THE PARTICIPATION OF THE SUPERIOR AND INFERIOR THYROID ARTERIES IN THE VASCULARIZATION OF THE THYROID GLAND
Abstract
Background and aim: This study aims to evaluate the level of vascularization within the thyroid gland by analyzing the diameters of the Romanian population’s superior and inferior thyroid arteries. Materials and methods: Our study was performed on angiographies by computed tomography on a LightSpeed VCT64 Slice CT on 317 thyroid arteries, 168 arteries on the right side, and 149 on the left side. The measurements of the diameters of the superior and inferior thyroid arteries were compared between sides (left/right) and sexes. Results: The diameter of the superior thyroid artery, right and left, we’re observed on a number of 176 cases, finding it to be between 1.6-4.3 mm. The right superior thyroid artery was between 1.8-4.3 mm in diameter while the left artery was between 1.6-2.8 mm in diameter. The diameter of the inferior thyroid artery, right and left, on a number of 141 cases was found to be between 1.2-4.1 mm, the right one was between 1.7-3.9 mm and the left was between 1.2-4.1 mm. Conclusions: The variances in the diameters of the two arteries result in fluctuation in their respective contributions to the vascular supply of the thyroid gland.
