Preventing recurrence of leg ulcers in older adults with peripheral vascular disease: identifying predictors and evaluating strategies.

外周血管疾病--四肢的动脉和静脉疾病--会导致1-4%的60岁以上成年人患上慢性腿部溃疡。溃疡很慢，很难愈合，愈合后，高达70%的溃疡复发，许多溃疡在几周内复发。这项研究的目的是确定预测因素和评估预防慢性腿部溃疡复发的策略；并提高我们对患有慢性腿部溃疡的成年人的生物学、局部疾病和健康之间的关系的理解。

Peripheral vascular disease – disease of the arteries and veins in the limbs – leads to chronic leg ulcers for 1–4% of adults aged over 60. The ulcers are slow and difficult to heal and after healing, up to 70% recur, many within a few weeks. The aim of this research is to identify predictors and evaluate strategies to prevent recurrence of chronic leg ulcers; and improve our understanding of relationships between biology, localised disease and health in adults suffering from chronic leg ulcers.
