Ultrasound Scan:
Arm Arterial Doppler

Arm artery disease, also known as peripheral artery disease (PAD) affecting the upper extremities, refers to the narrowing or blockage of the arteries that supply blood to the arms. It is a form of atherosclerosis, a condition characterised by the buildup of fatty deposits (plaques) within the arterial walls, leading to reduced blood flow to the affected area. Arm artery disease is similar to the more common form of PAD that affects the arteries of the lower extremities (legs and feet). However, arm artery disease is less prevalent and often receives less attention compared to lower extremity PAD. The narrowing or blockage of the arm arteries can lead to various symptoms, including:

 

Arm pain or discomfort

Individuals with arm artery disease may experience pain, aching, or cramping in the arm muscles, particularly during physical activity. This is known as claudication and is typically relieved with rest.

 

Weakness or fatigue

Reduced blood flow to the arm muscles can result in weakness or fatigue, especially with repetitive arm movements or prolonged use. The affected arm may feel heavy or difficult to lift.

 

Coldness or numbness

Insufficient blood flow can lead to sensations of coldness or numbness in the arm, hand, or fingers. The affected extremity may feel cooler to the touch compared to the unaffected arm.

 

Changes in skin colour or texture

Arm artery disease can cause changes in the colour or texture of the skin in the affected arm. The skin may appear pale, bluish (cyanotic), or have a shiny or waxy appearance.

 

Slow or weak pulses

When the arteries in the arm are narrowed or blocked, the pulses in the affected arm may become weak or difficult to detect.

 

Wounds or ulcers

In severe cases of arm artery disease, chronic poor blood flow can result in the development of non-healing wounds or ulcers on the fingers, hand, or arm.

This scan usually takes between 15-20 minutes to complete.

An Arm Arterial Doppler study involves the arteries in your upper and lower arm to assess the blood flow to your hands. This ultrasound requires direct contact with your skin. We will require you to remove any jackets and jumpers.

We will ask you to lie on your back on our examination bed. During the scan we will apply gel to your arm and use the ultrasound machine to look at the arteries. You will hear noises from the ultrasound machine; this is all normal and is the sound of the blood flow moving through your arteries.

An arm artery ultrasound, also known as an upper extremity arterial ultrasound or arterial Doppler ultrasound, is performed to assess the blood flow and detect any abnormalities in the arteries of the arm. It is a non-invasive imaging test that uses high-frequency sound waves to create real-time images of the arteries. The ultrasound can provide information about the size, shape, and blood flow characteristics of the arm arteries. The results of the arm artery ultrasound can help guide treatment decisions, monitor disease progression, and evaluate the effectiveness of interventionsThe arm artery ultrasound is typically done to evaluate various conditions and concerns, including:

 

Peripheral Artery Disease (PAD)

The ultrasound can help diagnose and assess the severity of peripheral artery disease, which is characterised by narrowing or blockages in the arteries of the limbs, including the arms. It allows for the visualisation of the arm arteries to detect any significant stenosis (narrowing) or occlusions.

 

Arterial Occlusions or Emboli

An arm artery ultrasound can help identify the presence and location of arterial occlusions or emboli, which are blockages caused by blood clots or other debris. This information is valuable for determining appropriate treatment options.

 

Arterial Stenosis

The ultrasound can detect and quantify the degree of stenosis (narrowing) in the arm arteries. This is important for assessing blood flow limitations and determining the need for interventions such as angioplasty or stenting.

 

Assessment of Grafts and Fistulas

In individuals who have undergone arterial bypass surgery or have an arteriovenous fistula (used for dialysis access), the arm artery ultrasound can evaluate the functioning and patency of these grafts or fistulas.

 

Evaluation of Arm Pain or Weakness

If an individual experiences arm pain, weakness, or other symptoms related to reduced blood flow in the arm, an ultrasound can be performed to assess the blood vessels and identify any underlying arterial abnormalities.

The development of arm artery disease, also known as peripheral artery disease (PAD) affecting the upper extremities, can be influenced by several risk factors. These risk factors can increase the likelihood of developing the condition. The common risk factors for arm artery disease include:

 

Smoking

Smoking is one of the most significant risk factors for arm artery disease. The chemicals in tobacco smoke can damage the lining of the blood vessels, leading to inflammation and narrowing of the arteries.

 

Age

The risk of developing arm artery disease increases with age. The condition is more common in individuals over 50 years old, and the risk continues to rise with advancing age.

 

Diabetes

People with diabetes are at a higher risk of developing arm artery disease. High blood sugar levels can contribute to the development of atherosclerosis (plaque buildup) in the arteries, leading to reduced blood flow to the arms.

 

High blood pressure

Hypertension (high blood pressure) puts additional stress on the arterial walls, increasing the risk of developing arm artery disease. Uncontrolled high blood pressure can accelerate the progression of atherosclerosis.

​

High cholesterol levels

Elevated levels of LDL cholesterol ("bad" cholesterol) and triglycerides, along with low levels of HDL cholesterol ("good" cholesterol), contribute to the development of atherosclerosis and increase the risk of arm artery disease.

