  2. Ultrasonography of chronic venous insufficiency of the legs

    en.wikipedia.org/wiki/Ultrasonography_of_chronic...

    Doppler measurements which trace the echoes of the generated soundwaves received by the probe, enable the direction and velocity of the blood flow to be depicted. The overlay of color onto the Doppler information lets these images be seen more clearly. [8] The choice of a probe will depend on the depth needed to be studied.

    The ABPI test is a popular tool for the non-invasive assessment of Peripheral vascular disease (PVD). Studies have shown the sensitivity of ABPI is 90% with a corresponding 98% specificity for detecting hemodynamically significant (stenosis of more than 50%) in major leg arteries, defined by angiogram. [3] However, ABPI has known issues:

  4. Buerger's test - Wikipedia

    en.wikipedia.org/wiki/Buerger's_test

    Buerger's test is performed in an assessment of arterial sufficiency. It is named after Leo Buerger . The vascular angle , which is also called Buerger's angle , is the angle to which the leg has to be raised before it becomes pale, whilst lying down .

    Absence of the portal system in a first trimester case associated with hygroma and aorto-umbilical fistula. (A): Transverse plane of the upper abdomen with color Doppler applied, showing umbilical cord insertion, stomach, the prominent hepatic artery and no afferent liver venous perfusion; (B): midsagittal plane reconstructed from a three-dimensional volume acquisition were the crown-rump ...

  6. Chronic venous insufficiency - Wikipedia

    en.wikipedia.org/wiki/Chronic_venous_insufficiency

    Chronic venous insufficiency (CVI) is a medical condition characterized by blood pooling in the veins, leading to increased pressure and strain on the vein walls. [1] The most common cause of CVI is superficial venous reflux, which often results in the formation of varicose veins, a treatable condition. [2]

    Coronal plane, seen from medial side of lower leg, showing thrombosis of the fibular veins, with hyperechoic content and only marginal blood flow. Ultrasonography in suspected deep vein thrombosis focuses primarily on the femoral vein and the popliteal vein , because thrombi in these veins are associated with the greatest risk of harmful ...

  9. Telangiectasia - Wikipedia

    en.wikipedia.org/wiki/Telangiectasia

    Before any treatment of leg telangiectasia is considered, it is essential to have duplex ultrasonography, the test that has replaced Doppler ultrasound. The reason for this is that there is a clear association between leg telangiectasia and underlying venous reflux. [12]
