| ischaemia | <physiology> A low oxygen state usually due to obstruction of the arterial blood supply or inadequate blood flow leading to hypoxia in the tissue. Origin: Gr. Haima = blood (13 Nov 1997) |
| ischaemic | Affected by ischaemia. (27 Sep 1997) |
| ischaemic bowel disease | <surgery> A disorder which results from the inadequate flow of oxygenated blood to the intestines. Symptoms include crampy abdominal pain after eating. More common in those with a history of atherosclerosis and-or diabetes. (15 Oct 1997) |
| ischemia | <physiology> A low oxygen state usually due to obstruction of the arterial blood supply or inadequate blood flow leading to hypoxia in the tissue. Origin: Gr. Haima = blood (13 Nov 1997) |
| ischemia retinae | Diminished blood supply in the retina due to failure of the arterial circulation; it may occur as a result of arterial embolism or spasm; poisoning, as by quinine; or exsanguination from recurring profuse haemorrhages (e.g., in parturition, gastric and duodenal ulcers, and pulmonary tuberculosis); bilateral transitory or permanent blindness may result.

| ischemia-modifying factors | Various factors that play a role in determining the extent of necrosis with cerebral stroke; these include blood viscosity and osmolality, the blood pressure, and the anatomy of the neck and intracranial arteries. (05 Mar 2000) |
| ischemic | Affected by ischaemia. (27 Sep 1997) |
| ischemic colitis | <radiology> Precipitating factors: volvulus, carcinoma, cardiovascular disease, history of aortoiliac reconstruction (2%) with ligation of IMA, abrupt onset of lower abdominal pain and rectal bleeding, location: splenic flexure (80%) and rectosigmoid (watershed areas), BE: single contrast prefered (lesions may become effaced with double contrast), serrated mucosa; pseudopolyposis; transverse ridging; thumbprinting on mesenteric side; deep ulcers, CT: thickening of wall; irregular lumen (thumbrinting), curvilinear collection of intramural gas, portal and mesenteric venous air, blood clot in superior mesenteric artery / superior mesenteric vein, Angio (similar to inflammatory disease): normal / slightly attenuated arterial supply, mild acceleration of arteriovenous transit time (12 Dec 1998) |
| ischemic contracture of the left ventricle | Irreversible contraction of the left ventricle of the heart as a complication seen in the early period of cardiopulmonary bypass and now avoided by appropriate cardioplegic solutions. Synonym: myocardial rigor mortis, stone heart. (05 Mar 2000) |
