A 69-year-old man with impaired consciousness, right hemiplegia, and aphasia was admitted to our emergency room for thorough examination. Magnetic resonance imaging (MRI) and 3-dimensional computed tomography (3D CT) scan of the head revealed a cerebral infarction due to dissection of the left internal carotid artery. Contrast-enhanced CT prior to internal carotid artery stenting showed that the left elongated styloid process ran in close proximity to the left internal carotid artery, with a minimum distance of 2 mm. The patient underwent stenting at the internal carotid artery 16 days after disease onset. The patient was referred to our department for left elongated styloid process resection to reduce the risk of further internal carotid artery injury. Resection of the left styloid process through a cervical incision was performed. Six months after surgery, there was no recurrence of the internal carotid artery dissection.
一位 69 岁男性，因意识障碍、右侧偏瘫和失语症被收入我院急诊进行全面检查。头部磁共振成像（MRI）和三维计算机断层扫描（3D CT）显示由于左侧颈内动脉夹层导致脑梗死。颈内动脉支架置入术前行增强 CT 显示，左侧细长茎突与左侧颈内动脉非常接近，最短距离为 2 毫米。患者在发病后 16 天进行了颈内动脉支架置入术。患者因左侧细长茎突被转诊至我科，以降低进一步损伤颈内动脉的风险。通过颈部切口进行了左侧茎突切除术。术后 6 个月，颈内动脉夹层无复发。
