A slow-healing, open sore on the leg, often accompanied by swelling. Leg ulcers are typically caused by insufficient arterial blood supply or by inadequate drainage through the veins. This often painful and disabling condition is a common problem for older people. It is frequently associated with varicose veins, circulation problems, trauma, bacterial infection, long-term immobility, and diabetes mellitus, type 2.
A lingering wound on the leg that heals gradually, typically caused by inadequate blood circulation in that region.
Two primary categories of leg ulcers exist: venous ulcers (also known as gravitational or stasis ulcers) and arterial ulcers. Among these, venous ulcers are notably prevalent, typically emerging close to the ankles and lower legs. These ulcers stem from valve malfunction within veins and commonly manifest alongside varicose veins.
Arising on the foot, arterial ulcers result from inadequate blood circulation within arteries. These ulcers are particularly common in individuals affected by diabetes mellitus and sickle cell anemia.
The approach to treatment is contingent upon the underlying cause of the ulcer. It’s recommended to apply bandages to the affected area to deter infections, reduce swelling, and enhance circulation. If the ulcer is releasing pus, a dressing is placed beneath the bandages and is changed every few days. Additionally, adopting practices like regular exercise, donning support stockings, and elevating the leg while seated can aid in augmenting circulation. Despite these measures, it’s important to note that the healing of a leg ulcer may take several months and recurrence is not uncommon. In exceptional cases, a skin graft might be necessary.
