Answer to previous blog:

See my blog at:
http://ultrasound-images.blogspot.in/2012/05/left-lower-limb-venous-doppler-study.html
The answer to that quiz is: it is a case of incompetence of the saphenofemoral junction with incompetence of multiple valves of the great saphenous vein resulting in varices in the left leg. These varicose veins are associated with incompetent and distended perforator veins in that area. This is well demonstrated in the color Doppler  images and videos posted on that blog.
