%X BACKGROUND: To examine the influence of liver function on patients with chronic limb-threatening ischemia (CLTI), we classified patients with CLTI after revascularization according to their modified albumin-bilirubin (ALBI) grades.
METHODS: We retrospectively analyzed single-center data of patients who underwent revascularization for CLTI between 2015 and 2020. Patients were classified with ALBI grades 1, 2a, and 2b and 3 according to the ALBI score, which was calculated, based on serum albumin and total bilirubin levels. The endpoints were the 2-year amputation-free survival (AFS) and 1-year wound healing rates.
RESULTS: We included 190 limbs in 148 patients, and 50, 54, and 86 cases were assigned as grade 1, 2a, and 2b and 3, respectively. The 2-year AFS rates for the grade 1, 2a, and 2b and 3 groups were 79 ± 6%, 66% ± 7%, and 45 ± 6%, respectively (P < 0.01). One-year cumulative wound healing rates for grade 1, 2a, and 2b and 3 groups were 68 ± 7%, 69% ± 6%, and 48% ± 5%, respectively (P = 0.01). Multivariate Cox proportional hazard analyses identified age (≥75 years), dependent ambulatory status, and modified ALBI grades 2b and 3 compared with grades 1 and 2a as significant independent predictors of AFS. The dependent ambulatory status and Wound, Ischemia, and foot Infection classification stage 4 were significant negative predictors of wound healing.
CONCLUSIONS: Many patients with CLTI had high modified ALBI grades, and impaired liver function classified as modified ALBI grade 2b and 3 is a robust negative predictor of AFS.
