Popis: In the specialized literature, there is a low degree of information regarding the morphometric aspects of the inferior thyroid artery. The study was performed on CTAs, and the following was observed: the distance between the origin of the inferior thyroid artery in relation to the origin of the corresponding subclavian artery, as well as the artery diameter comparing right to left, according to gender and in comparison with the diameter of the subclavicular artery or thyrocervical trunk from which it originated.The study was performed on a total of 108 inferior thyroid arteries (64 on the right side and 44 on the left side, 48 in males subjects and 60 arteries in female subjects), analyzed on computed tomography angiography. Of the 108 arteries, the origin of the inferior thyroid directly from the subclavian artery was found in 34 cases, 20 cases being on the right side and 14 cases on the left side. In the other 74 cases, the origin of the inferior thyroid artery was in a thyrocervical trunk, 44 cases being on the right side, and 30 cases on the left side. The distance and mean diameters are variable between genders and the left/right side.The inferior thyroid artery is one of the arteries most susceptible to variations in terms of origin and size. With differences between the two sides (right and left), as well as differences related to gender.
