The authors present their statistical results in terms of maximum velocity and resistive Index of the inferior thyroid artery in a group of 200 patients, all with different diseases of the gland, but without hyperthyroidism. Measurements were taken in the first tract of the inferior thyroid artery, deep and posterior to the common carotid, without encountering any significant difficulties in 83% of cases, the determinations taking less than one minute; in some patients stretching or rotation of the neck was necessary in order to obtain a good result. The maximum systolic velocities were in agreement with those reported in the literature, but statistical analysis showed a significant correlation between systolic peak and certain groups or types of disease and, albeit less reliably, between the Resistive Index and type of disease. The section of the individual vessels showed no statistically significant variations. The results indicate a possible correlation between peak systolic velocity and Reistive Index in patients without hyperthyroidism, and therefore it may now be useful to study the relationship between these two parameters also in patients with normal serum levels of thyroid hormones.
