AIMS This study aimed to identify the clinical profiles of cervical spondylosis-related internal jugular vein stenosis (IJVS) comprehensively. METHODS A total of 46 patients, who were diagnosed as IJVS induced by cervical spondylotic compression were recruited. The clinical manifestations and imaging features of IJVS were presented particularly in this study. RESULTS Vascular stenosis was present in 69 out of the 92 internal jugular veins, in which, 50.7% (35/69) of the stenotic vessels were compressed by the transverse process of C1, and 44.9% (31/69) by the transverse process of C1 combined with the styloid process. The transverse process of C1 compression was more common in unilateral IJVS (69.6% vs 41.3%, P = 0.027) while the transverse process of C1 combined with the styloid process compression had a higher propensity to occur in bilateral IJVS (52.2% vs 30.4%, P = 0.087). A representative case underwent the resection of the elongated left lateral mass of C1 and styloid process. His symptoms were ameliorated obviously at 6-month follow-up. CONCLUSIONS This study proposes cervical spondylotic internal jugular venous compression syndrome as a brand-new cervical spondylotic subtype. A better understanding of this disease entity can be of great relevance to clinicians in making a proper diagnosis.

颈椎病颈内静脉压缩综合征。

目的本研究旨在全面鉴定与颈椎病相关的颈内静脉狭窄（IJVS）的临床特征。方法招募46例经颈椎压迫病诊断为IJVS的患者。IJVS的临床表现和影像学特征在本研究中尤为突出。结果92条颈内静脉中有69条存在血管狭窄，其中C1的横突压迫了50.7％（35/69）的狭窄血管，横突的压迫狭窄了44.9％（31/69）的血管C1与茎突结合。C1压缩的横向过程在单侧IJVS中更为常见（69.6％vs 41.3％，P = 0。027）而C1的横向过程与茎突压缩结合在双侧IJVS中发生的可能性更高（52.2％vs 30.4％，P = 0.087）。一个典型的案例是切除了C1和茎突的细长左外侧肿块。在六个月的随访中，他的症状明显改善。结论本研究提出颈椎病颈内静脉压迫综合征为一种新型的颈椎病亚型。对该疾病实体的更好理解与临床医生做出正确诊断具有极大的关系。结论本研究提出颈椎病颈内静脉压迫综合征为一种新型的颈椎病亚型。对该疾病实体的更好理解与临床医生做出正确诊断具有极大的关系。结论本研究提出颈椎病颈内静脉压迫综合征为一种新型的颈椎病亚型。对该疾病实体的更好理解与临床医生做出正确诊断具有极大的关系。
