This study states that Endovascular tibial interventions for chronic limb-threatening ischemia are frequent, but the implications of early failure (≤30 days) of an isolated tibial intervention are still unclear. The aim of this study was to examine the patient-centered outcomes after early failure of isolated tibial artery intervention. A database of patients undergoing lower extremity endovascular interventions between 2007 and 2017 was retrospectively queried. Patients with chronic limb-threatening ischemia (Rutherford classes 4, 5, and 6) were selected, and failures within 30 days were identified. Lack of technical success at the time of the procedure was an exclusion. 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 (survival without major amputation), and freedom from major adverse limb events (MALEs; above-ankle amputation of the index limb or major reintervention [new bypass graft, jump or interposition graft revision]) were evaluated.
