To study the long-term survival patterns of patients subjected to surgery for lower limb ischaemia.
A retrospective clinical study.
University Hospital.
A series of 1411 patients older than 50 years operated on for all stages of lower limb ischaemia.
Observed and expected long-term survival rates were calculated. Relative survival, defined as the ratio of the observed to the expected survival rates, was studied for age influence.
The observed 10 year survival rate of 26% was significantly lower than the expected of 49%. Although women were 8 years older than men at the time of the operation they had similar long-term survival and relative survival. An inverse proportionality was found between the patient's age at the time of the operation and relative survival. The young patients experienced a 10 year mortality rate three to four times the expected, while the older had a mortality that was elevated 25-50% from the expected.
Patients operated on for lower limb ischaemia experience a significantly lower long-term survival than that of a demographically matched population. This relative survival is significantly influenced by the patient's age at the time of the operation.
研究接受下肢缺血手术患者的长期生存模式。
一项回顾性临床研究。
大学医院。
一系列1411例年龄超过50岁、因下肢缺血各阶段接受手术的患者。
计算观察到的和预期的长期生存率。研究相对生存率（定义为观察到的生存率与预期生存率之比）受年龄的影响。
观察到的10年生存率为26%，显著低于预期的49%。尽管女性在手术时比男性大8岁，但她们的长期生存率和相对生存率相似。发现患者手术时的年龄与相对生存率之间呈反比关系。年轻患者的10年死亡率是预期的三到四倍，而老年患者的死亡率比预期高25%-50%。
接受下肢缺血手术的患者长期生存率明显低于人口统计学匹配人群。这种相对生存率受患者手术时年龄的显著影响。
