Deep vein thrombosis. Coloured X-ray of a patient's lower leg showing deep vein thrombosis. The patient has been injected with an X-ray-opaque substance,making blood vessels show lighter. The large bone at left is the tibia; at right is the smaller fibula. A fresh clot (thrombus) has formed in the lower centre,where the blood vessels look concentrated. This has blocked a vein,preventing normal blood flow in the leg. Normal blood vessels reappear at the top. Deep vein thrombosis is blood clot formation in deep-lying veins. It is dangerous if the clot is large,as fragments may break off and block vital arteries elsewhere | |
