In many cases of digital gangrene, limited amputation to preserve the majority of the foot is possible. In the absence of invasive infection, forefoot perfusion pressure is the single most important factor in determining outcome of minor amputation. At ankle pressures of less than 35 mm. Hg, salvage of the foot appears to be futile. The presence or absence of diabetes mellitus has no noticeable effect on the result of amputation. Ankle systolic pressure measurement cannot supplant but should supplement clinical judgement in selecting surgical treatment for gangrene.
在许多数字坏疽病例中，进行有限截肢以保留足部的大部分是可行的。在没有侵袭性感染的情况下，前足灌注压是决定小截肢预后的唯一最重要因素。当踝部压力低于35毫米汞柱时，保足似乎是徒劳的。糖尿病的有无对截肢结果没有明显影响。在为坏疽选择手术治疗时，踝部收缩压测量不能取代但应补充临床判断。
