This animation contains sound. Superficial thrombophlebitis occurs if a superficial
vein becomes inflamed and a blood clot forms. This is usually in the superficial veins of
the leg. Unlike deep vein thrombosis, which occurs in deep veins, this condition is usually much less serious. Here we show the position of the superficial
veins of the leg. The superficial veins branch throughout the
leg and lie just under the skin. They pass blood back into the deep veins. The blood then flows back up towards the heart. The inflammation and blood clot can occur
in any part of the superficial veins in the leg. It’s most common in the long vein called the
saphenous vein which runs along the inner leg from your hip to your
foot. Inflammation occurs if a vein is damaged, if the flow of blood in the vein slows down
or stops, or if the blood has a higher than normal tendency
to clot. The inflammation and blood clot may cause
pain and swelling in the affected leg. But this will usually get better after about
two to six weeks. This is the end of the animation. Click on the animation screen to watch it
