Evaluation of global limb anatomic staging system for patients with chronic limb-threatening ischemia treated with autogenous bypass grafts

The GLASS stage was not related to patency or the clinical outcomes after distal bypass with vein grafting. Distal open revascularization resulted in excellent rates of freedom from CLTI with low rates of CLTI recurrence, two key time-integrated outcomes of clinical disease severity for patients with CLTI.
