中文摘要
舌骨或甲状腺软骨对颈总动脉（CCA）的机械性刺激可导致颈总动脉狭窄和脑梗死。一名71岁男性因症状性颈总动脉狭窄就诊。影像学显示在与甲状腺软骨接触部位存在颈总动脉斑块，超声显示吞咽时存在动态压迫。尽管颈动脉支架置入术在技术上成功，但梗死仍可复发，且无典型的支架相关并发症。斑块可能在持续的外部机械应力下被支架挤压，导致间歇性突出。追加支架置入防止了复发。本病例强调了在选择治疗策略时考虑外部机械因素的重要性。
英文摘要
Mechanical stimulation of the common carotid artery (CCA) by the hyoid bone or thyroid cartilage can cause common carotid artery (CCA) stenosis and cerebral infarction. A 71-year-old man presented with symptomatic CCA stenosis. Imaging revealed CCA plaque at the site of contact with the thyroid cartilage, and ultrasonography revealed dynamic compression during swallowing. Despite technically successful carotid artery stenting, infarctions can recur without typical stent-related complications. The plaque may be trapped by the stent under persistent external mechanical stress, resulting in intermittent protrusions. Additional stenting prevented the recurrence. This case highlights the importance of considering external mechanical factors when selecting a treatment strategy.
