The paper deals experimentally with the influence of the blood flow on the long-term fate of venous grafts in the arterial circulation. Based on the results of experiments, and applying the laws of haemodynamics, the paper provides evidence that the blood flow has a decisive influence on the behavior of the implanted vein. Veins with a mean flow of 364.5 ml/min, dilate by 70% while the external diameter of veins with a mean flow of 65.4 ml/min. remain without major changes. This difference in the behaviour is statistically significant at the 1% level. From the results ensues that the vein is suited for reconstructions where a blood flow of 50--200 ml/min. may be expected.
本文通过实验研究了血流对动脉循环中静脉移植物长期转归的影响。基于实验结果并应用血液动力学定律，本文证明血流对植入静脉的行为具有决定性影响。平均血流量为364.5毫升/分钟的静脉扩张了70%，而平均血流量为65.4毫升/分钟的静脉外径基本没有变化。这种行为差异在1%的水平上具有统计学意义。从结果可以推断，该静脉适用于预期血流量为50-200毫升/分钟的重建手术。
