This study states that The optimal techniques to manage acute limb ischemia (ALI) remain unclear. Previous reports have suggested that the decreased morbidity and mortality of endovascular approaches are mitigated by the limited technical success rates relative to open or hybrid approaches for ALI. However, these data failed to include newer technologies that might improve the technical success rates. We, therefore, sought to describe the current outcomes for an endovascular-first approach to ALI.

We performed a single-center, single-arm, retrospective cohort study of consecutive patients with ALI from 2015 to 2018. Technical success, limb salvage, survival, patency, and length of stay were quantified using Kaplan-Meier (KM) analysis. Cox regression analysis was used to identify the predictors of amputation-free survival. The current endovascular approaches to ALI have high technical success rates. Survival, limb salvage, perioperative complications, and length of stay were similar to those from previous reports of historical open cohorts. Further prospective, appropriately powered, multicenter cohort studies are warranted to evaluate the efficacy of endovascular vs open approaches to ALI.
