Venous Ulcers: These ulcers are formed in legs due to insufficient venous flow due to various causes like varicose veins, deep venous thrombosis, or vacuities affecting veins.
Normal veins contain valves, which prevent back flow of blood and pump blood towards heart, when veins become dilated, inflamed or blocked by clots; these valves are unable to function and blood pools in leg veins.
This pooling of blood results in edema or swelling of legs, blood products oozes out of the vessel, these include proteins, fibrinogen and inflammatory substances which cause inflammation and break down normal tissues resulting in their destruction, this also interrupts the oxygen supply of tissues resulting in further damage and non healing of ulcers.
Risk factors for venous ulcers are obesity, prolonged recumbent position, smoking or alcohol use, pregnancy, old age and diabetes. These ulcers are painful, prone to infection and difficult to treat and often recur after treatment, patient has painful shallow ulcers, with surrounding skin edema and redness.
