Outcomes of Acute Limb Ischemia at a Large Public Hospital in Brazil: Insights before, during and after the COVID-19 Pandemic.

Background: This study compared outcomes of patients with acute limb ischemia (ALI) before, during, and after the COVID-19 pandemic, hypothesizing that poor outcomes observed during the pandemic have not yet been resolved.

Methods: This retrospective, observational, single-center study analyzed ALI patients from 2019 to 2023.

Results: Over 5 years, 298 patients underwent surgery for ALI at our hospital: 35 had COVID-19 (COVID group), 132 tested negative (non-COVID group), 71 were treated before the pandemic (pre-COVID group), and 60 after (post-COVID group).
