BACKGROUND
Bow Hunter's syndrome (BHS) is a rare condition in which head rotation or extension temporarily compresses the vertebral artery (VA), reducing blood flow to the posterior circulation. Here, a 66-year-old male developed BHS when left neck rotation caused VA compression due to a congenital os odontoideum.
CASE DESCRIPTION
A 66-year-old male presented with loss of consciousness following hyperextension/left neck rotation. Imaging revealed a chronic odontoid fracture (Anderson Type II or here likely congenital os odontoideum) with tortuosity of the right VA in the V3 segment. Notably, a posteriorly dislocated odontoid fragment caused occlusion of the dominant right VA at the ponticulus posticus, thus causing BHS. Following C1-C2 fusion, the patient's symptoms resolved.
AN
A66-year-old male who sustained cervical hyperextension/left rotation at the C1-C2 level developed occlusion of the right VA and BHS due to an os odontoideum.
背景
弓猎综合征（BHS）是一种罕见病症，头部旋转或伸展时会暂时压迫椎动脉（VA），减少后循环的血流量。在此，一名66岁男性因先天性齿突骨，在左颈部旋转导致VA受压时患上了BHS。
病例描述
一名66岁男性在颈部过伸/左颈部旋转后出现意识丧失。影像学检查显示慢性齿突骨折（安德森II型，此处可能为先天性齿突骨），右侧VA在V3段迂曲。值得注意的是，一个向后脱位的齿突碎片在小脑后下动脉起始部导致优势侧右侧VA闭塞，从而引发BHS。C1-C2融合术后，患者症状缓解。
分析
一名66岁男性在C1-C2水平发生颈部过伸/左旋转，因齿突骨导致右侧VA闭塞和BHS。
