Pedicle screw insertion has been known to have several complications even in the most skilled surgical hands. However, injury to the thoracic aorta during pedicle screw insertion is rare, delayed presentation secondary to pseudoaneurysm is even rarer, the pseudoaneurysm formation caused by a series of malpositioned pedicle screws has perhaps not been reported so far.
In this paper, we report here a case in which inadvertent injury to the thoracic aorta resulted in pseudoaneurysm, its manifestation was initially vague, resulting in a delayed diagnosis. Delayed aortic pseudoaneurysm or injury can be asymptomatic for a long time. Patients with renewed or continued back pain should alert orthopaedic surgeons regarding the possibility of pseudoaneurysms, regardless of the period that has elapsed after pedicle screw implantation.
即使是在最熟练的外科医生手中，椎弓根螺钉插入也已知会有几种并发症。然而，在椎弓根螺钉插入过程中损伤胸主动脉是罕见的，假性动脉瘤引起的延迟表现更罕见，由一系列错位的椎弓根螺钉引起的假性动脉瘤形成迄今尚未报道。
本文报道了一例意外损伤胸主动脉导致假性动脉瘤的病例，其表现最初较为模糊，导致诊断延迟。延迟性主动脉假性动脉瘤或损伤可长期无症状。对于接受过椎弓根螺钉植入术的患者，无论在植入后经过多长时间，如果出现新的或持续的背痛，都应引起矫形外科医生对假性动脉瘤的可能性的警惕。
