Stem Cell Therapy: A Possible Role in the Treatment of Patients with Chronic Limb-Threatening Ischemia?

Chronic limb-threatening ischemia (CLTI) is a severe form of peripheral arterial disease that portends high morbidity and mortality. Patients may undergo various endovascular or open procedures with the goal of limb salvage. No-option CLTI patients represent a vulnerable population for whom conventional options have been exhausted, or anatomy precludes any attempts at revascularization, often resulting in amputation.
