Patients with CLI have a poor prognosis, the estimated 3-year probability of mortality being 35.1%. As a result, preference to less burdensome endovascular treatment should be given, provided the same levels of symptomatic improvement can be achieved as with open surgery. Objective performance goals for the first year following revascularisation include an amputation-free survival rate of 76.5%, a limb preservation rate of 88.9% and an overall survival rate of 85.7%
