Prompt diagnosis and management are crucial to limit morbidity and mortality. Literature recommends a thorough vascular examination of at\u2010risk patients. Ankle brachial index (ABI) and arterial pressure index (API) are considered reliable screening tools for lower extremity vascular injury (LEVI) in the correct clinical scenario. Patients with an abnormal ABI\/API warrant diagnostic imaging with computed tomography angiography (CTA). However, recent international literature demonstrates a trend toward potential CTA overuse in the work up for LEVI, when the internationally recommended vascular injury work\u2010up guidelines are not followed correctly.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Aim<\/jats:title>\n                    <jats:p>To assess the reliability of ABI\/API in trauma patients with suspected LEVI as a screening tool to safely avoid unnecessary CTA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      A retrospective cohort study of all lower extremity trauma patients with soft signs of LEVI who presented to Charlotte Maxeke Johannesburg Academic Hospital from February 1, 2018 to January 31, 2020 was undertaken.
