title: [Venous ultrasonography of the lower limbs in the diagnosis of thrombosis. Examination methodology and presentation of results].
abstract: Two criticisms are levelled against venous ultrasonography: its operator-dependent nature and the absence of any overall imaging document which can serve as a reference and be read by all. A very precise investigation technique is suggested to deal with the first criticism. This describes the investigation in detail, level by level from the inferior vena cava to the lower third of the leg and indicates the optimal position of patient and operator, in particular concerning the leg. A method of imaging presentation is proposed to deal with the second criticism. The site and extent of venous thromboses are shown on a precise anatomical diagram including muscle veins. This diagram reproduced by reduction on a four-fold card is given to the patient to be used during subsequent follow-up. It can be used as a reference document in case of suspected extension or recurrence. Ultrasonography has several advantages over phlebography: a better reliability rate, better sensitivity for lesions in muscles and where there are twin veins, possibilities of differential diagnosis of DVT and of the discovery of concomitant pathology. It should now always be performed as the investigation of primary intention.
