Venous Ulcers

Venous Leg Ulcers (VLUs) are among the most widespread chronic lower extremity wounds, with approximately 70% of chronic leg ulcers reported as VLUs. Across the population in the western hemisphere, it's estimated that 2% have VLUs, while those in the aging population have a greater prevalence at 5%. In the United States, 6 million people struggle with these wounds, a number dwarfed by those in other countries. For instance, in Africa, approximately 25-135 million individuals have VLUs.

Vascular ulcers are wounds on the skin that form as the result of abnormal blood circulation in the body, including arterial and venous etiologies. Estimates suggest 3-5% of those over 65 in the United States have a vascular ulcer. Of those with peripheral arterial disease, approximately 20-70% have chronic wounds, according to data up to 2018. Since arterial ulcers may be underdiagnosed, certain experts theorize that the number of chronic wounds developed due to arterial insufficiency is higher in reality.

Acute wound: An alteration in skin integrity, such as a simple laceration or a surgical wound, that typically moves through the healing process and heals in a predictable timeframe without complication. An acute wound results from a documentable event with the assumption that it will progress normally through the 4 phases of wound healing.

We all know that compression therapy is the “gold standard” for the treatment of venous leg ulcers. However, how do we know if we should apply compression, how much compression, and what type of compression?

Heel pressure injuries and various forms of ulcers are easy to identify, but are you overlooking sleeping position as a cause for wounds in other locations? Do you have a wound you are sure is venous but has normal venous insufficiency testing results and fails to respond to compression? Can pressure while sleeping slow or stop healing in your patients with venous and arterial wounds? Do you ask patients about their sleeping position in your history taking and physical examination? After reading this article, you will be able to ask patients about their sleeping habits and heal more wounds with that knowledge

Moist wound healing is the current cost-effective, evidence-based modality to achieve faster wound healing rates and decreased pain and infection. As part of the wound healing process, acute wounds produce reparative exudates consisting of growth factors to support extracellular matrix production; in contrast, chronic wounds contain inflammatory-producing exudates studded with cytokines and proteases that may help maintain the inflammatory phase but can exert destructive effects on the fragile wound bed and may extend to the periwound surface.

Infection is the single most likely cause of delayed healing in chronic wounds. In most cases, identification of chronic wound infection (e.g., diabetic foot ulcers and venous leg ulcers) is not obvious because chronic wounds do not exhibit the same classic inflammatory signs of infection as those found in acute wounds. More arduously, those common signs of infection—pain, erythema, heat, and purulent exudate— vary as we age and occur differently in those with underlying diseases or weakened immune systems. Diagnosis is generally based on the doctors’ experience and could be confirmed with microbiological culture of tissue biopsy. However, culture could take a few days, and the results may not always be reliable because of sampling error. A fast and accurate diagnosis of wound infection would relieve the patient of significant discomfort and improve the treatment outcome.

Predominant pain pattern, ulcer location, ulcer appearance, type and amount of wound exudate, and vascular and sensorimotor assessment are some key factors used to determine the primary etiology of lower extremity ulcers.

Lower extremity wounds manifest in a multitude of ways, with numerous causative or trigger factors. These types of wounds are often costly to treat, are frequently refractory, and have a high risk for recurrence. A comprehensive assessment and an evidence-based treatment plan, along with ongoing patient education and routine follow-up, are essential components of an effective plan of care.

Arteriography: Also called angiography, this technique is the medical imaging of blood vessels to look for aneurysm and stenosis.

Hemosiderin staining: Hemosiderin staining results in a red, ruddy appearance on the lower leg and ankle. This appearance is caused when red blood cells are broken down and not removed adequately as a result of venous insufficiency or another medical condition.

Phlebectomy: A minimally invasive procedure (usually outpatient) to remove varicose veins located near the surface of the skin.
