Amputation-Free Survival, WIfI Stage, and GLASS Classifications in Distal Crural or Pedal Bypass for Chronic Limb-Threatening Ischemia

: Distal crural and pedal bypasses are essential for limb salvage in high-risk CLTI patients, particularly those with failed prior revascularization. However, the procedure is associated with limited long-term amputation-free survival. WIfI and GLASS classifications are useful for stratifying risk and guiding treatment, but outcomes suggest the need for individualized care strategies. Further research into perioperative management and alternative interventions is warranted to improve long-term outcomes in this population.
