamostriatae anterolaterales, anterolateral central arteries, anterolateral striate arteries, anterolateral thalamostriate arteries, arteries of cerebral haemorrhage, lenticulostriate arteries. (05 Mar 2000) |
| ganglionic layer of cerebral cortex | Layer 5 of the cortex cerebri. (05 Mar 2000) |
| malaria, cerebral | A condition that is most commonly seen as a severe complication of malaria, falciparum mainly involving the brain. It has also been reported to occur as a result of infection with other plasmodium species. This disease is often fatal and presents as disturbances in consciousness ranging from somnolence to coma, major motor seizures, and organic psychosis. The onset may be gradual or sudden following a convulsion. (12 Dec 1998) |
| ventricle of cerebral hemisphere | A cavity shaped somewhat like a horseshoe in conformity with the general shape of the hemisphere; each lateral ventricle communicates with the third ventricle through the interventricular foramen of Monro, and expands from there forward into the frontal lobe as the anterior horn as well as caudally over the thalamus as the central part or cella media which, behind the thalamus, curves ventrally and laterally, then forward into the temporal lobe as the inferior horn; from the apex of the curve a variably sized posterior horn extends back into the white matter of the occipital lobe. The large choroid plexus of the lateral ventricle invades the cella media and the inferior horn (but not the anterior and posterior horn) from the medial side. Synonym: ventriculus lateralis, ventricle of cerebral hemisphere. (05 Mar 2000) |
| paroxysmal cerebral dysrhythmia | A diffusely abnormal electroencephalogram often seen with epilepsy. (05 Mar 2000) |
| medial cerebral surface | It faces, above as well as anterior and posterior to the corpus callosum, the falx cerebri; below it are the mesencephalon and the dura-covered medial wall of the middle cranial fossa. Synonym: facies medialis cerebri, medial cerebral surface. (05 Mar 2000) |
