Prognostic performance of the maximal systolic acceleration at the hallux in healing of foot ulcers: a retrospective cohort study.

The accurate prediction of foot ulcer healing remains a major challenge in clinical practice. To date, no reliable bedside tests are available. The primary aim of this study was to determine the prognostic performance of the maximal systolic acceleration (ACC A single-centre retrospective cohort study was conducted. Patients ≥ 18 years-old who presented with a new-onset ulcer (i.e. Fontaine IV and neuropathic ulcers) on the foot and underwent an ACC In total, 136 patients with 143 wounds were included. Almost half of the patients were diagnosed with diabetes mellitus (47%) and wound infection was present in 42% of cases. After three months of follow-up, a NPV of 97.9%, PLR of 3.25 and NLR of 0.19 was found when applying an ACC ACC
