Abstract:
During the routine dissection of an 86-year-old Caucasian male cadaver, an accessory inferior thyroid artery originating from the left suprascapular artery was detected. In addition to the existence of inferior and superior thyroid arteries, a third thyroid artery arising from the left suprascapular artery was present at the left of these arteries; this artery was determined as the accessory inferior thyroid artery. Again, the left internal thoracic artery arose from the thyrocervical trunk. The internal thoracic artery originated near the thyrocervical trunk's origin point and descended vertically. The thyrocervical trunk ended near the medial border of the anterior scalene muscle after giving rise to the inferior thyroid, transverse cervical and suprascapular arteries.
