Índice Pressão Tornozelo Braço: Implicação no Tempo de Cicatrização da Úlcera de Perna

Background: Venous leg ulcers (VLUs) are the most common chronic type of leg ulcer. The ankle-brachial index (ABI) is a simple, non-invasive method that can be used to rule out arterial disease, ensuring safe care. Objective: To determine whether the ABI predicts healing time in individuals with VLUs. Methodology: A quantitative, descriptive-correlational, cross-sectional, and retrospective study was conducted with a non-randomized convenience sample collected from two complex wound treatment units. Documentary data was collected using a questionnaire between January 2021 and December 2022. Results: VLUs were the most prevalent (74.5%). The mean ABI value was 1.02. The median healing time for VLUs was 67 days. There was a negative and moderate correlation between healing time and ABI (ρ = -0.34). Conclusion: The lower the ABI value, the longer the required healing time. Due to the moderate correlation, other clinical variables must be considered when planning nursing interventions.
