Dry Gangrene Treatment

Dry gangrene is identified by dry and wrinkly skin that may appear in a range of colors from brown to purple to black. This form of gangrene tends to develop slowly and results from reduced blood flow. The most common cause of dry gangrene is a blood vessel disease, like atherosclerosis. Surgery to restore blood flow and remove the diseased tissue is the primary treatment.

  1. Prognosis

    • Dry gangrene has an especially good prognosis because it usually does not involve a bacterial infection and it progresses more slowly than other forms. Early treatment is vital to ensure the best outcome.

    Surgery

    • Your surgeon will remove the dead tissue to keep the gangrene from spreading. He might also fix any damaged blood vessels that were preventing proper blood flow to the affected area. If the gangrene has damaged your skin extensively, you might need a skin graft from another part of your body. The skin usually comes from an area typically covered by clothing. You can only receive a skin graft if sufficient blood supply has been restored to the damaged area.

    Medications

    • If there is any risk of infection, you will receive IV antibiotics. Pain medications, fluids and nutrients are also administered if necessary.

    Post-Surgery and Prevention

    • After your operation, follow the doctor's instructions regarding cleaning the wound and changing bandages. Keep the affected area clean. If your doctor prescribes any antibiotics, be sure to take as instructed and finish the whole course of treatment. Limit your activity for a few days.
      Dry gangrene is the result of an underlying condition that affects the blood vessels so it is possible it can always return, but you can do certain things to reduce a recurrence. Manage your underlying condition as best you can. Do not smoke; it damages your blood vessels. Frostbite inhibits proper blood circulation and can lead to gangrene. Pay close attention to your skin after prolonged exposure to cold conditions; contact your doctor if you notice that your skin is pale, hard, cold and numb.
