Therapeutic Results of Critical Leg Ischemia in Aged Patients with Arteriosclerosis Obliterans / 日本心臓血管外科学会雑誌

ABSTRACT

We treated 261 arteriosclerosis obliterans cases with critical leg ischemia since 1976. Those patients aged 75 years and older were designated as the elderly group and were compared with those under 75 years of age. Among the elderly patients with critical leg ischemia, the percentages of women and Fontaine scale IV cases were higher. The condition of those who had to undergo an initial major amputation was often complicated by cerebrovascular diseases, resulting in a higher early death rate after operation. Therefore, the necessity of early diagnosis and immediate treatment must be emphasized. There were no differences in patency and limb salvage rates between the two groups. In cases of arterial reconstruction however, graft occlusion in the elderly group immediately after operation was frequently observed. It is important to include drug therapy in follow-up to prevent occlusion of the graft following surgery in elderly patients.
