This study reports important variations in branches of the subclavian artery in a singular cadaver. The origin of the left vertebral artery was from the aortic arch. On the right side, no thyrocervical trunk was found. The two branches which normally originate from the thyrocervical trunk had a different origin. The transverse cervical artery arose directly from the subclavian artery and suprascapular artery originated from the internal thoracic artery. This variation provides a short route for posterior scapular anastomoses. An awareness of this rare variation is important because this area is used for diagnostic and surgical procedures.
本研究报告了一具特殊尸体中锁骨下动脉分支的重要变异情况。左椎动脉起源于主动脉弓。右侧未发现甲状腺颈干。通常起源于甲状腺颈干的两个分支有不同的起源。颈横动脉直接起源于锁骨下动脉，肩胛上动脉起源于胸廓内动脉。这种变异为肩胛后吻合提供了一条捷径。认识到这种罕见变异很重要，因为该区域用于诊断和外科手术。
