Venous Ulcer of the human body is the normal vein with simultaneous valves to prevent the back flow of the blood in the bloodstream rather then regulating a normal course of blood supply in the arteries and veins. The incompetence of the valve regulation causes a back flow that creates congestion and thus lead to ulcer formation at the infected region of the human body. The congestion in the arteries causes excessive pressure over the veins and heart itself doesn't maintain a proper pumping order to let the blood flow forward through arteries and other thin and delicate areas of the body. It's all caused due to venous hypertension of the arteries. The hemoglobin found in red blood corpuscles escapes immediately and starts leaking in the extra vascular space with brownish discoloration or pigmentation of such nature noted. The wound is thus not healed as blood proteins leak and isolate the extra-cellular matrix molecules.
The oxygen and nutrients do not reach to the body-building cells of the body because a substance called fibrin builds-up around the blood vessels and tries to block the path of other nutritional proteins or vitamins and minerals to reach and cure the specific condition of the disease. A leukocyte which means white blood cell insufficiency is caused by it too. A wound turns chronic with reaction with other ingredients found in the blood that are inflamed. The blockage in the blood flow of the arteries enhances the process of having reperfusion injury. The venous stasis ulcer occurs in the crus of the human body. The transudation of inflammatory mediators happens in the subcutaneous tissues formed at the lower extremity including certain tissues of the skin too.

Venous leg ulcers are the specific kinds of ulcers where the human skin looses over the leg portion. The most common criteria for such occurrence is its relationship with the appropriate flow of blood circulation and its non-stop regulation to work efficiently. There are mainly two specific stages of leg ulcer syndrome they are: Chronic and Acute. Acute ulcers follow the normal course of healing process which is less than 4 weeks and include postoperative and traumatic wounds caused due to infectious agents found nearby the region whereas chronic ulcers are those who are perennial in nature and persist often as poor but complex origin type. The ulcers of the leg are triggered by any such injury caused upon due to ill-fitted ski boots which shall be excessively tight and having no rooms for getting fresh air to seep in or the pressure mounted over the leg due to plaster cast used for accidents of the leg region of the human body.
Tuberculosis and Leprosy are caused in a form of bacterial infection and other infectious agents. The names of the bacteria are: eczema and impetigo. A skin biopsy is committed by a dermatologist for possible skin cancer causing such venous ulcer of the leg done at the suspicious lesion edges. The skin diseases are caused due to systemic factors such as vasculitis or sclerosis etc. 'Artery insufficiency' refers to lower blood circulation in the bloodstream and is poor enough to reach the foot region due to atherosclerosis. The fatty acids or other substances get deposits and narrows the arteries in the arterial walls of the vessels. Hypertension; a level of cholesterol in the blood significantly high with inappropriate circulation and consumption of chain-smoking etc. triggers the ulcer of the leg.
'Venous and Diabetic insufficiencies' are the improper functioning of one way valve blood supply of the veins and are caused by arterial damage and blockage. The veins deliver blood from the feet and lowers leg uphill to the heart. It's a calf muscle pumping contingency that clears the path of contracting such ulcers of the feet. A reflux is caused due to it. A sensory neuropathy reduces the awareness of the pressure and causes neuropath ulceration in the leg region.
The risk factors involve standing or sitting for longer span of time; high blood pressure; Obesity; Fractures & injuries to the leg region; Renal failure; Clotting with unregulated circulation disorder of the leg bloodstream vein or capillaries; Excessive swelling in the leg; cerebra- vascular or peripheral vascular disease with history of heart diseases; etc.
The signs/symptoms of venous leg ulcer are the features which characterizes there acuteness for ex: The infectious agents that are found at the inner lower part of an ankle and is located just right below the knee; It surrounds mottled black and brown stains that causes dryness with roughness with itchy feeling and red pigment are experienced; When elevated legs get swollen; Incompetence of superficial venous system; scaling of the feet; oozing of the pus from the ulcers and fissuring process of the leg; the problem of the gravitational force on the feet to allow more blood to ooze out; The feet becomes whitish or bluish with feet shining; Intermittent claudicating process that makes cramps on the feet.
The treatments of leg ulcers include careful assessment of the disease. Surgeries; endovascular laser beam treatment and ultrasound guided sclera therapy of perforated and superficial veins and arteries etc. are the preventive measures for such ulcer formation. Revascularization is enhanced important treatment for ABPI which is less than 0.5
If there is a skin tissue infection antibiotic treatments can be done. The various choices are depended upon on causative organism factor. The resistance increases against the allergies. A latest technology of bio-film has been introduced where bacterial fungus and other organisms' poses trouble embedded in the underlying wound of the leg or ulcerous formation at that specific area. 'Wound dressing' is the specialized dressings in order to assist various stages of the healing. A self-adhering outlook with non-absorbent and absorbent are classified in it. A moist environment is utilized for dressing up the wound
A term Honey dressings is utilized by the doctors to treat the diseases like weeping and contaminated wounds. Contaminations of skin tissues are caused due to dead tissues known as debri-de-ment and surgical prevention is indeed possible to handle upon with wet dressings and certain specific ointments. Larval therapy and maggots could be occasionally recommended by doctors for the healing process of the wound.
Skin grafting is also carefully prepared with a procedure of shaving and removing surrounding skin that causes infectious agents to seep in. Supplements can be consumed in adequate quantities for ex: vitamin C; proteins and minerals and zinc. It can be easily described in the deficiency of the diet. A compression therapy compresses at least 40-70% of chronic leg ulcers. In it a bandage or stocking can be wrapped around the toe or foot region below knee. The ulcer can be treated by accelerating calf muscle pump and heal it and with V.A.C. (vacuum assisted closure) device too.
