Types of Chronic Wounds

Some of the more common types of chronic wounds include the following:

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. 

Conclusion

Understanding how these types of chronic wounds differ and their root causes is essential to determine the most appropriate and effective course of treatment for optimal healing and best clinical outcomes.
