A few words of thanks would be greatly appreciated.

Gangrene - Definition


Gangrene is a condition that corresponds to cell death (necrosis) which can affect one part of the body, most often a limb or organ (heart, liver, lungs ...). Once blood circulation is stopped in an area (blocked artery, infection) gangrene can happen: oxygen deprived body tissues putrefy. Dry gangrene can be distinguished in particular, where tissues often appear black and is mainly due to the interruption of blood flow through a blocked artery. Wet gangrene is dominated by the presence of oozing, decaying tissue. The ideal is to intervene before gangrene sets in: in advanced cases, however, the restoration of proper circulation may not be sufficient and amputation may be necessary.
