sickle cell anaemia
See also: sickle-cell anaemia
- (pathology, Britain) A severe hereditary form of anaemia, mainly affecting people of African origin, in which mutated haemoglobin distorts red blood cells into a crescent shape, causing the cells to become stuck in capillaries. Downstream tissues are thus deprived of oxygen causing ischaemia and infarction.
