PURPOSE: To evaluate the safety and effectiveness of below-the-ankle (BTA) angioplasty and to assess whether additional BTA angioplasty after below-the-knee (BTK) angioplasty would improve clinical outcomes in patients with critical limb ischemia.

MATERIALS AND METHODS: Two authors independently performed the search, study selection, assessment of methodological quality, and data extraction for this systematic review and meta-analysis. MEDLINE, Embase, and the Cochrane Database of Systematic Reviews were searched. Articles were eligible if it was reported that BTA angioplasty was performed and if the articles were published in English and had the full text available. Methodological quality was assessed using the Methodological Index for Non-Randomized Studies (MINORS) score. The primary outcome was 12-month limb salvage rate. Secondary outcomes were 12-month amputation-free survival, technical success, complications, survival, and freedom from reintervention.

RESULTS: Ten articles met the inclusion criteria, reporting a total of 478 patients with BTA angioplasty performed in 524 legs. Three of the 10 included studies compared BTK angioplasty only to BTK angioplasty and additional BTA angioplasty. The pooled 12-month limb salvage rate was 92% (95% confidence interval [CI], 0.88-0.96). No statistically significant difference was found in limb salvage when additional BTA angioplasty was compared to BTK angioplasty only (odds ratio [OR], 1.23; 95% CI, 0.61-2.49). The pooled 12-month amputation-free survival was 78% (95% CI, 0.69-0.87). No statistically significant difference was found in amputation-free survival rate when additional BTA angioplasty was compared to BTK angioplasty only (OR, 1.58; 95% CI, 0.95-2.64). The methodological quality of the studies included was moderate, according to the MINORS score.

CONCLUSIONS: This systematic review and meta-analysis showed that additional BTA angioplasty is a safe and feasible procedure, with a 92% pooled proportion of limb salvage at 12 months.
