A study is made in this paper of the prognostic significance of a very low distal index (index 6), revealed by irrigraphy. On the basis of examination of 55 case histories, the patients were divided into two groups A and B as a function of the distal indices at the root of the limb. The amputation rate was very high in both groups, but the prognosis was better in group A where the situation could be improved by restorative surgery at a high level. Analysis of the surgical possibilities has indicated that restorative surgery at a high level is a promising procedure, especially in group A. Surgery at the femoro-popliteal level yielded less satisfactory results because of the often considerable degradation of the arterial bed further downstream. Sympathectomy appears to be a useful supplement to restorative surgery in appropriate cases. The concept of the reduced distal index is also valuable for detecting cases of arteritis which are still well compensated but are in danger of vascular failure (dangerous claudications).
本文对经血管造影显示的极低远端指数（指数6）的预后意义进行了研究。在检查55份病历的基础上，根据肢体根部的远端指数将患者分为A组和B组。两组的截肢率都很高，但A组的预后较好，在该组中，通过高水平的修复性手术，情况可以得到改善。对手术可能性的分析表明，高水平的修复性手术是一种很有前景的手术方法，尤其是在A组。由于下游动脉床常常严重退化，股腘水平的手术效果不太令人满意。在适当的病例中，交感神经切除术似乎是修复性手术的有益补充。远端指数降低的概念对于检测仍能良好代偿但有血管衰竭危险（危险性跛行）的动脉炎病例也很有价值。
