Venous Duplex Scans are specialized ultrasounds that examine the veins. In this procedure, you are evaluated for symptoms such as leg pain or swelling, leg heaviness, excessive varicose veins, leg discoloration, shortness of breath, or suspected blood clots in your legs.
What Is The Purpose Of Venous Duplex Ultrasound?
Tests like this help you determine how your veins are carrying blood. A vein duplex scan can be used to detect blood clots in leg veins and to evaluate for abnormal veins that cause varicose veins.
What Does A Duplex Ultrasound Show?
Using duplex ultrasound, you can see how blood flows through your vessels and determine the speed at which blood flows through them, as well as the diameter of the vessel and the amount of obstruction there is. The sound waves used in conventional ultrasound are painless.
How Is The Duplex Ultrasound Performed?
Using high-frequency sound waves, Duplex ultrasound can be used to study the speed of blood flow and the structure of the leg veins. Doppler and B-mode ultrasound are the two modes of ultrasound that are used induplex. Using a B-mode transducer (like a microphone), the vessel being studied can be viewed in detail.
What Happens During A Duplex Scan?
The provider uses two transducers when using a duplex scan. A second one (Doppler) allows your provider to hear the sound waves that the transducer sends. Hearing how fast blood flows through a blood vessel and in which direction it is flowing is an indication of how fast blood is flowing through a blood vessel.
What Is The Difference Between Duplex Ultrasound And Doppler Ultrasound?
A Doppler study is a non-invasive study of the blood vessels and heart that uses ultrasonography. A Duplex study is a more invasive study of the blood vessels and heart. Ultrasound is used to provide high-frequency waves. Blood flow can be detected with duplex ultrasonography, which provides a colored image.
How Is Venous Duplex Ultrasound Done?
A lower venous duplex is performed on the legs and ankles to view the veins. jelly is placed on the area being examined, and a wand-like device called a transducer is passed lightly over the vein to examine it.
