Résumé
The present study aimed to determine the preferred initial revascularization procedure between bypass surgery and endovascular therapy (EVT) in patients with chronic limb-threatening ischemia (CLTI) categorized as indeterminate according to the Global Vascular Guidelines (GVG). We retrospectively analyzed the multicenter data of patients who underwent infrainguinal revascularization for CLTI categorized as indeterminate according to the GVG between 2015 and 2020. The end point was the composite of relief from rest pain, wound healing, major amputation, reintervention, or death. A total of 255 patients with CLTI and 289 limbs were analyzed. Of the 289 limbs, 110 (38.1%) and 179 (61.9%) underwent bypass surgery and EVT, respectively. The 2-year event-free survival rates with respect to the composite end point were 63.4% and 28.7% in the bypass and EVT groups, respectively (P < 0.01). Multivariate analysis revealed that increased age (P = 0.03); decreased serum albumin level (P = 0.02); decreased body mass index (P = 0.02); dialysis-dependent end-stage renal disease (P < 0.01); increased Wound, Ischemia, and foot Infection (WIfI) stage (P < 0.01); Global Limb Anatomic Staging System (GLASS) III (P = 0.04); increased inframalleolar grade (P < 0.01); and EVT (P < 0.01) were independent risk factors for the composite end point. In the WIfI-GLASS 2-III and 4-II subgroups, bypass surgery was superior to EVT with regard to 2-year event-free survival (P < 0.01). Bypass surgery is superior to EVT in terms of the composite end point in patients classified as indeterminate according to the GVG. Bypass surgery should be considered an initial revascularization procedure, especially in the WIfI-GLASS 2-III and 4-II subgroups.

BACKGROUND
The present study aimed to determine the preferred initial revascularization procedure between bypass surgery and endovascular therapy (EVT) in patients with chronic limb-threatening ischemia (CLTI) categorized as indeterminate according to the Global Vascular Guidelines (GVG).
METHODS
METHODS
We retrospectively analyzed the multicenter data of patients who underwent infrainguinal revascularization for CLTI categorized as indeterminate according to the GVG between 2015 and 2020. The end point was the composite of relief from rest pain, wound healing, major amputation, reintervention, or death.
RESULTS
RESULTS
A total of 255 patients with CLTI and 289 limbs were analyzed. Of the 289 limbs, 110 (38.1%) and 179 (61.9%) underwent bypass surgery and EVT, respectively. The 2-year event-free survival rates with respect to the composite end point were 63.4% and 28.7% in the bypass and EVT groups, respectively (P < 0.01). Multivariate analysis revealed that increased age (P = 0.03); decreased serum albumin level (P = 0.02); decreased body mass index (P = 0.02); dialysis-dependent end-stage renal disease (P < 0.01); increased Wound, Ischemia, and foot Infection (WIfI) stage (P < 0.01); Global Limb Anatomic Staging System (GLASS) III (P = 0.04); increased inframalleolar grade (P < 0.01); and EVT (P < 0.01) were independent risk factors for the composite end point. In the WIfI-GLASS 2-III and 4-II subgroups, bypass surgery was superior to EVT with regard to 2-year event-free survival (P < 0.01).
CONCLUSIONS
CONCLUSIONS
Bypass surgery is superior to EVT in terms of the composite end point in patients classified as indeterminate according to the GVG. Bypass surgery should be considered an initial revascularization procedure, especially in the WIfI-GLASS 2-III and 4-II subgroups.
