The GSV, a superficial vein, is the longest vein in the body. It has its origin in the dorsal venous arch of the foot, a superficial vein which connects the small saphenous vein with the GSV. It travels up the leg and medial side of the thigh to reach the groin, where it drains into the common femoral vein. [32]
focuses primarily on femoral and popliteal vein, Doppler ultrasonography showing absence of flow and hyperechogenic content in deep vein thrombosis of the subsartorial vein . Coronal plane, seen from medial side of lower leg, showing thrombosis of the fibular veins , with hyperechoic content and only marginal blood flow.
Deep vein thrombosis (DVT) is the formation of a blood clot within a deep vein. It most commonly affects leg veins, such as the femoral vein. Three factors are important in the formation of a blood clot within a deep vein—these are: the rate of blood flow, the thickness of the blood and; qualities of the vessel wall.
An ultrasound with a blood clot visible in the left common femoral vein. (The common femoral vein is distal to the external iliac vein.) Doppler ultrasonography showing absence of flow and hyperechogenic content in a clotted femoral vein (labeled subsartorial [ h ] ) distal to the branching point of the deep femoral vein .
Venous thrombosis is the blockage of a vein caused by a thrombus (blood clot). A common form of venous thrombosis is deep vein thrombosis (DVT), when a blood clot forms in the deep veins. If a thrombus breaks off and flows to the lungs to lodge there, it becomes a pulmonary embolism (PE), a blood clot in the
Small blood clots—say, dime- or nickel-sized on your heaviest flow days—may appear during menstruation and that’s not uncommon, especially if you feel fine otherwise and you’re not ...
The vein can be identified near the saphenous ostium by a typical ultrasonographic image the so-called Mickey mouse sign (the 2 ears will be the GSV and the ASV, the head is the common femoral vein). When the ultrasonography is performed, we can see it running across the anterior face of the thigh in a plan outside the femoral vessels, the GSV ...
Venous refill with dependency (should be less than 30 seconds) – the vein should bulge outward within 30 seconds of elevation for one minute. Buerger's test (assessment of arterial sufficiency): With the patient supine, note the colour of the feet soles. They should be pink. Then elevate both legs to 45 degrees for more than 1 minute.
