The objective of this observational registry is to track the clinical progression of chronic limb-threatening ischemia (CLTI) and incidence of death, amputation, and revascularization attempts over a one-year period.
The study population is comprised of Rutherford 5 and 6 CLTI subjects who have hemodynamic evidence of severely diminished arterial inflow of a peripheral limb and:
1. 2 revascularizations in the last 6 months that failed to resolve symptoms, OR
2. have inadequate popliteal, tibial, or pedal revascularization target