 

Obesity or overweight

Excess body weight can contribute to various risk factors for arm artery disease, such as diabetes, high blood pressure, and high cholesterol levels.

 

Family history

Individuals with a family history of arm artery disease or other cardiovascular conditions have an increased risk of developing the condition themselves. There may be genetic factors that predispose certain individuals to the development of arterial disease.

 

Sedentary lifestyle

Lack of regular physical activity and a sedentary lifestyle can increase the risk of arm artery disease. Physical activity promotes healthy blood flow and helps maintain the health of the blood vessels.

 

Other medical conditions

Certain medical conditions, such as chronic kidney disease, rheumatoid arthritis, and lupus, are associated with an increased risk of developing arm artery disease.

Arm artery disease, also known as peripheral artery disease (PAD) affecting the upper extremities, is characterised by the narrowing or blockage of the arteries that supply blood to the arms. The symptoms of arm artery disease can vary depending on the severity of the condition and the degree of blood flow restriction. Common symptoms include:

 

Arm pain or discomfort

Individuals with arm artery disease may experience pain, aching, or cramping in the arm muscles, particularly during physical activity. The pain typically occurs in the affected arm and may subside with rest.

 

Weakness or fatigue

Reduced blood flow to the arm muscles can result in weakness or fatigue, especially with repetitive arm movements or prolonged use. The affected arm may feel heavy or difficult to lift.

 

Coldness or numbness

Reduced blood flow can lead to sensations of coldness or numbness in the arm, hand, or fingers. The affected extremity may feel cooler to the touch compared to the unaffected arm.

 

Changes in skin colour or texture

Arm artery disease can cause changes in the colour or texture of the skin in the affected arm. The skin may appear pale, bluish (cyanotic), or have a shiny or waxy appearance.

 

Slow or weak pulses

When the arteries in the arm are narrowed or blocked, the pulses in the affected arm may become weak or difficult to detect.

 

Wounds or ulcers

In severe cases of arm artery disease, chronic poor blood flow can result in the development of non-healing wounds or ulcers on the fingers, hand, or arm.

 

It's important to note that some individuals with arm artery disease may be asymptomatic, especially in the early stages of the condition. However, as the disease progresses, symptoms are more likely to manifest.

The treatment for arm artery disease, also known as peripheral artery disease (PAD) affecting the upper extremities, aims to improve blood flow, relieve symptoms, and prevent complications. The specific treatment options depend on the severity of the disease, the presence of symptoms, and the individual's overall health. Treatment approaches for arm artery disease may include:

 

Lifestyle modifications: Making certain lifestyle changes can significantly improve arm artery disease. These may include:

• Smoking cessation: Quitting smoking is crucial, as it is a major risk factor for the progression of arterial disease. Smoking cessation can help slow the disease progression and reduce symptoms.

• Regular exercise: Engaging in regular physical activity, under the guidance of a healthcare professional, can improve circulation and promote overall cardiovascular health.

• Healthy diet: Adopting a well-balanced diet that is low in saturated and trans fats and rich in fruits, vegetables, whole grains, and lean proteins can contribute to improved arterial health.

• Weight management: Maintaining a healthy weight helps reduce stress on the arteries and improves overall cardiovascular health.

• Blood pressure and cholesterol management: Controlling blood pressure and managing cholesterol levels through medication, if necessary, can help slow the progression of arm artery disease.

 

Medications: Medications may be prescribed to manage symptoms, control risk factors, and prevent complications associated with arm artery disease. These may include:

• Antiplatelet agents: Medications such as aspirin or clopidogrel may be prescribed to reduce the risk of blood clot formation and improve blood flow.

• Cholesterol-lowering medications: Statins or other lipid-lowering medications may be prescribed to control cholesterol levels and slow the progression of arterial disease.

• Blood pressure medications: Medications to control high blood pressure, such as angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs), may be prescribed to help manage arterial disease.

​

Interventional procedures: In some cases, when lifestyle modifications and medications are insufficient or the disease is severe, interventional procedures may be necessary. These procedures are aimed at restoring blood flow to the affected arm arteries and may include:

• Angioplasty and stenting: During an angioplasty, a thin tube (catheter) with a balloon at its tip is inserted into the narrowed artery. The balloon is inflated to widen the artery, and a stent may be placed to help keep it open.

• Bypass surgery: In cases of severe artery blockage, a surgical bypass procedure may be performed to create a new pathway for blood flow using a graft.

 

Wound care: For individuals with non-healing wounds or ulcers related to severe arm artery disease, proper wound care and management are essential to prevent infection and promote healing.

 

Rehabilitation and exercise programs: Participating in supervised exercise programs and rehabilitation can help improve symptoms, functional capacity, and overall quality of life.

 

The treatment approach for arm artery disease should be individualised based on the specific circumstances of each patient. It is important to consult with a healthcare professional for a comprehensive evaluation, diagnosis, and development of an appropriate treatment plan. Regular follow-up visits are essential to monitor progress, manage risk factors, and adjust treatment as needed.
