The aim of this systematic review and meta-analysis was to assess the clinical outcomes after revascularisation in octogenarians with chronic limb threatening ischaemia (CLTI).

This was a systematic review and meta-analysis, in which the Medline, Embase, and Cochrane Library databases were searched systematically by two independent researchers. Meta-analyses were performed to analyse one year mortality, one year major amputation, and one year amputation free survival (AFS) after revascularisation. Pooled outcome estimates were reported as percentages and odds ratio (OR) with 95% confidence intervals (CI). In addition, sensitivity and subgroup analyses were performed and the quality of evidence was determined according to the GRADE system. No significant difference in mortality rate was found between primary amputation and revascularisation in octogenarians (OR 0.70, 95% CI 0.24–2.03; GRADE: “very low”). In octogenarians with CLTI, a substantial one year mortality rate of 32% was found after revascularisation. The amputation rates were comparable between both age groups. However, only low quality evidence could be obtained supporting the results of this meta-analysis because only observational studies were available for inclusion.
