BACKGROUND: To review patient characteristics and outcomes of in-patient diabetic foot limb salvage and identify risk factors predicting for endovascular limb salvage failure.
METHODS: Retrospective study of limb salvage attempts in 809 patients between August 2013 and July 2015.
RESULTS: Sixty-eight percent of our study population were male with mean age at 65 years and 73% presented with Rutherford grade 6 critical limb ischemia, with the remaining 27% Rutherford grade 5. Eighty-one percent had toe pressures of less than 50 mm Hg, 64% had infrainguinal trans-Atlantic inter-society consensus (TASC II) C or D lesions while 78% had infrapopliteal TASC II C or D lesions. Seven hundred seventy-seven patients (96%) underwent endovascular-first approach limb salvage, with 95% requiring infrapopliteal angioplasty, with 84% of them requiring 2-vessel or 3-vessel revascularization. Thirty-two patients (4%) underwent surgical bypass limb salvage, with 63% performed as salvage procedures for failed angioplasties. The mean in-patient stay was 12.3 days within the endovascular group and 31.1 days within the bypass group (P < 0.01). One-year limb salvage was successful in 88% of endovascular group, as compared with 72% in bypass group (P = 0.01). Overall 1-year survival was 93% within the endovascular group and 88% within the bypass group (P = 0.27). The mean in-patient cost was SGD$5,518 within the endovascular group and SGD$15,141 within the bypass group (P < 0.01). Multivariate analysis showed that independent predictors for failure of endovascular limb salvage include end-stage renal failure (ESRF) (odds ratio [OR] 2.04, P = 0.01), toe pressures <50 mm Hg (OR 2.15, P = 0.01), infrainguinal TASC II patterns C or D (OR 1.99, P = 0.03), and indirect angiosome revascularization (OR 2.03, P = 0.02).
CONCLUSIONS: Within our study population of Asian ethnicity, most in-patient diabetic foot peripheral arterial disease presented with Rutherford grade 6 disease, with mostly TASC II C or D lesions and required infrapopliteal revascularization. As most patients had multiple comorbidities and were poor surgical candidates, the majority underwent endovascular-first approach revascularization. Independent predictors of endovascular limb salvage failure include ESRF, toe pressures <50 mm Hg, infrainguinal TASC II patterns C or D, and indirect angiosome revascularization.
