“…No less important are the diagnostic or interventional (or both) procedures (for example a tracheostomy) that can lead to significant bleeding if the presence of a TIMA is not known [46,49].…”

The Thyroid Gland: A Revision Study on Its Vascularization and Surgical Implications

Background: The “classic” thyroid gland arterial vascularization takes into account two superior thyroid arteries (STA), two inferior thyroid arteries (ITA) and, occasionally, a thyroid ima artery (TIMA). The present review focuses on exploring the available data concerning thyroid gland arterial vascularization and its variations. Methods: Here, we analysed 49 articles from the last century, ranging from case reports to reviews concerning cadaver dissection classes, surgical intervention, and non-invasive techniques as well. Results: The harvested data clearly highlighted that: (i) the STA originates predominantly from the external carotid artery; (ii) the ITA is a branch of the thyrocervical trunk; and (iii) the TIMA is a very uncommon variant predominantly occurring to compensate for ITA absence. Conclusion: A systematic review of a highly vascularized organ is of great relevance during surgical intervention and, thus, the knowledge of normal anatomy and its modification is essential both for fact-finding and in surgery.

“…Finally, in 2018 Yohannan and colleagues described the TIMA's origin from the SA close to the VA's origin, stressing that the TIMA definition was completely arbitrary, in particular when defining its origin [49].…”

“…With hypoplastic or absent inferior thyroid arteries, the TIA has also been shown to have a compensatory function in blood supply. 17,18 Reports have also identified a relation between the presence of the TIA in parathyroid adenomas and goiter. 19,20 Depending on arterial course and length, the TIA can also supply the trachea, parathyroid glands, and thymus as a single branch or as multiple branched anastomoses.…”

Background: The thyroid ima artery (TIA) is an anatomical anomaly that commonly functions as an accessory blood supply for the isthmus and inferior aspect of the thyroid. Limited research has been performed to investigate the relative prevalence and clinical implications of the TIA in present literature.Methods: Dissections were conducted on cadavers in the anatomy laboratory at Touro College of Osteopathic Medicine, New York (Harlem Campus), with 94 subjects examined using standard methods to identify thyroid vasculature and to determine the presence of a thyroid ima artery. Known origins of the thyroid ima artery were also examined for possible branching. Results: Of the 94 cadavers, only one was found to have a thyroid ima artery present, suggesting a prevalence of 1.06 percent.Conclusions: The thyroid ima artery is significant in its influence in head and neck procedures as well as emergent airway creation. With its relative rarity, its presence is worthy of consideration as a possible hematological source for hemorrhage.

“…The TG isthmus is usually supplied by the ITA or less commonly by the BCA or the aortic arch [4]. Yohannan et al [14] reported an atypical anterior course of the TIA (between CCA medially and internal jugular vein laterally). The TIA coursed until to reach the TG inferior pole of the right lobe and branched to supply the anteroinferior and posteroinferior aspects of both lobes and isthmus.…”

“…TIA may have a variable course and supply to the TG inferior poles and the isthmus. TIA may also coexist with a brachiocephalico-carotid trunk (BCT) (fusion of the BCA with the LCCA), an aberrant right SCA of retroesophageal course, a variable course of the inferior laryngeal nerve (non-recurrent and recurrent) [8] and the ITA bilateral absence [14]. Knowledge of the existence of TIA variants is vital to avoid intraoperative hemorrhage during tracheotomy or cricothyroidotomy [6].…”

Purpose The current cadaveric report describes a rare case of a thyroidea ima artery (TIA) with multiple branching pattern over the trachea. Methods A cadaver dissection of the neck and thorax region of a formalin-embalmed 90-year-old male cadaver of a body donor took place. The body donation was made after a signed informed consent. Results The TIA variant originated from the brachiocephalic artery before its bifurcation into the right common carotid artery (CCA) and right subclavian artery (SCA). TIA further divided into three anterior and two posterior branches, with subsequent multiple division into smaller branches. All branches were located anterior and right side to the trachea. The anterior branches supplied the infrahyoid muscles and the posterior ones supplied the thyroid gland inferior lobes and the inferior parathyroid glands. The TIA coexisted with a brachiocephalico-carotid trunk, derived after the left CCA and left SCA fusion. Conclusion The presence of multiple arterial branches over the trachea creates a high risk for excessive bleeding during tracheotomy or cricothyroidotomy.
