Question

Why is Gangrene considered more serious and complex condition than necrosis?

​

Answer 1

It is often necessary to remove necrotic tissue surgically, a process known as debridement. When substantial areas of tissue become necrotic due to lack of blood supply, this is known as gangrene.

Gangrene is a clinical condition of ischemic and necrotic tissue, often circumferential around a digit or extremity. It is identified by discolored or black tissue and associated sloughing of natural tissue planes. The three main types of gangrene are wet gangrene, dry gangrene, and gas gangrene.
