Of the cohort, 352 patients, 383 limbs, had self\u2010expanding nitinol stents implanted for CTOs in the SFPA and were followed for 5 years.

In total, 58% of the patients had diabetes mellitus and 25% were patients with critical limb ischemia. Occluded length was 194\u2009\u00b1\u200989 mm, mean total stent length was 198\u2009\u00b1\u20097 mm, and mean stent diameter was 7.1\u2009\u00b1\u20090.9 mm. Five\u2010year primary and secondary patency rates were 51.8 and 79.5%, respectively, and the rates of freedom from bypass surgery, major or minor amputation, and all\u2010cause death were 96.1, 96.2, and 78.4%, respectively.
