WebThe hepatojugular reflux is a clinical test that can be used to help elucidate the JVP. The test involves applying firm pressure over the right upper quadrant of the abdomen for 10 seconds. During the manoeuvre the IJV should be observed. Compression increases venous return that causes a temporary rise in the JVP for 2-3 beats. WebReflux begins at the saphenofemoral junction (SFJ) and extends down the great saphenous vein (GSV) to the thigh. At this point the reflux spills into a varicose tributary (point A). The incompetent tributary then refills the GSV at a lower level (point B) and leads to an additional segmental incompetence of the GSV.
