COMS for Chronic Ulcers Treatment

Chronic leg and foot ulcers are defined as wounds that fail to heal in a timely manner, typically persisting for over 4 to 8 weeks without substantial healing despite standard care. These ulcers often result from macro- and microvascular disorders, the most common being chronic venous insufficiency (CVI), alone or with peripheral artery disease (PAD) or microangiopathy. Despite different causes, chronic vascular-origin wounds share similar biological traits and require the same physiological processes for healing. Vascular issues hinder blood perfusion, reducing oxygen, nutrients, and growth factors, leading to decreased energy metabolism and impaired cell functions necessary for proliferation, extracellular matrix production, angiogenesis, and tissue regeneration. Reduced blood supply also limits leukocyte function, compromising the immune response and leading to persistent inflammation and infection. Consequently, these wounds cannot effectively heal, showing prolonged inflammation, persistent infections, and cellular senescence. Best practice wound care includes compression therapy and physical activity for venous ulcers, and angioplasty, surgery, or bypass for arterial ulcers. These treatments aim to improve blood flow, reduce venous stasis, and enhance venous return. Compression therapy and physical activity lower hydrostatic pressure in the lower limb, while angioplasty and surgery remove arterial blockages or create new blood flow routes. Recent studies highlight th…
