(1) A common origin of the brachiocephalic trunk and left common carotid artery (the so-called bovine aortic arch). (2) A high pretracheal BCT course (calibre 1.29\u00a0cm, length 2.9\u00a0cm) with its upper margin 1.74\u00a0cm above the manubrial notch, crossing the anterior trachea from left to right. (3) A TIA arising from the BCT immediately proximal to its bifurcation and supplying both thyroid lobes. (4) An inferior mediastinal loop of the right subclavian artery (1.72\u00a0cm) with an intrathoracic origin of the right vertebral artery at 0.99\u00a0cm below the neck of the first rib. (5) A right SIA (calibre 1.1\u00a0mm) arising from the right vertebral artery at the level of the C7 transverse process in the TVA configuration, passing through the C7 transverse foramen and descending posterior to the necks of ribs 1\u20133. In addition, bilateral poor sternoclavicular joint articulation converted the suprasternal notch into an interclavicular space simultaneously containing the BCT, TIA, and thyroid isthmus.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This combination of variants places multiple vessels in a shared pretracheal\/interclavicular operative plane and appears to be undocumented as a combined pattern in the anatomical literature reviewed for this report.
