Diagnostic value of two-dimensional Doppler echography in structural and functional changes of the great arteries.

The paper discusses diagnostic possibilities of two-dimensional Doppler echography in ambulatory conditions in evaluating affection of the great arteries in patients with documented lesions of the vascular bed. The application of the given method substantially extends and complements information offered by routine clinical examination, and its informative value approximates that of the invasive examination methods. It makes possible visualization of the carotid, femoral and renal artery, measurement of their diameter, and quantitative assessment of the linear and volume velocity of blood flow. It proved particularly successful in diagnosing stenotic changes on the renal arteries, where it showed high specificity and sensitivity.
