It is a common knowledge that in 70 percent cases leg ulcers are caused by disease of veins. The veins of leg are those blood pipes which carry back impure and oxygen-deficient blood accumulated in leg, back to heart and then from there to lung for purification and replenishment with oxygen. But in 25 percent cases of leg ulcers, the cause happens to be the disease of artery. The arteries in the leg are those blood pipes which supply pure and oxygen-rich blood to legs and feet. When these arteries become diseased, the supply of pure blood to legs naturally will be disturbed. This decreased supply of pure blood will lead to leg ulcer and gangrene.
Diseases of Artery giving rise to leg ulcer
The disease of arteries is of various types. Firstly if the wall of the artery has inflammatory swelling, the pure blood flowing through it will start clotting and eventually will block the blood flow. This type of inflammatory swelling of arterial wall is called ‘VASCULITIS’ in medical terms. This vasculitis affects small blood pipes (arteries) like those of toes and fingers in majority of the cases.
The other disease of the artery causing leg ulcer is due to accumulation of fat, calcium and cholesterol inside the artery. This leads to decreased blood supply and sometimes almost no supply. In such situation, even minor injury to foot will result into an ulcer that never heals. Such ulcers will heal completely only after blood supply to feet is restored.
Tobacco-chewing or smoking gives birth to leg ulcer
The third important disease of artery is the BURGER’s disease caused by smoking or tobacco-chewing. In cigarette, Bidi and tobacco products like Khaini, Chaini, Zaafaranipatti, Zarda-Mixed Paan Masaala, Mainpuri is contained a very harmful element called nicotine which causes constriction and narrowing of medium-sized and small arteries. With the result, supply of oxygen-rich pure blood to legs and feet becomes negligible in amount. This causes severe leg pain and later on leg ulcer. If this continues without restoring blood supply, the danger of gangrene looms large.
