[Ultrasonic arteriography of the carotid arteries (Doppler scanning). Comparison study with invasive arteriography]. / Artériographie ultrasonique des artères carotidiennes (Doppler scanning). Etude comparative avec l'artériographie invasive.

This work describes the performance of ultrasonic arteriography using the Doppler scanning technique. Results are compared with those of contrast arteriography in a group of 120 carotid arteries; specificity is very high (94%) but sensitivity is found to be rather low (62%); however, the number of highly abnormal cases is limited in this study, which does not permit to come to a representative figure for sensitivity. This method is totally non invasive, simple also for non highly trained paramedical staff and much cheaper than the Duplex scanning. Association with oculoplethysmography increases performance reaching up to 95.5% of correct results.
