    Abstract:
    BACKGROUND: The etiology of chronic leg ulcers is heterogenous and they exhibit quite different healing rates depending on the underlying cause. Although the prevalence and incidence of chronic leg ulcers appear to be increasing, data on these patients in Germany are lacking. PATIENTS AND METHODS: Altogether 100 German wound care professionals were asked to complete a questionnaire regarding the diagnosis and etiology of their patients with chronic leg ulcers. RESULTS: We received the data on 31,619 patients. In these patients, venous insufficiency was the dominating causative factor in 47.6 % and arterial insufficiency in 14.5 %, 17.6 % of ulcers were due to combined arterial and venous insufficiency. Rarer causes included vasculitis (5.1 %), exogenous factors (3.8 %), pyoderma gangrenosum (3.0 %), infection (1.4 %), neoplasia (1.1 %), calciphylaxis (1.1 %) and drug-induced (1.1 %). The used diagnostic methods used varied widely between the medical and surgical specialties. CONCLUSIONS: Even though the results of our study cannot claim to be a representative overview, they demonstrate clearly that next to known etiologies, e. g. chronic venous insufficiency or peripheral arterial insufficiency, which are relevant in 79.7 % of all patients a multitude of other causes exist, which are responsible in 20.3 % of all patients for the development of chronic leg ulcers.
