The diagnosis of deep venous thrombosis of the lower limbs often poses difficult problems. Whilst it is usually obvious in cases of massive thrombosis of the ilio-femoral veins, it is often much more difficult in the presence of isolated minimal obstruction of a leg vein. Clinical findings are often inadequate, various laboratory investigations fail to provide definite arguments and only phlebography can confirm venous occlusion. Ultrasound examination by Doppler effect can offer great service in all cases by confirming the clinical impression and aiding in determining the indication for radiological investigation. The reliability of the examination is excellent above the knee and much more hazardous below. At any event, it is based upon a strict protocol and depends essentially upon the experience of the individual performing it.
下肢深静脉血栓形成的诊断常常带来难题。虽然在髂股静脉发生大量血栓形成的病例中通常很明显，但在存在孤立的小腿静脉轻度阻塞时往往要困难得多。临床发现常常不足，各种实验室检查无法提供确切依据，只有静脉造影才能证实静脉阻塞。通过多普勒效应进行的超声检查在所有病例中都能发挥很大作用，它能证实临床印象并有助于确定进行放射学检查的指征。该检查在膝盖以上的可靠性极佳，而在膝盖以下则风险大得多。无论如何，它基于严格的方案，并且本质上取决于进行检查的个人经验。
