In the presence of multiple tandem arteriosclerotic stenoses of the distal aorta, iliac, and lower extremity arteries, it may be difficult to ascertain which lesions are clinically and surgically important. Usually the history, physical examination, and arteriogram will resolve this issue. However, a recent report has stated that the rapid transit time of isotope from the distal aorta to the femoral arteries may be helpful. The relevance of this technique in surgical candidates with different clinical stages of vascular disease has yet to be demonstrated. We compared the use of this technique in surgical candidates with their clinical state and assessment of vascular disease by standard angiographic and directional transcutaneous Doppler techniques. Only modest benefit from the isotope transit was found, particularly when compared with the patient's clinical status of asymptomatic, claudicating, or limb salvage categories. We conclude that isotope transit times as currently measured are not as clinically important as previously reported. With further development, some trends may prove to be useful.
在存在远端主动脉、髂动脉和下肢动脉多发串联性动脉硬化狭窄的情况下，可能难以确定哪些病变在临床和手术方面具有重要意义。通常，病史、体格检查和动脉造影将解决这个问题。然而，最近一份报告指出，同位素从远端主动脉到股动脉的快速通过时间可能会有所帮助。这项技术在不同临床阶段血管疾病手术候选者中的相关性尚未得到证实。我们将这项技术在手术候选者中的应用与他们的临床状态以及通过标准血管造影和定向经皮多普勒技术对血管疾病的评估进行了比较。发现同位素通过时间仅有适度益处，特别是与患者无症状、间歇性跛行或肢体挽救类别的临床状态相比时。我们得出结论，目前所测量的同位素通过时间在临床上并不像先前报道的那样重要。随着进一步发展，一些趋势可能会被证明是有用的。
