Single-institution retrospective review was used to identify amputations for chronic (>1mo) podiatric wounds between 2015-2020. Foot x-ray (MAC) or angiography (SAD) <6 months of index procedure was required. Primary outcomes included major amputation, wound healing, major adverse limb events (MALE), and amputation-free survival (AFS). Statistical analysis included chi-square, one-way ANOVA, non-parametric correlation, Kaplan-Meier, Cox regression, and Akaike (AIC)/ Bayesian Inclusion Criteria (BIC) model comparison. Of 136 limbs, 67 received SAD scores (0-2) and 128 received MAC scores (0-2). SAD cohorts exhibited similar comorbidity profiles with exception of coronary disease, heart failure, and chronic kidney disease. MAC cohorts were notably disparate in prevalence of multiple conditions. High mean SAD/MAC scores were seen in severe (3-vessel) below-ankle disease (p=.001* [SAD], p=.041* [MAC]). Both SAD and MAC correlated with lower mean toe pressure (p=.043* [SAD], p=<.001* [MAC]), while only MAC correlated with higher overall WIfI score (p=.029*). No significant procedural differences were noted. However, higher re-admission rates (73.9% [2] vs. 46.9% [0], p=.014*) and all-cause mortality (65.2% [2] vs. 26.0% [0], p=.002*) were noted with higher MAC. Survival analysis revealed higher one-year major amputation rates (p=.036*), impaired wound healing (p<.001*), and lower amputation-free survival (p=.001*) with increasing MAC severity. Additionally, MAC-2 patients underwent amputation at faster rates than MAC-0 patients (HR 5.25, 95% CI [1.82, 9.77]) with longer times to wound healing (HR 0.21, 95% CI [0.08, 0.53]). Model comparison suggested a combination of WIfI and MAC could improve accuracy of predicted time to major amputation, wound healing, and amputation-free survival. MAC scoring showed significant promise both as individual predictor and adjunct to current predictive models of long-term wound healing outcomes. Routine use of MAC scoring in CLTI evaluation, especially when non-invasive testing is unavailable, could promote timely referral for intervention and efficient resource utilization in limited-resource or critical care settings. Further investigation is necessary to determine MAC's impact on revascularization and how scoring can be used to guide surgical decision making.
