BACKGROUND
This retrospective case report describes a rare presentation of VBI in a young male patient.
AIMS
Share a rare cause of VBI in a young patient.
MATERIALS & METHODS: The patient presented with recurrent episodes of dizziness and a history of several cerebellar infarcts. Imaging revealed the right vertebral artery was being mechanically compressed by the right superior cornu of the thyroid cartilage during mouth opening. Surgical resection of the right superior cornu of the thyroid cartilage was performed.
RESULTS
Intraoperative angiography revealed a right vertebral artery without compression during mouth opening.
DISCUSSION
Clinicians should consider the thyroid cartilage as a potential source of recurrent VBI due to mechanical compression of the VA.
CONCLUSION
Resection of the causative portion of the thyroid cartilage resolved the compression in this case, and should be employed in similar cases. Laryngoscope, 133:1214-1217, 2023.
背景
本回顾性病例报告描述了一名年轻男性患者椎动脉缺血（VBI）的罕见表现。
目的
分享一名年轻患者VBI的罕见病因。
材料与方法
患者出现反复发作的头晕，并有多次小脑梗死病史。影像学检查显示，张口时右侧椎动脉受到甲状软骨右上角的机械性压迫。遂对甲状软骨右上角进行手术切除。
结果
术中血管造影显示，张口时右侧椎动脉无压迫。
讨论
由于椎动脉受到机械性压迫，临床医生应将甲状软骨视为复发性VBI的潜在病因。
结论
切除甲状软骨的致病部分可解决本例中的压迫问题，类似病例也应采用此方法。《喉镜》，2023年，第133卷，第1214 - 1217页
