Vascular Lab Studies uses doppler, ultrasound, and sound waves to diagnose vascular disease in a non-invasive manner.
Peripheral Vascular Disease (PVD)
PVD is a build-up of plaque in the arteries outside your heart that reduces the flow of blood. As a result, some parts of your body do not get the oxygen they need. People with PVD are three to four times more likely to die from stroke or heart attack than people of the same age who do not have PVD.
Symptoms include:
Tests to diagnose this condition include:
Ankle Brachial Index (ABI) – This is a simple non-invasive test that measures the ratio of the blood pressure in your ankle to that in your arm by placing blood pressure cuffs on the arms and lower legs. This ratio may indicate a potential vascular problem.
Ultrasound Duplex Test – This is a non invasive test using sound waves to provide an image of the inside of the blood vessel to determine if a specific artery has plaque build up. There is no radiation used and generally no discomfort from the application of the ultrasound transducer to the skin.
Deep Vein Thrombosis (DVT)
DVT is a blood clot that develops in a vein deep in the body. The clot may partially or completely block blood flow through the vein. Most DVTs occur in the lower leg, thigh or pelvis, although they also can occur in other part of the body including the arm, brain, intestines, liver, or kidney.
DVT most commonly occurs in just one leg or arm. Not everyone with DVT will experience symptoms, although when present, they may include:
Duplex Venous Ultrasound – This test is used to evaluate the blood flow in the veins and to detect the presence and specific location of blood clots. A technologist applies pressure when scanning your arm or leg. If the vein does not compress with pressure, it may indicate a blood clot is present.
Carotid Artery Disease
Carotid Artery Disease is the build-up of plaque on the inside of the carotid arteries. The carotid arteries carry oxygen-rich blood away from the heart to the head and body. Over time, the build-up narrows the artery, decreasing blood flow to the brain which can lead to a stroke.
There may not be any symptoms of carotid artery disease. A transient ischemic attack (also called TIA or “mini-stroke”) is one of the most important warning signs of a stroke. A TIA is a temporary episode of:
Carotid Duplex Ultrasound – A procedure that uses high-frequency sound waves to view the blood vessels in the neck to determine the presence of narrowing in the carotid arteries.
Computerized Tomography (CT Scan) – A CT of the brain may be performed if there is a possibility a stroke has already occurred. This test will reveal areas of damage on the brain.
Abdominal Aortic Aneurysm (AAA)
An Abdominal Aortic Aneurysm is a dilation of a segment of the aorta, the main artery through the trunk of the body.
An AAA can be detected by using ultrasound imaging which provides an accurate, safe, and non-invasive means to measure the aortic size. The most important risk factors for AAA include:
Renal Artery Disease
The renal arteries provide blood flow to the kidneys and can become diseased which results in reduced blood flow to the kidneys. This reduced blood flow results in hypertension. Renal Artery Stenosis is the most common correctable cause of hypertension. Long-standing, untreated Renal Artery Disease is also an important cause of kidney failure.
Renal Artery Disease can be detected by using ultrasound imaging which is an accurate, non-invasive, and cost-effective method of diagnosing disease without using contrast material.
Preparing for Carotid, Arterial, and Venous Ultrasound Test
Take your prescribed morning medications; including your heart and/or blood pressure medications.
Wear comfortable clothing. If having a Carotid ultrasound, make sure to wear a shirt that is loose fitting around the neck.
Leave all jewelry, valuables and money at home.
Preparing for Abdominal Ultrasound (Renal, Aorta and Iliac) Test
What to do the day before your vascular ultrasound test: Take an antigas medication, such as Gas-X, before going to bed. No food after midnight.
The day of your procedure: No food the morning of the testing. Take your prescribed morning medications with small sips of water. If you tak insulin or medicine for diabetes, wait and take after testing.
