[Impeded recirculation after removal of circulatory obstructions by the structural viscosity of the blood]

Poststenotically developing aggregates of erythrocytes aggravate the recirculation of the blood vessel after removal of the obstruction. This is shown in model experiments in which blood vessels are observed vital-microscopically for a longer time. Place and extension of the diminished postischaemic blood circulation are variable and depend on the different size, the deformability, the adhesivity and localisation of the aggregates or erythrocytes.
