|Arteries bring oxygenated blood from the heart to the tissues
|Veins return blood to the heart
|Limb Threatening Condition- Leg loss above/below knee if untreated
|NON-Limb Threatening Condition
|Typical wounds begin at toes and progress up the foot
|Wounds of CALF and ANKLE, associated with brown/red/purple skin discoloration and texture changes from the ankle to the knee
|Cause is lack of arterial blood flow/oxygen to the tissues preventing healing. The tips of the toes have the worst blood flow, so the wounds tend to start there.
|Cause is damaged vein valves, which lead to swelling when sitting or standing. Swelling damages the skin and causes wounds.
|Treatment- Must improve the arterial blood flow to the toes either with minimally invasive balloons and stents or bypass surgery
|Treatment- COMPRESSION, COMPRESSION, COMPRESSION
These wounds will not heal without compression bandages such as a multilayer wrap, regardless of the wound products used on the wound
|Good wound care after improving the blood flow will allow the wounds to heal
|Evaluate veins with ultrasound and possibly inject dye in veins- sometimes can seal off a superficial vein or stent a narrow vein to help heal or prevent the wounds from reoccurring.
