    Why is a duplex scanning of the veins of the lower extremities necessary?

    Ultrasound duplex scanning of the veins of the lower extremities is one of the best methods for diagnosing problems of varicose veins or thrombosis.

    Using this method, it is possible to assess not only the quality of blood flow, but also to diagnose the state of blood vessels, their walls and geometry.

    When can this study be ordered:

    • Aneurysms (stretching or thinning of the vessel wall).
    • Atherosclerosis (deposition of fat and calcium on the vascular walls).
    • Deep vein thrombosis (the formation of blood clots in the vessels).
    • Varicose veins (pathological expansion and deformation of blood vessels)
    • Post-thrombotic syndrome (after removal of blood clots, health care)

    Is thrombosis?

    Let’s dwell on one of the pathologies – thrombosis.

    This is a very dangerous disease, because the separation of a blood clot can lead to death or a significant deterioration in health.

    Thrombus is an intravital blood clot that forms in blood vessels, it consists of fibrin and blood cells. It is formed as a result of pathological changes in the walls of blood vessels or changes in the properties of blood.

    Causes of blood clots

    There are three main factors for thrombosis:

    1. Damage to the vessel wall (as a result of injury, during operations and improper nutrition (cholesterol plaques are formed), infections, when lifting weights, childbirth, etc.).
    2. Blood clotting disorders (tendency to increased coagulability). Changes in blood clotting can occur due to metabolic disorders or hormonal imbalances.
    3. Stagnation of blood. This happens when a person stays in one position for a long time (for example, at a computer, in an airplane chair, or in bed).

    Modern methods of lower limb vascular bridging make it possible to accurately assess the presence and condition of blood clots. When diagnosing a thrombus in the leg (scanning a vein), the doctor lightly presses on the muscle tissue, which transfers the load to the vessels. If there is no thrombus, the lumen of the vein will decrease as much as possible; if there is, it will remain unchanged.

    Here are some examples.

    Norm:

    “Valves are visualized as fine structures. The great saphenous vein in the area of the sapheno-femoral junction closes completely during compression, the walls are 0.74 mm thick, no pathological inclusions were found in the lumen. ”

    Thrombosis:

    “On the border of the upper and middle third of the left thigh in the lumen of the great saphenous vein, a heterogeneous structure of moderately increased echogenicity of the tissue (thrombus) is visualized. BPV diameter up to 7.15mm, when compressed it is compressed to 4.45-5.89mm. ”

    Why is a duplex scanning of the veins of the lower extremities necessary?

    With ultrasound of the veins of the lower extremities, the state of blood flow can be seen.

    “The large saphenous vein on the left with a diameter of 7.89 mm, the lumen is visualized by an echogenic mass of a heterogeneous structure (thrombus), it is not subjected to compression. At CFM, the color flow is visualized in small single fragments. ”

    Why is a duplex scanning of the veins of the lower extremities necessary?

    As you can see, everything is visualized very clearly. Therefore, at the consultation of an ultrasound doctor after undergoing Doppler ultrasonography, you will receive a clear picture of the health of your blood vessels and will be able to prevent significant health problems.
