Cervical rib is a congenital phenomenon that usually occurs in association with upper-limb neurovascular symptoms. The presence of a cervical rib displaces the great vessels that cross the thoracic outlet superiorly and proceed into the neck. We report an unusual case of iatrogenic hemorrhage during a tracheostomy in a patient whose right subclavian artery had been displaced by a cervical rib. Our aim is to alert surgeons to the hidden risks of this phenomenon.
颈肋是一种先天性现象，通常与上肢神经血管症状相关。颈肋的存在会使穿过胸廓出口的大血管向上移位并进入颈部。我们报告了一例气管切开术中发生医源性出血的罕见病例，该患者的右锁骨下动脉因颈肋而移位。我们的目的是提醒外科医生注意这种现象的潜在风险。
