A method for mean flow velocity measurement using digital subtraction angiography (DSA) was evaluated, along with the results of phantom and animal experiments. The validity of its clinical use was studied by applying this technique in the arteries and bypass grafts in patients with arterial occlusive disease. Mean flow velocity was reliably determined by this method, but it could not be used as a determinant of arterial occlusive disease, because of a considerable overlapping between limbs with and without significant arterial lesions. A low value of mean flow velocity was not itself a reliable prognostic indicator of bypass failure. However, measurement of mean flow velocity was valuable in detecting functional abnormalities of the graft.
评估了一种使用数字减影血管造影（DSA）测量平均流速的方法，以及模型和动物实验的结果。通过将该技术应用于动脉闭塞性疾病患者的动脉和旁路移植物，研究了其临床应用的有效性。该方法能够可靠地测定平均流速，但由于有显著动脉病变和无显著动脉病变的肢体之间存在相当大的重叠，因此不能将其用作动脉闭塞性疾病的决定因素。平均流速低值本身并不是旁路失败的可靠预后指标。然而，平均流速的测量对于检测移植物的功能异常具有重要价值。
