Types of Chronic Wounds
Venous Ulcers
Venous
ulcers can also be referred to as stasis, insufficiency, or varicose ulcers,
and they develop when the valves inside the veins of the lower extremities do
not work sufficiently, resulting in backflow This process leads to blood
pooling in the veins, followed by swelling and the development of an ulcer.
Arterial Ulcers
Arterial,
or ischemic, ulcers are caused by poor perfusion of nutrient-rich
blood to the lower extremities that leads to tissue damage as the tissue
becomes oxygen
deprived.
Diabetic (Neuropathic) Foot Ulcers
Neuropathic
foot ulcers are the result of the loss of peripheral sensation, or local
paresthesias, in patients with diabetes. This loss of sensation causes extended
microtrauma, the breakdown of overlying tissue, and the eventual formation of
an ulcer.
Pressure Injuries/Ulcers
Pressure
injuries are localized areas in which there is tissue damage resulting from
prolonged pressure, shear, or friction, usually on bony prominences, that
causes the tissue to compress.
