hi my name is Shelly lower extremity deep Venus thrombosis is a potentially life-threatening condition so an accurate and timely diagnosis is crucial we can perform a quick compression study of the deep Venus system of the leg with the patient supine head slightly elevated if possible and the leg externally rotated I'm using the pal phased array linear scanner in the Venus preset and I'm going to start up nice and high in the patient groin and look for the common femoral vein so once we locate the vein I'm just going to compress it move down a little bit further until we locate the junction of the greater sopus vein and the common femoral vein compress there and continue to move down the leg performing compressions every couple of inches so still seeing superficial femoral vein in the center of the screen and compressing all the way down when we get to the adductor canal compression can be a little bit more challenging Sometimes using your hand on the other side of the patient works well and when we get to the distal thigh we can go to the posterior part of the knee and visualize the poal veins so I'm just going to compress here and again continue compressing until we get to the area of the trifurcation and at this point we can be satisfied that there's no evidence of deep Venus thrombosis
