Some of the diagnostic vascular tests that your physician may use are listed below:
Carotid duplex ultrasound
Duplex ultrasound combines traditional ultrasound with Doppler ultrasonography. Regular ultrasound uses sound waves that bounce off blood vessels to create pictures, while Doppler ultrasound records sound waves reflecting off moving objects, such as blood, to measure their speed and other aspects of flow.
Carotid duplex ultrasound uses high-energy sound waves to determine how well blood is flowing through the carotid arteries - the major blood vessels at the sides of the neck through which oxygen-rich blood flows to the brain. The test can be used to detect narrowing or blockages in these arteries (carotid artery disease). If blood flow through these arteries becomes significantly impaired, the patient has an increased risk of stroke.
Venous duplex ultrasound
This test is similar to carotid duplex ultrasound, except that the test is used to measure blood flow through the veins, usually in the legs. Venous duplex ultrasound may be used to diagnose disorders such as blood clots, varicose veins, and peripheral vascular disease.
Pulse volume recording (ankle brachial index/ABI measurement)
This test is usually done to check for narrowing or blockages of blood vessels in the arms or legs. Blood pressure cuffs are wrapped snugly around an arm and a leg. The healthcare provider inflates the cuffs, and a machine measures the pulses from each cuff. A decrease in the pulse between an arm and a leg may indicate a blockage. This test may be used to diagnose blood clots and peripheral vascular disease.
