椎动脉型颈椎病颈椎曲度与椎动脉CTA相关性的初步研究

The Preliminary Study about the Relevance between Cervical Curvature and Vertebral Artery CTA of Cervical Spondylosis of Vertebral Artery Type

目的：初步探求椎动脉型颈椎病颈椎曲度与椎动脉CTA的相关性。方法：选用2012年1月到6月我院13例椎动脉型颈椎病患者，其中男性3例，女性10例，年龄27～36岁，平均年龄为32．08岁，分别进行颈椎X线和椎动脉CTA检查。结果：颈椎曲度变直左侧CTA为2．04±0．41，右侧为2．01±0．33，颈椎曲度反弓左侧CTA为1．01±0．14，右侧为1．08±0．13，颈椎曲度正常左侧CTA为4．24±0．11，右侧为3．56±0．28；颈椎曲度异常，双侧椎动脉CTA与正常组存在显著的统计学差异，明显比正常椎动脉狭窄；7例颈椎曲度变直患者CTA进行相关性分析发现，曲度与左侧CTA的Pearson值为0．895，P〈0．05，与右侧CTA的Pearson值为0．782，P〈0．05，说明，当颈椎曲度变直后，曲度与椎动脉直径存在正相关性，曲度越小，椎动脉直径越小。结论：椎动脉型颈椎病颈椎曲度与椎动脉CTA存在相关性。

Objective： To preliminary study the relevance between cervical curvature and verte- bral artery CTA of cervical spondylosis of vertebral artery type. Methods： 12 patients with cervical spondylosis Of vertebral artery type were selected in hospital from January to lune 2012. 3 cases were male, and 10 cases were female. They were 27 to 36 years old, and the average age was 32.08. They all were checked up by the cervical X-ray and vertebral artery CTA. Results： Cervical curvature straightening at the left was 2.04±0.41, the right was 2.01 ±0.33; cervical curvature inverse arch-shaped at the left was 1.01±0.14, the right was 1.08±0.13; cervical curvature normal at the left was 4.24±0.11, the right was 3.56±0.28. It was significant statistical difference between abnormal and normal group about cervical curvature abnormal and bilateral vertebral artery CTA. k was obvi- ously narrower than the normal vertebral artery. 7 patients with cervical curvature straightening were conducted correlative Analysis, found that the Pearson of curvature and the left CTA was 0.895, P〈0.05, the Pearson of curvature and the right CTA was 0.782, P〈0.05, it could explain that after cervical curvature straighten, curvature and Vertebral artery diameter exist positive correla- tion, the more curvature small, the more vertebral artery diameter small. Conclusion： Cervical cur- vature and vertebral artery CTA of cervical spondylosis of vertebral artery type exist relevance.
