坏疽

坏疽使机体局部组织坏死，炎症可以扩散到从趾到皮下软组织（脂肪、结缔组织）和骨。因多种组织失去活性。因此切除坏死组织手术是必要的。

Gangrenous necrosis involves the tissues of a body part. The inflammation seen here is extending beneath the skin of a toe to involve soft tissue (fat and connective tissue) and bone. Because multiple tissues are non-viable, amputation of such areas is necessary.
