Vascular Wound Care Specialist in Los Angeles
Non-healing wounds usually form on the back of the lower leg between the calf and ankle, causing itchiness, leg pain, and skin discoloration. While it’s true that these wounds can be caused by injury or other conditions like diabetes, chronic lower extremity wounds that take more than 2 weeks to heal or that lead to progressively worsening skin breakdown are more than likely attributable to underlying vascular disease, and therefore benefit significantly from vascular wound care. In fact, vascular disease contributes to more than 90% of chronic wounds.
Obstructed blood flow is the unifying disease process in many vascular diseases, underpinning peripheral artery disease (PAD) in the arteries, chronic venous insufficiency wounds (CVI) in the veins, and a number of other localized vascular conditions like May-Thurner Syndrome and venous thromboembolism. Throughout the course of several years, these diseases disrupt blood flow to tissues, eventually damaging skin, muscles, and nerves due to lack of adequate blood supply. Over 8.5 million people in the US suffer from PAD and more than 6 million live with CVI [1,2].

Arterial Wound vs Venous Wound
Skin ulceration can occur when either veins, arteries, or both malfunction. Many are surprised to learn that venous insufficiency contributes to approximately 70% of vascular wounds, while arterial disease accounts for 5 to 10%. At the same time, as many as 26% of leg ulcers have both venous and arterial causes [3,4].
Causes of Arterial Wounds
Causes of Venous Wounds
Ultimately, CVI results in limited blood flow toward the heart. Without the ability to return blood back to the body’s main circulatory pump, blood pools in the extremities and backs up in the veins. The increased blood volume surpasses the veins’ natural reservoir capacity and exerts increased pressure on the vessels, causing undue stress and eventual failure. As more of the venous system is affected and blood flow is further compromised, skin color changes in the lower leg and wounds form as tissue breaks down. Risk factors for venous wound formation include: older age, sedentary lifestyle, high body mass index, arterial hypertension, deep vein thrombosis, deep vein reflux, and a family history of venous leg wounds .
Signs & Symptoms of Vascular Wounds
Arterial wounds typically develop over bony parts of the foot as well as the heels and toes, past the point of vessel occlusion. These can be shallow or deep skin wounds with or without gangrene. Arterial wounds have well-defined edges and appear to be “punched out.” The center of the wound, the wound base, is pale in color (grey or yellow). Skin surrounding the arterial wound may be red, cold to the touch, shiny, and hairless .
As vein disease increases in severity, constant swelling, fat destruction (lipodermatosclerosis), and skin discoloration and deterioration occur anywhere between the knee and ankle [4, 7-9]. Appearance-wise, the skin surrounding the wound looks shiny, thin, hairless, and hyperpigmented with a brown color. The wound itself has sloping edges, and exudate fluid may ooze from the wound. Venous wounds are shallow and irregularly shaped. Pain is usually less severe compared to arterial wounds unless there is an active infection or excessive swelling.
Vascular Wound Care & Treatments
Treating vascular wounds isn’t just about addressing the visible leg ulcer, but also the underlying disease process that created them in the first place. The root cause of arterial and venous wound formation is vascular disease such as advanced peripheral artery disease and chronic venous insufficiency. However, many lower extremity wounds have a multifactorial set of causes (in addition to vascular disease), and therefore require multiple, simultaneous treatment approaches.
A multidisciplinary team consisting of wound care specialists, podiatrists, physical therapists, primary care physicians, and vascular interventionalists will provide the best care for a patient suffering from venous or arterial leg ulcerations attributable to vessel disease [2-3,10]. Vascular interventionalists include general and vascular surgeons, who are best-suited to treat advanced vessel disease through invasive surgeries. They also include interventional radiologists, who specialize in minimally invasive approaches to improve blood flow.

Lifestyle Changes and Medicine
Arterial Wound Care
Patients who present with open, non healing arterial wounds are typically referred to a wound doctor who will clean the wound routinely and dress it with bandages to prevent infection and promote healing of the skin. Arterial wound dressing changes do not target the underlying arterial disease that causes the wounds, however, arterial wound care is still an essential part of healing and complements other treatments.

Venous Wound Care
Patients who present with open, non healing venous wounds are typically referred to a wound care specialist who will clean the wound routinely and dress it with bandages to prevent infection and promote healing of the skin. Changes to the wound dressing for venous leg ulcers do not target the underlying vein disease that causes venous ulceration, however, venous wound care is still an essential part of healing and complements other treatments.
