[High resolution vascular ultrasonography. Personal experience]. / L'ecotomografia vascolare ad alta risoluzione. La nostra esperienza.

Personal experience in the use of two-dimensional echography (B-scan) in vascular diagnosis is reported, stress being laid on its advantages with respect to other non-invasive investigations (rheography, photoplethysmography, Doppler measurement) and conventional arteriography. The importance of the technique is considered and special attention paid to the system of Biosound for defining small and initial parietal changes whose consequences, particularly if located in the carotid district, can be very serious. The result of an 18-month study using real-time Doppler ultrasonography is reported. 147 carotids and 88 lower extremities were involved and percentages were matched against conventional arteriography where the latter was carried out.
