Critical limb ischaemia in patients over 80 years of age: options in a district general hospital.

A total of 114 reconstructions were performed in 82 octogenarian patients and the results compared with those of 33 patients who had primary amputation. The operative mortality rate was higher after amputation (45 versus 11 per cent) and the mean survival less (25 versus 34 months). Quality of life assessment using a Rosser scale suggested that, although there was no improvement in the 38 per cent with a failed reconstruction, there was a significant improvement in the 62 per cent whose reconstruction remained patent. There was minimal improvement in quality of life after primary amputation and this was due to relief of pain. Costs (including the costs of revisions and community costs) were assessed in detail. Although the mean total operative costs of reconstruction were higher than those of amputation (10,222 pounds versus 6475 pounds) this was more than offset by the high community costs of amputation. The total cost of reconstruction was 13,546 pounds, compared with 33,095 pounds for amputation. Following reconstruction 66 per cent of those patients independent before critical limb ischaemia occurred were able to return to their own home; only 33 per cent of amputees were able to do so.
