Limb Salvage in Diabetic Patients With Ischemic Heel Ulcers.

Abstract

The purpose of this study is to investigate the outcomes of diabetic individuals with ischemic heel ulcers. The study group was composed of a consecutive sample of persons with diabetic ischemic foot ulcers managed by a preset multidisciplinary limb salvage protocol, including revascularization through endovascular technique. The outcome measures were healing, major amputation (above the ankle), and death at 1-year of follow-up. The outcomes between patients with heel ulcers (HUs) and without (NHUs) were compared. A total of 254 patients were recruited. There were 50/254 (19.7%) HUs and 204/254 (79.3%) NHUs. Overall, 190/254 (74.8%) patients healed. The rate of healing for HUs and NHUs was 30/50 (60%) and 160/204 (78.4%); P = .03, respectively. Major amputation occurred in 24/254 (9.4%) patients. The rates of major amputation for HUs and NHUs were 10/50 (20%) and 14/204 (6.9%; P = .002), respectively; 40/254 (15.7%) patients died, unhealed. The rates of mortality for HUs and NHUs were 10/50 (20%) and 30/204 (14.7%; P = .07), respectively. In HUs patients, absence of infection [95% CI = 3.1 (1.6-5.5); P = .002] and superficial ulcers [95% CI = 4.4 (2.2-9.3); P = .0001] were independent predictors of healing, whereas revascularization failure [95% CI = 8.1 (1.5.0-19.4); P = .0001], involvement of the plantar arch [95% CI = 6.3 (2.0-15.4); P = .0001], and dialysis [95% CI = 2.2 (1.3-4.5); P = .006] were independent predictors of major amputation. A multidisciplinary approach achieves good rate of limb salvage in people with diabetic ischemic heel ulcers.
