The aim of this study was to examine the patient-centered outcomes after isolated inframalleolar interventions. METHODS A database of patients undergoing lower extremity endovascular interventions for tissue loss (critical limb-threatening ischemia, Wound, Ischemia, and foot Infection [WIfI] stage 1-3) and a de novo intervention on the index limb between 2007 and 2017 was retrospectively queried. Those patients with isolated inframalleolar interventions on the dorsalis pedis and medial and lateral tarsal arteries were identified. Patients with concomitant superficial femoral artery and tibial interventions were excluded. Intention-to-treat analysis by patient was performed. Patient-oriented outcomes of clinical efficacy (absence of recurrent symptoms, maintenance of ambulation, and absence of major amputation), amputation-free survival (AFS; survival without major amputation), and freedom from major adverse lime revascularization, and absence of end-stage renal disease. Those in whom the primary wounds or the initial amputation site failed to heal ultimately underwent below-knee amputations. The clinical efficacy was 25% ± 7% (mean ± standard error of the mean) at 5 years. The 5-year AFS rate was 33% ± 8%, and the 5-year freedom from major adverse limb events was 27% ± 9%. On Cox proportional multivariate analysis, predictors for AFS were absence of significant coronary disease, postprocedure pedal runoff score less then 7 (good runoff), WIfI stage less then 3, and absence of end-stage renal disease. CONCLUSIONS Inframalleolar intervention can be successfully performed in high-risk limbs with acceptable short-term results. However, long-term AFS remains poor because of the underlying disease process. BACKGROUND To effectively use administrative claims for healthcare research, clinical events must be inferred from c
