Background: Acute limb ischemia (ALI) is a limb- and life-threatening condition and urgent treatment including revascularization should be offered to patients unless the limb is irreversibly ischemic. The aim of this study was to investigate 1-year clinical outcomes and prognostic factors following revascularization in patients with ALI.Methods and Results: A retrospective, multicenter, nonrandomized study examined 185 consecutive patients with ALI treated by surgical revascularization (SR), endovascular revascularization (ER), or hybrid revascularization (HR) in 6 Japanese medical centers from January 2015 to August 2021. The 1-year amputation-free survival (AFS) rate was estimated to be 69.2% (95% confidence interval [CI], 62.8–76.2%). There were no significant differences among SR, ER, and HR regarding both technical success and perioperative complications. Multivariate analysis revealed that Rutherford category IIb and III ischemia (hazard ratio [HR]: 1.86; 95% CI: 1.06–3.25), supra- to infrapopliteal lesion (HR: 2.06; 95% CI: 1.08–3.95), and technical failure (HR: 2.58; 95% CI: 1.49–4.46) were independent risk factors for 1-year AFS.Conclusions: Rutherford category IIb and III ischemia, supra- to infrapopliteal lesions, and technical failures were identified as independent risk factors for 1-year AFS. Furthermore, patients with multiple risk factors had a lower AFS rate.

Background: Although regenerative cell therapy is expected to be an alternative treatment for peripheral artery disease (PAD), many regenerative cell therapies have failed to show sufficient efficacy in clinical trials. Most preclinical studies have used acute ischemia models, despite PAD being a chronic disease. In addition, aging and atherosclerosis decrease the quality of a patient’s stem cells. Therefore, using a non-acute ischemic preclinical model and stem cells with high regenerative potency are important for the development of effective regenerative therapy. In this study, we assessed the tissue regenerative potential of umbilical cord-derived mesenchymal stromal cells (UCMSCs), which could potentially be an ideal cell source, in a rat model of established ischemia.Methods and Results: The regenerative capacity of UCMSCs was analyzed in terms of angiogenesis and muscle regeneration. In vitro analysis showed that UCMSCs secrete high amounts of cytokines associated with angiogenesis and muscle regeneration. In vivo experiments in a rat non-acute ischemia model showed significant improvement in blood perfusion after intravenous injection of UCMSCs compared with injection of culture medium or saline. Histological analysis revealed UCMSCs injection enhanced angiogenesis, with an increased number of von Willebrand factor-positive microcapillaries, and improved muscle regeneration.Conclusions: These results suggest that intravenous administration of UCMSCs may be useful for treating patients with PAD.
