Late Mortality after Reconstructive Surgical Treatment of Atherosclerotic Occlusive Disease / 日本心臓血管外科学会雑誌

ABSTRACT

We reviewed the clinical course of 127 patients who underwent treatment for atherosclerotic disease between June 1993 and January 2001. There were 108 men and 19 women. The ages ranged from 49 to 88 years with a median age of 71.2 at the time of the first operation. Major risk factors included ischemic heart disease (21%) and diabetes mellitus (20%). Ninety-five percent of the patients were followed successfully and the follow-up period ranged from 0 to 90 months with a mean of 33 months. Two patients died perioperatively due to myocardial infarction. There were 29 late deaths. The overall actuarial survival rate was 69.7% at 5 years. The 5-year actuarial survival rate and the mean survival time for men and women were 71.6%, 66.1 months and 62.3%, 58.9 months. The 5-year late survival rate and the mean survival time for patients with and without ischemic heart disease were 57.0%, 57.4 months and 74.2%, 68.5 months. The differences were not statistically significant. The 5-year late survival rate and the mean survival time for patients with and without diabetes mellitus were 65.5%, 59.1 months and 70.9%, 67.4 months. The differences were not statistically significant. Amputation was performed in 7 patients, the actuarial survival rate at 1 year and the mean survival time were 42.9%, 7.1 months for patients with amputation, and 93.0%, 69.5 months without amputation (<i>p</i><0.01).
