Three (3) of these ulcer types are exclusively lower-extremity wounds located on the foot, ankle and lower leg: venous stasis ulcers, arterial ulcers, and diabetic neuropathic ulcers. Venous stasis ulcers, caused by venous insufficiency, account for approximately 75% of lower extremity ulcerations.

Are arterial ulcers stasis ulcers?

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 venous ulcers and stasis ulcers the same thing?

Venous ulcers, also referred to as stasis, insufficiency or varicose ulcers, are the result of malfunctioning venous valves causing pressure in the veins to increase. These typically occur along the medial or lateral distal (lower) leg.

What is an arterial ulcer?

Arterial wounds, also known as arterial ulcers, are painful injuries in your skin caused by poor circulation. ‌ Arterial ulcers typically happen when blood is unable to flow into the lower extremities, like the legs and feet.

What is stasis ulcers in medical terms?

A stasis ulcer is a breakdown of the skin (ulcer) caused by fluid build-up in the skin from poor vein function (venous insufficiency). Fluid leaks from the veins into skin tissue when the blood backs up rather than returning to the heart through the veins.

Are arterial ulcers pale?

In addition, the base color of the extremity may turn red when dangled and pale when elevated. An additional sign of an arterial ulcer is delayed capillary return in the affected extremity. These ulcers are generally very painful, especially while exercising, at rest, or during the night.

How can you tell the difference between arterial and venous ulcers?

In venous disease, ulcers are usually located in the gaiter area between the ankle and the calf, often on the medial aspect of the leg. Arterial leg ulcers occur as a result of reduced arterial blood flow and subsequent tissue perfusion.

What is the difference between arterial and venous insufficiency?

Venous insufficiency refers to a breakdown in the flow of blood in our veins, while arterial insufficiency stems from poor circulation in the arteries. Left untreated, both conditions may lead to slow-healing wounds on the leg.

What causes an arterial ulcer?

What causes arterial ulcers? Arterial ulcers are caused by arterial insufficiency; that is, inadequate delivery of oxygen and nutrient-rich blood to the tissues. Arterial insufficiency is caused by high blood pressure and narrowing of the arteries due to atherosclerosis.

What is the difference between venous and arterial ultrasound?

A venous ultrasound of the upper or lower extremities provides pictures of the veins and the blood flow within the veins of the arms or legs. An arterial ultrasound of the upper or lower extremities provides pictures of the arteries and the blood flow within the arteries of the arms or legs.

Are diabetic ulcers venous or arterial?

Typically, arterial ulcers are extremely painful. Venous ulcers can present with dull and achy pain in the entire leg, but the wound area itself usually doesn’t hurt unless it’s infected. Diabetic ulcers may present with the pins-and-needles pain or a loss of sensation that is associated with peripheral neuropathy.

Where are venous stasis ulcers located?

Commonly located on the ankle or calf, venous stasis ulcers are painful and red in color but may be covered with a yellow, fibrous tissue and an irregular border. Drainage and discharge are possible with venous stasis ulcers. This type of ulcer is common in patients with a history of leg swelling or varicose veins.

Why do venous stasis ulcers occur?

Venous ulcers typically occur because of damage to the valves inside the leg veins. These valves control the blood pressure inside the veins. They allow it to drop when you walk. If the blood pressure inside your leg veins doesn’t fall as you’re walking, the condition is called sustained venous hypertension.

How do you treat an arterial ulcer?

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 describe a venous stasis ulcer?

A venous stasis ulcer is wound on the skin. It is due to a pooling of blood in the veins. These ulcers happen most often on the legs. If left untreated, the ulcers can lead infection and other serious problems.

What should be included in the documentation of a venous stasis ulcer?

Document wound size, appearance, location, condition of surrounding skin, presence and characteristics of exudate, and signs and symptoms of infection.

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.

Do arterial ulcers have exudate?

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.

What is difference between PAD and PVD?

Peripheral artery disease (PAD) is the name of one specific disease, a condition that affects only arteries, and primarily the arteries of the legs. Peripheral vascular disease (PVD) is a generic “umbrella term” that describes a large number of circulatory diseases.

Do you stage stasis ulcers?

Venous stasis ulcers are the end stage of chronic venous insufficiency. In order to treat venous stasis ulceration, one must have a clear understanding of the pathophysiology of venous disease. Most of the vein problems that occur are due to increased pressure in the venous system.

Why is compression not used in arterial ulceration?

With an ABPI >1.3, compression should be avoided because high ABPI values may be due to calcified and incompressible arteries. In such patients, a specialist vascular assessment should be sought. That compression therapy is the mainstay of management of leg ulcer is beyond doubt.

Are ischemic ulcers painful?

Wound may or may not be painful. Skin on the leg appears shiny, tight, dry, and hairless. Dangling the leg down off the side of a bed or chair causes the leg to turn red. When you raise the leg, it turns pale and cool to touch.

Are arterial ulcers painful?

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.

Can you Debride an arterial ulcer?

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. Vasoconstrictive drugs such as non-selective β blockers should be avoided.

What are the different types of leg ulcers?

• Venous stasis ulcers.
• Neurotrophic (diabetic)
• Arterial (ischemic ulcers)

What are the signs and symptoms of arterial insufficiency?

• Painful cramping in one or both of your hips, thighs or calf muscles after certain activities, such as walking or climbing stairs.
• Leg numbness or weakness.
• Coldness in your lower leg or foot, especially when compared with the other side.
• Sores on your toes, feet or legs that won’t heal.

What is chronic arterial insufficiency?

Chronic arterial insufficiency (CAI) is a common condition affecting predominantly older patients. It normally involves the lower limbs and is usually due to progressive furring up and hardening of the arteries due to atherosclerosis.

What is the difference between a blood vessel and an artery?

‌Arteries and veins (also called blood vessels) are tubes of muscle that your blood flows through. Arteries carry blood away from the heart to the rest of the body. Veins push blood back to your heart. You have a complex system of connecting veins and arteries throughout your body.

What are the symptoms of a blocked artery in your leg?

• Painful cramping in one or both of your hips, thighs, or calf muscles after doing physical activities, such as walking or climbing stairs.
• Prolonged soreness on your feet, legs, and toes that don’t heal or are very slow to heal.
• Discoloration of legs.

What does arterial ultrasound show?

Ultrasound is a procedure that uses sound waves to “see” inside your body. An arterial duplex ultrasound uses sound waves to create a color map of the arteries in your legs to identify: Narrowing of your vessels that may be causing leg pain when walking. Resting leg pain.

What type of ulcer is diabetic foot?

What Is a Diabetic Foot Ulcer? A diabetic foot ulcer is an open sore or wound that occurs in approximately 15 percent of patients with diabetes, and is commonly located on the bottom of the foot. Of those who develop a foot ulcer, six percent will be hospitalized due to infection or other ulcer-related complication.
