Indirect causes contain changes in tissue, neighborhood obstruction of blood vessels due to factors like thrombi, emboli, and stenosis, and compromised immunity in AIDS patients, increasing the danger of gangrene formation.Wet gangrene is regularly as a result of acute occlusion due to trauma, restrictive bandages, or peripheral vascular disease.
