Résumé
PURPOSE: Diabetic foot ulcers are one of the most important complications of patients with diabetes for their quality of life. Yet the data on factors that affect the treatment outcome and the guidelines for a multidisciplinary approach are limited. The purpose of this study was to assess the clinical characteristics that affect healing of diabetic foot ulcers, and especially when this is associated with peripheral arterial disease (PAD). METHOD: We retrospectively reviewed the clinicopathologic data of 112 patients who were admitted for the treatment of diabetic foot ulcers from May 2004 to December 2007 at Bundang Seoul National University Hospital. The patient's demography and co-morbidities, the laboratory and radiological details, the surgical data and the treatment outcomes were evaluated and analyzed according to the presence of PAD. RESULT: The mean age of the patients was 66 years old and the male to female ratio was 2.3:1. Except for simple dressing of the ulcers, skin graft, amputation or revascularization were performed for 77 patients. Ulcers healed in 74 patients (66.1%) and recurrence was observed in 42 patients (37.5%). Major amputation was performed on 11 patients (9.8%). The non-healing group had a higher incidence of male gender (P=0.049), end stage renal disease (P=0.038), coronary arterial disease (P=0.018), the presence of PAD (P=0.034) and a higher level of cholesterol (P=0.011) and triglyceride (P=0.039). Patients with PAD had a lower ankle-brachial index (P<0.001) and a higher rate of undergoing revascularization (P<0.001), overall amputation (P=0.003), non-healing (P=0.034) and recurrence (P<0.001). After revascularization, the rate of major amputation was not reduced (P=0.915). CONCLUSION: The risk of non-healing, overall amputation and recurrence is increased in the presence of PAD. Evaluating the PAD status and multidisciplinary treatment strategies are needed to treat these patients with diabetic foot ulcer.
