Introduction to Common Vascular Diagnostic Tests 

Basic vascular tests can save your life when they find abnormalities in your heart and arteries. The tests are designed to detect common vascular diseases such as atherosclerosis, peripheral artery disease (PAD), and deep vein thrombosis (DVT). These are problems that lead to strokes, heart attacks, and other complications.

The tests, designed for particular conditions, can find clogged arteries and veins at the first sign of symptoms. They may locate potential problems in people with high blood pressure, high cholesterol, and irregular heartbeats before there are major symptoms.


Common Vascular Diseases

Atherosclerosis is the most common cause of heart attacks. Arteries are blocked with a buildup of plaque, fatty material and cholesterol deposits. Blood circulation becomes difficult and arteries receive less oxygen.  Atherosclerosis can be controlled if diagnosed before symptoms occur.

Peripheral artery disease or PAD is similar to atherosclerosis. The buildup of fatty substances and plaque on the walls of arteries limits blood flow to muscles in arms and legs.

Deep Vein Thrombosis or DVT is actually a blood clot in the veins of your legs. This clot can break free and travel to the lungs.

Varicose Veins are swollen, twisted veins usually occurring in the legs due to valve malfunctions.

Chronic Venous Insufficiency is when there is poor blood flow through the veins, often due to damaged valves, leading to swelling and skin changes.

Aneurysms are abnormal bulging or ballooning of a blood vessel wall, which can lead to rupture in the brain (brain aneurysm) or the aorta (aortic aneurysm).

Lymphedema is swelling due to lymphatic system blockages, causing fluid buildup in tissues, often in legs.

These conditions can be located through non-invasive tests using a variety of equipment to look inside your body.


Non-Invasive Tests

Duplex Ultrasound with Doppler is the most common non-invasive tool used to diagnose heart and artery conditions. This is the result of modern echo location technology that can look into various ares of your body.

The patient can have an ultrasound at any age, although it is usually recommended for adults who may be susceptible to heart disease. This includes elderly people, individuals with diabetes and obesity issues, and smokers. Even healthy people can have an ultrasound to monitor their heart as they age.

Te device also uses sound waves to visualize blood flow in the veins. It helps detect varicose veins and other venous diseases by showing any abnormal blood flow or blockages. This effective diagnostic tool allows doctors to assess the severity of the condition and plan appropriate treatment.

Ultrasound is also used on other parts of the body as well to detect problems such as cancer growth in different areas. Moreover, it is used on pregnant women to determine the health of the growing baby.

The patient lies comfortably on a table while the technician guides a small camera over the surface of the area to be checked. Patients may be able to watch their heartbeat and blood flow during this test. The Doppler technology adds color and high definition to the screen for the best pictures of the heart, arteries, legs, thyroid, and more.

Computerized Tomography or a CT angiography scan uses X-ray technology to give a thorough view of the body. The CT scan is used extensively to diagnose various conditions, including heart disease. The patient lies on a table while the machine take photos of the problem areas. It is generally non-invasive.

The Ankle Brachial Index (ABI) test is a quick way to check for peripheral artery disease. This test checks the blood flow in legs and arms to determine any blockage.


Other Imaging Tests

Magnetic Resonance Angiography is also used to check blood vessels. Radio waves and a magnetic field are used to find abnormal conditions in the heart and arteries. The exam does not use radiation. The doctor may inject a contrast material into your blood stream to follow blood flow.

Digital subtraction angiography (DSA) is an invasive treatment that is used for assessing aneurysms. It may be used in place of a CTA scan in severe conditions.

Invasive Angiography is used to check for blocks in coronary arteries. A contrast dye is injected into the bloodstream and followed on an x-ray machine. This standard test is used to measure blood flow through the heart to find any blockage.
