title: [The relation of flow velocity in the carotid vessels to age].
abstract: Using continual Doppler sonography, the authors measured the highest systolic blood flow rate in the extracranial carotid bloodstream in 3 groups of non-cardiac patients of an average age of 22, 76 and 93 years. In each group, the arteria carotis communis showed, with increasing age, a decrease in the highest systolic rate: 0.692 +/- 0.084 - 0.414 +/- 0.073 - 0.297 +/- 0.031 m/s (p less than 0.01 in all the three groups). Equally, a decrease in the highest systolic rate was found in the arteria carotis interna: 0.506 +/- 0.071 - 0.298 +/- 0.064 - 0.211 +/- 0.10 m/s (p less than 0.01 in all 3 groups). The paper shows a statistically significant decrease in the systolic blood rate in the carotid bloodstream related to aging (p less than 0.01) and discusses causes of this phenomenon.
