Treatment of gangrene

Treatment of gangrene

How much of a limb or digit can be salvaged depends on the blood supply proximal to the gangrene. Poor circulation should be improved by surgical revascularisation, enabling a more conservative debridement or distal amputation. However, major limb amputation may be required in the presence of life-threatening sepsis, when the blood supply cannot be improved or in patients whose limb is non-functional because of contractures, stroke, etc.
