Objective To analyze the clinical effect of infrapopliteal arteries revascularization in patients with limb ischemic ulcer.Methods Clinical data of 152 patients (152 legs) suffering from CLI ischemic ulcer from June 2011 to June 2013 undergoing arterial revascularization using angiosome concept were retrospectively reviewed.Patients were grouped according to runoff,WB angiography,the number of outflow,angiosome model of revascularization and quality of pedal arch.Results Reintervention or ampatation (RAO) rate within 12 months was higher in runoff 0 group that in runoff ＞ 1 group (P ＜ 0.05)and runoff 1 (P ＜0.05).WB (+) group vs WB (-) group of RAO rate within 12 months,ulcer healing rate within 12 months showed no statistical difference.Limb salvage rate within 18 months was higher in WB (+) group than that in WB (-) group (P ＜0.05).Ulcer healing rate within 12 months and limb salvage · rate 18 months in group IRw was lower than group DR (P ＜ 0.05) and group IRc(P ＜ 0.05).RAO rate within 12 month rate was higher in IRw group than in DR group (P ＜ 0.05) and group IRe (P ＜ 0.05).Ulcer healing rate within 12 months and limb salvage rate within 18 months in group NPA was lower than group CPA (P ＜ 0.05) and group IPA (P ＜ 0.05).RAO rate within 12 month rate was higher in NPA group than in CPA group (P ＜ 0.05) and group IPA (P ＜ 0.05).Conclusion The rate of limb salvage was higher in WB (+).IRc revascularization has similar outcome with DR revascularization in ulcer healing rate and limb salvage rate.Clinical effect of CPA and IPA are better than NPA.
