Using amniotic membrane allografts in the treatment of neuropathic foot ulcers.

Neuropathic foot ulcers are a common complication in patients with diabetes. These ulcers are often slow to heal and can lead to infection, further tissue destruction, osteomyelitis, and amputation. These patients pose a challenge to clinicians who must determine the best treatment options while balancing the risks, benefits, and costs. Conservative therapies often present disappointing results, and a number of newer "biologic bandages" have been developed to better assist the healing process. We describe results from diabetic patients with neuropathic foot ulcers treated with a new amniotic membrane-based allograft.

Clinical outcomes using aggressive approach to anatomic screening and endovascular revascularization in a veterans affairs population with critical limb ischemia.

BACKGROUND: This study sought to examine the impact of an aggressive approach to anatomic screening and endovascular revascularization in a veterans administration population with critical limb ischemia (CLI) on the primary treatments received and overall clinical outcomes. METHODS: The baseline clinical and angiographic characteristics and clinical outcomes of the first consecutive fifty veterans who were referred for the evaluation and treatment of CLI using the strategy outlined were assessed by retrospective review of the computerized medical record and angiographic data. RESULTS: Among the entire cohort, the primary treatments received were as follows--revascularization n = 44 (88%), primary amputation n = 1 (2%), medical treatment n = 3 (6%), and primary minor amputation n = 2 (4%). Endovascular revascularization was the dominant mode of revascularization (94%), with a procedural success rate of 91%. Repeat revascularization was required in 19% of patients who had an initially successful endovascular procedure. A total of eight deaths and four major amputations occurred in the entire cohort over a mean follow-up of 397 +/- 190 days. The 1-year Kaplan-Meier estimates for survival and amputation-free survival for the entire cohort were 90 and 81%, respectively. Resolution of rest pain or complete wound healing was achieved in 85% of patients at a mean of 157 +/-126 days. CONCLUSIONS: An aggressive approach to anatomic screening and contemporary endovascular treatment of CLI resulted in a higher rate of revascularization as the primary treatment for CLI than previously reported, and was associated with high rates of overall and amputation-free survival.
