Objective: The purpose of this study was to use a fluorescence imaging system (FIS) (SPYElite, NOVADAQ, US) during lower extremity amputations and develop parameters predict amputation healing, for which there are no proven, objective tests. We hypothesised that the FIS may identify areas poor perfusion at time potential healing complications. There studies involving used in amputation. Method: This prospective cohort involved patients requiring either below- or above-knee-amputation one, mid-western medical centre. as per manufacturer's instructions after wound closure before dressing. Procedure operative management unchanged. Through FIS, values were plotted along site visualise quantify intraoperative compare with 30-day postoperative healing. Results: Surgeons determined all 18 participants had adequate surgical closure. At 30 days, two subjects dehiscence infection; these correlated low on imaging. A further six marginal values, but did not failure. Conclusion: It is feasible amputation, however it perfectly course based vascular perfusion. interesting patterns infection other reduced healed well. Due small sample size, discernible value differences existed between who future, larger show can be predictive patient aid decisions revision.
