Wound Care Experts: Non-healing Leg Or Ankle Wounds
Research has shown that about 70% of people who seek care at Wound Care Centers have an underlying circulation issue in the foot or leg. This can be either on the arterial or on the venous side. Unfortunately, the current practice in most wound care centers is that this circulatory problem is not diagnosed or considered until after months of futile debridement and dressing changes have failed to achieve long term healing.
In an effort to best treat non-healing leg wounds it is critical for patients to have their circulation evaluated by a Vascular Surgeon. This is even more important in patients aged 50+, if there has EVER been a history of smoking, diabetes, or hypertension. This evaluation must be done at the very start of a wound care patient’s treatment and not be put off until after other approaches have failed.
How do we test if slow healing foot wounds are connected to a vascular problem?
Testing for circulation is a non-invasive, ultra-sound based process and can be done, in most cases, in under an hour. Testing is pain free and does not involve the use of any drugs and or anesthesia. Using simple sound waves a Registered Vascular Ultrasonographer can easily scan for circulatory deficiencies and provide your physician with the critical information they need to develop a plan for how to best approach healing your wounds.
Non-healing leg wounds and ulcers fall into several different categories:
- Diabetic Wounds: If you have diabetes, you may be prone to foot ulcers since you may not have protective sensation on
your feet. Causes of foot ulcers include excessive pressure or rubbing against the skin that may result from wearing ill- fitting shoes or walking barefoot.
- Arterial Wounds: Complete or partial arterial blockage can lead to ulcers. If you have arterial disease, you may have tests to measure blood flow or to locate a blockage in your arteries.
- Venous Wounds: These ulcers are usually a symptom of venous disease, where the veins in your legs are compromised, causing blood to build up. Typical venous ulcers appear near the ankle and are often painful.
Vein problems cause most of the ulcers on the legs treated in wound care centers. These wounds are called “venous stasis ulcers”, because they are located in the middle or lower part of the leg, usually above the ankle. These ulcers may be quite large (5-10 cm diameter) and may be “ugly” in appearance, but they are usually not painful. If there is associated pain, the pain is frequently relieved by elevation of the extremity. The skin around these ulcers may be brownish in color and may be firm to touch (not soft and supple), for many years before the ulcer begins. A common cause of leg ulcers is reflux (abnormal blood flow) in the veins of the leg, specifically the saphenous vein. This problem can be treated permanently by the physicians at Treasure Coast Heart & Vascular with an out-patient procedure done in the office. Otherwise, venous leg ulcers tend to recur over time, especially if an appropriate treatment regimen with compression hose has not been followed. With venous leg ulcers, the risk of limb loss is low.
Arterial ulcers are usually very painful. They are most often located in the foot or toes, i.e. further from the blood flow pump (the heart). Pain is the primary complaint for these patients, especially pain at night if their foot is not kept below the heart. In fact, many patients tell us they sleep with the foot hanging off the bed, to relieve their pain. The wound itself may be small (1-2 cm diameter), and is usually dry. For example, it may be just the tip of a toe. These wounds do not often look as “ugly” as a venous leg ulcer, because there is not enough blood flow to make pus or drainage. The skin around the wound is sometimes red, tender, and swollen, because bacteria can get through the skin and invade the surrounding tissues. This problem needs urgent treatment, and the risk of limb loss is high.
Diabetes patients also frequently get ulcers and wounds of the foot and toes, but that is primarily because of poor sensation
(numbness) of the feet. The technical term for this numbness is “peripheral neuropathy.” Many of these patients also have arterial problems, with resultant poor arterial blood flow. This group of patients is at especially high risk of limb loss. Treasure Coast Heart & Vascular is recognized as the leading amputation prevention center in St Lucie and Martin Counties.
