{Abstract}: Objectives: The aim of this study was to evaluate the relationship between absolute lymphocyte count (ALC) and outcomes of infrainguinal bypass surgery for chronic limb-threatening ischemia (CLTI). Methods: From 2004 to 2020, 209 limbs of 189 patients who underwent infrainguinal bypass surgery for CLTI and whose ALCs were available were included. Patients with survival >2 years and limb salvage >2 years were considered discriminant groups, and an ALC cut-off value was calculated. The relationship between preoperative ALC and outcomes was evaluated. Results: Survivorship of the higher ALC group was significantly higher than that of the lower ALC group (cut-off value 1030/μL, p = 0.0009). The limb salvage rate of the higher ALC group was significantly higher than that of the lower ALC group (cut-off value 1260/μL, p = 0.0081). In the dialysis patient group (103 limbs), the limb salvage rate of the higher ALC group was significantly higher than that of the lower ALC group (cut-off value 1170/μL, p = 0.026). ALC was independently associated with limb loss in multivariate analysis. Conclusion: ALC is promising as a predictor of outcomes after bypass surgery in CLTI. In particular, ALC is expected to be useful for limb prognosis in hemodialysis patients.
