ABSTRACT
Dynamic ultrasonography is a diagnostic ultrasound examination which makes possible non-invasive visualization of soft tissue structures of the neck and its large blood vessels. Duplex ultrasonography makes moreover aimed assessment of the blood flow in major vessels possible and thus supplements in a significant way the echotomographic picture. Because of its non-invasive character it is preferable to CT and angiography in diagnostic work.

Duplex sonography not only provides the ENT specialist with valuable information on topographic relations of soft tissue tumours with the main blood vessels of the neck but provides also information on the blood flow in these vessels. It makes it possible to draw reliable conclusions on vascular anomalies or dislocation of the vessels, on affections of the vascular wall, on restricted patency of vessels due to the action of a tumour (compression, penetration) or inflammation (thrombus) or changes in the flow through the jugular vein conditioned by impaired passage in the S-shaped sinus. In some instance ultrasonic examination is a valuable method for evaluation of the dynamic and further development of the basic disease and can replace classical arteriography or phlebography.

PIP: The chemical affinity of chlormadinone acetate with Superlutinem (used in Antigest and Antigest-B) and with Chlorsuperlutinem (a component of Biogest) in connection with the generation of cancer by hormanal contraceptives is discussed. Undesirable effects were found to be more prevalent with progestagen components than with estrogens. Cases of jaundice, hepatitis, hypertension, and thrombophlebitis with the use of oral contraceptives were found to be more frequent in cases of use of 1 year or more. The connection of the failure of hormonal contraceptives with certain sedatives is discussed.^ieng
