Updates in Arterial Ulcers.

Arterial ulcers are a clinical symptom of a complex array of underlying comorbid factors, namely peripheral artery disease (PAD). Chronic limb-threatening ischemia is representative of end-stage PAD. Ulcers of other etiologies can carry an arterial component, mandating recognition of risk factors, a comprehensive history and physical examination, and appropriate diagnostic testing in lower extremity ulcers. The primary therapy for arterial ulcers is re-establishment of in-line arterial flow, achieved by endovascular therapy or open revascularization. Medical management is essential to slow disease progression, and topical therapies are crucial to promote rapid ulcer closure and reduce infection risk.
