What are the characteristics of an arterial ulcer?
What are the characteristics of an arterial ulcer?
Distinguishing features of arterial ulcers include: Located on the lower legs and tops of the feet or toes. A tendency to be painful, particularly at night. A symmetrical shape with well-defined borders, often described as having a ‘punched-out appearance’
Where do arterial ulcers appear most often?
Arterial ulcers are often very painful, they are often on the foot, around the ankle, sometimes the lower leg. The pain from them can be worse at night, and patients hang the leg out of bed or sleep in a chair to get relief from this night pain.
How can you tell the difference between a venous and arterial ulcer?
Arterial ulcers develop as the result of damage to the arteries due to lack of blood flow to tissue. Venous ulcers develop from damage to the veins caused by an insufficient return of blood back to the heart. Unlike other ulcers, these leg wounds can take months to heal, if they heal at all.
Are arterial ulcers pale?
The ulcers most often present fairly deep with well demarcated edges and even in shape. The wound beds initially are necrotic with minimal exudate and as they are debrided generally reveal a pale wound base. The surrounding tissue (periwound and lower leg) is often blanched, dry, shiny, and decreased in temperature.
How are arterial ulcers diagnosed?
Physical assessment should include both a general exam, looking for problems relating to lungs, heart and nervous system, and a focused exam of the affected extremities and arterial pulses. Vascular laboratory findings can also help confirm a diagnosis of arterial ischemic ulceration.
Why do venous ulcers hurt so bad?
When leg veins do not push blood back up to the heart as they should, the blood backs up (pools) creating extra pressure in the veins. If the condition is not treated, the increased pressure and excess fluid in the affected area can cause an open sore to form.
How do you manage arterial ulcers?
Treatment of arterial ulcers may involve surgical intervention for angioplasty, stenting, bypass grafting and, ultimately, amputation. Pain control is an important aspect of the management of arterial ulcers. Adequate analgesia is required to manage the severe ischaemic pain often experienced with arterial ulcers.
How do you dress an arterial ulcer?
Contrary to the management of other chronic wounds, arterial ulcers must be kept dry. Moist wound healing is not recommended for these types of ulcers. Excess moisture should be removed with absorbent dressings; however, the wound should be not so dry as to cause trauma to the wound bed during dressing changes.
How do you manage an arterial ulcer?
Do arterial ulcers heal?
Arterial leg ulcers (around 22% of ulcers) occur because of poor blood supply to the legs, when there is a block in a leg artery or narrowing of the arteries (atherosclerosis). Without treatment of the underlying poor arterial blood supply, ulcers take a long time to heal or may even never heal.
Should arterial ulcers be debrided?
It is not appropriate to debride arterial ulcers as this may promote further ischaemia and lead to the formation of a larger ulcer. Choice of wound dressings will be dictated by the nature of the wound.
What are the characteristics of an arterial leg ulcer?

What makes an arterial ulcer a chronic wound?
As cells die, the skin and tissues break down, leading to an ulcer (depressed wound). Once an arterial ulcer forms, the lack of blood flow to the area interferes with wound healing. Thus, arterial ulcers tend to be chronic, long-lasting wounds.
How is the ABI used to diagnose an arterial ulcer?
Ankle-brachial index (ABI) is used to measure peripheral tissue perfusion. When pulses are difficult to palpate, Doppler ultrasound can be used. Diagnosis of an arterial ulcer is made through a combination of the patient’s history, appearance and characteristics of the wound and the ABI results.
How to tell if you have a leg ulcer?
Arterial leg ulcers are often accompanied by severe cramping pain in the foot or calf muscle at rest when the legs are elevated. Pain may also increase when walking short distances (known as “intermittent claudication”).
