Wet gangrene is usually Rapidly develops due to obstruction of venous and/or arterial blood flow. The affected part is filled with stagnant blood, which promotes the rapid growth of bacteria. The toxic products formed by the bacteria are absorbed causing systemic manifestations of sepsis and eventual death.
