| ischemic mitral regurgitation | A regurgitation of the mitral valve caused by ischemic heart disease. (05 Mar 2000) |

| ischemic muscular atrophy | See: Volkmann's contracture. (05 Mar 2000) |
| ischemic necrosis | Necrosis caused by hypoxia resulting from local deprivation of blood supply, as by infarction. (05 Mar 2000) |
| ischemic neuropathy | Neuropathy resulting from acute or chronic ischemia of the involved nerves. (05 Mar 2000) |
| ischemic optic neuropathy | Optic nerve neuropathy secondary to hypoperfusion of the low pressure posterior ciliary arteries supplying the optic nerve head (nonarteritic) or to temporal arteritis (arteritic). (05 Mar 2000) |
| ischemic preconditioning | A technique in which tissue is rendered resistant to the deleterious effects of prolonged ischemia and reperfusion by prior exposure to brief, repeated periods of vascular occlusion. (am j physiol 1995 may;268(5 pt 2):h2063-7, abstract) (12 Dec 1998) |
| ischemic preconditioning, myocardial | Exposure of myocardial tissue to brief, repeated periods of vascular occlusion in order to render the myocardium resistant to the deleterious effects of ischemia or reperfusion. The period of pre-exposure and the number of times the tissue is exposed to ischemia and reperfusion vary, the average being 3 to 5 minutes. (12 Dec 1998) |
| optic neuropathy, ischemic | A severely blinding disease resulting from loss of the arterial blood supply to the optic nerve as a result of occlusive disorders of the nutrient arteries. Optic neuropathy is divided into anterior, which causes a pale oedema of the optic disk, and posterior, in which the optic disk is not swollen and the abnormality occurs between the globe and the optic chiasm. Ischemic anterior optic neuropathy usually causes a loss of vision that may be sudden or occur over several days; ischemic posterior optic neuropathy is uncommon and the diagnosis depends largely upon exclusion of other causes, chiefly stroke and brain tumour. (12 Dec 1998) |
| transient ischemic attack | A sudden focal loss of neurological function with complete recovery usually within 24 hours; caused by a brief period of inadequate perfusion in a portion of the territory of the carotid or vertebral basilar arteries. (05 Mar 2000) |
| Arantius' ventricle | Inferior part of the rhomboid fossa; the narrow lower end of the fourth ventricle between the two clavae. Synonym: Arantius' ventricle. Origin: L. Writing pen (05 Mar 2000) |
| bulb of lateral ventricle | A rounded elevation in the dorsal part of the medial wall of the posterior horn of the lateral ventricle, produced by the major forceps. (05 Mar 2000) |
| bulb of posterior horn of lateral ventricle of brain | Bulb of posterior horn of lateral ventricle of the brain; a curved elevation on the inner wall of the posterior horn produced by the fibres of the forceps major of the corpus callosum as they bend backward into the occipital lobe. Synonym: bulb of posterior horn of lateral ventricle of brain. (05 Mar 2000) |
| vein of lateral recess of fourth ventricle | A small vein originating in the cerebellar tonsil, coursing by the lateral recess of the fourth ventricle on its way to terminate in the petrosal vein. Synonym: vein of lateral recess of fourth ventricle. (05 Mar 2000) |
| ventricle | <anatomy> The paired (right and left) more muscular chambers of the heart that pump blood into the pulmonary (right ventricle) and systemic (left ventricle) circulation. (27 Sep 1997) |
| 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) |
