en Editorial Editorial <p dir="ltr" style="text-align: justify">The thyrocervical trunk most commonly arises from the upper portion of the first segment&nbsp;of the subclavian artery, close to the medial edge of the scalenus anterior muscle and after&nbsp;short distance is divided to the inferior thyroid, transverse cervical, and suprascapular&nbsp;artery. This study reports important variations in branches of the thyrocervical trunk in&nbsp;a singular female cadaver. On the right side, no thyrocervical trunk was found. The two&nbsp;branches which normally originate from the thyrocervical trunk had a different origin. The&nbsp;superficial cervical, suprascapular and internal thoracic arteries arose from the common&nbsp;trunk artery. An awareness of this rare variation is important because this area is used for&nbsp;diagnostic and surgical procedures.</p> Subclavian artery, Thyrocervical trunk, Variation complex, Neck posterior triangle 101 105 http://anatomyjournal.ir/browse.php?a_code=A-10-96-1&slc_lang=en&sid=1 Hassan Hassani Bafrani hhassanib@gmail.com 10031947532846001185 10031947532846001185 No Gametogenesis Research Center, Kashan University of Medical Sciences, Kashan, Iran.
