Abstract

Objective: We sought to determine the benefit of performing multiple tibial artery revascularization compared with single vessel revascularization for patients with chronic limb-threatening ischemia (CLTI). Methods: We performed a single-center, retrospective cohort study of all patients with CLTI treated with below-the-knee endovascular intervention from 2012 to 2019. Group 1 included patients who had undergone single tibial artery revascularization. Group 2 included patients who had undergone multiple (two or more) tibial artery revascularization. More proximal disease, if present, was treated, in addition to the tibial disease. The primary endpoint was freedom from amputation. The secondary endpoints included the reintervention rates and all-cause mortality. Results: A total of 527 limbs in 470 patients with CLTI (nonhealing ulcers, 62%; gangrene, 33%; and ischemic rest pain, 5%) were included in the present study. Of the 527 limbs, 245 (46%) had undergone single vessel revascularization and 282 (54%) had undergone multiple vessel revascularization. The mean follow-up was 19 ± 18 months. No difference was found in freedom from amputation between the two groups (68% vs 63%; P = .109). On multivariable analysis, the factors associated with amputation included dialysis (odds ratio [OR], 1.68; 95% confidence interval [CI], 1.16-2.45), dyslipidemia (OR, 1.37; 95% CI, 0.96-1.94), and gangrene (OR, 2.08; 95% CI, 1.50-2.98). No differences were found in the reintervention rates between the two groups (21.2% vs 16.7%; P = .13). The overall survival rate was 73% in both study groups. Conclusions: The results from the present large, single-center study have demonstrated that multiple below-the-knee vessel revascularization is not associated with improved limb salvage compared with single vessel revascularization.
