Arterial Wounds

Arterial wounds are challenging because they are not likely to heal until blood flow is improved or restored. These wounds are typically very painful and often appear ‘punched out.’ The legs and feet can be hairless, toenails may be thickened, and the skin can be dry. These types of wounds usually require a referral to a vascular specialist. Gangrene is a specific type of arterial wound. A gangrenous wound occurs when there is not enough blood flow to support the tissue. Essentially, the tissue is being starved of the nutrients and oxygen it needs to survive, and the tissue dies. When a wound is black or gangrenous, the goal is to prevent infection until blood flow can be restored. “Painting” a wound with an iodine-based antiseptic is a common treatment for these types of wounds.
