Deep vein thrombosis (DVT) occurs when a blood clot forms in a deep vein in the leg or arm. This can be life threatening. which clots are more likely to produce a clinically significant pulmonary embolism ? Although this can occur in any venous system, the predominant clinical events occur in the vessels of the leg, giving rise to deep vein thrombosis, or in the lungs, resulting in a pulmonary embolus (PE). About 10-20% of thromboses extend proximally, and a further 1-5% go on to develop fatal pulmonary embolism. Suspected deep venous thrombosis (DVT) is: the most common reason for the clinical evaluation of the extremity veins. Pathophysiology: Damage to the valves in the vein causes blood to move back.
