Gangrene is the localised death of body tissue due to a lack of blood flow or a serious bacterial infection. It commonly affects the arms and legs, including the toes and fingers, but it can also occur in the muscles and in organs inside the body, such as the gallbladder.
One of the types of gangrene,the dry gangrene occurs due to prolonged ischemia of the body tissues with insufficient blood supply.It presents as dry and shriveled skin that looks brown to purplish blue or black. It usually affects the fingers and toes of patients with diabetes or blood vessel disease, such as atherosclerosis.
Shown in the picture is a patient diagnosed with Ischemic necrosis and gangrene of fingers in its critical form.He was previously suffering from atherosclerosis and declined to undergo further surgical treatments for the gangrene. He instead elected for conservative treatment with analgesia,an anti-platelet agent,and management of his vascular risk factors.
