[Phlebologic indications for duplex sonography].

Duplex ultrasonography has all the features required considerably to enrich the angiological-phlebological diagnostic work-up in the doctor's office. It is a harmless, noninvasive, functional and morphological examination technique that is available at any time. Major application possibilities are to be seen in the diagnosis of deep vein thrombosis, in the differentiated evaluation of insufficiency of the major vein, in the direct representation of insufficient perforating veins, and, in particular, for providing highly informative monitoring of the success of therapeutic measures. At the present time, however, points that militate against its use in the doctor's office are the high price of the equipment, and the requirements for further training, which are difficult to meet in the case of practising physicians.
