title: Influence of age on survival of patients treated surgically for lower limb ischemia.
abstract: BACKGROUND
  Investigators in Norway reported long-term survival experience in patients treated surgically for lower leg occlusive atherosclerotic disease over the period 1974 to 1993.
  
  
  RESULTS
  Ten-year survival data were provided for seven age groups. Average annual mortality ratios decreased with age at time of surgery from a high of 460% in the 50-54 year-old age group to a low of 212% in patients > 80 years of age.
  
  
  CONCLUSIONS
  Excess mortality was related to age. This same mortality pattern is observed with most impairments, i.e., mortality ratios are usually highest at younger ages, intermediate in the middle-aged people, and lower in the very elderly.
