title: Impaired red cell deformability in peripheral vascular disease.
abstract: By means of a recently developed technique, red-cell deformability was measured in 44 patients with peripheral vascular disease and in 44 age and sex matched normal control subjects. 28 patients had intermittent claudication and 16 rest pain or gangrene. The ability of the red cells to deform was significantly reduced in patients and significantly less in patients with rest pain or gangrene than in those who only had intermittent claudication. A reduction in red-cell deformability by retarding blood-flow through the microcirculation may be an important factor in states of peripheral vascular insufficiency.
