“…Tsegay et al [ 12 ] performed a cadaveric study in 2019 and observed that, the ECA was identified as the most frequent location of STA origin. The TCT gave rise to the ITA in each case, while in the present study the result for STA corresponds with the given study as in majority of cases the STA arises from ECA on both the sides, whereas in the case of ITA present study does not correspond with given study as in present study the ITA takes origin from thyrocervical trunk, SA, and VA in 201 (95.7%), 7 (3.3%) and 2 (1.0%) cases, respectively.…”

BACKGROUND The course and variations of thyroid arteries must be understood by surgeons to prevent bleeding during operative procedures of the thyroid gland. There is limited scientific literature regarding the radiological anatomy of thyroid arteries in this geographical area, the Garhwal region of Sub-Himalayan belt, which is considered to be the endemic belt of goiter. Computed tomography angiography provides a three-dimensional orientation of the vascular and surgical anatomy of the entire cervical region. AIM To estimate the proportion of variation in origin of thyroid arteries using Computed Tomography Angiography. METHODS Using Computed Tomography Angiography, the presence and origin of the superior thyroid artery, inferior thyroid artery, and thyroid ima artery were observed and assessed. RESULTS Out of total 210 subjects, superior thyroid artery was seen to be emerging from external carotid artery in 77.1% cases. The artery was found to be originating at the level of bifurcation of common carotid artery in 14.3% cases, whereas in 8.6% cases, it emerged as a direct branch of the common carotid artery. Similarly, the inferior thyroid artery was observed to be emerging from thyrocervical trunk, subclavian artery and vertebral artery in 95.7% cases, 3.3% and 1% cases, respectively. Thyroid ima artery was also reported in a subject, arising from the brachiocephalic trunk. CONCLUSION To avoid vascular injuries, excessive and uncontrollable bleeding, intra-operative difficulties, and post-operative issues, it is imperative for surgeons to be aware of the course and variations of thyroid arteries

Purpose and backgroundThe specialized literature has a low degree of information regarding the origin of the inferior thyroid artery (ITA). Our study was performed on computed tomography angiographies (CTAs), and the following aspects were observed: the origin of the ITA from the subclavian artery (SCA) or thyrocervical trunk (TCT), taking note of the distance of the origin of the ITA in relation to the origin of the SCA or the corresponding TCT, as well as the origin of the ITA, comparing right to left and according to gender. MethodsOur study was realized on a total of 108 ITA (64 on the right side and 44 on the left, with 48 in male subjects and 60 in females), analyzed on CTA. ResultsFrom the 108 arteries, we found the origin of ITA directly from the SCA in 31.48% of cases, and in 68.52% from the TCT. The distance between the origin of the right SCA and the origin of the corresponding ITA, was between 29.1-53.1 mm, while on the left side, the same distance was between 43.7-68.1 mm. The distance between the right TCT and the origin of the right SCA, was between 22.5-75.0 mm, and for the left side, it's between 48.7-56.8 mm. ConclusionsThe 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.
