What is the pathophysiology of gangrene?
Moist gangrene develops when the blood supply is suddenly cut off, as by a severe burn or an arterial blood clot. Tissue that has not been destroyed by the trauma begins to leak fluids, which then foster the growth of bacteria. The affected area becomes swollen and discoloured and later becomes foul-smelling.
What is pathology behind dry gangrene?
Dry gangrene occurs when the blood supply to tissue is cut off. The area becomes dry, shrinks, and turns black. Wet gangrene occurs if bacteria invade this tissue. This makes the area swell, drain fluid, and smell bad.
