文摘

The aim was to report the midterm outcome for nonagenarians with critical limb ischemia (CLI) and to identify factors affecting survival or limb salvage rates.

Methods

Nonagenarians who underwent endovascular surgery (ES), open surgery (OS), or primary amputation (PA) for CLI between 2005 and 2014 were included. Cox regression model identified factors affecting survival and limb salvage.

Results

ES was performed in 116 patients (119 limbs), OS in 73 patients (73 limbs), and PA in 54 patients (57 limbs). Mean follow-up was 10.38 months. There was no difference in survival between ES, OS, and PA groups: survival rate was 51.2% at 1 year and 38.9% at 2 years after ES, 48.3% at 1 year and 39.6% at 2 years after OS, and 50.6% at 1 years and 40.8% at 2 years after PA (P = 0.58). There was no difference in limb salvage between ES and OS groups: limb salvage rate was 88.2% and 77.8% at 1 and 2 years after ES and 87.3% and 77.6% at 1 and 2 years after OS. Coronary artery disease (hazard ratio [HR] 1.54; confidence interval [CI] 1.04–1.08; P = 0.01) was risk factor for death. Fully dependent state was risk factor for death (HR 4.2; CI 3.55–4.87; P < 0.001) and major amputation (HR 5.3; CI 1.32–1.67; P < 0.001). In fully dependent patients, 1-year and 2-year survival rate was 28.9% and 20.6%, respectively, and 1-year and 2-year limb salvage rate was 61.2% and 44.5%, respectively.

Conclusions

With acceptable early and late mortality, limb salvage and maintenance of functional status and level of independent living, revascularization in nonagenarians is effective as long as the patient is not fully dependent.
