摘要
目的探讨多层螺旋CT（MSCT）在评价椎基底动脉供血不足（VBI）与交感神经关系中的价值。方法2007年4月至2008年4月间就诊的56例行颈部血管CT检查患者，男30例，女26例，年龄34～76岁，平均50．6岁。经I晦床排除有VBI症状者32例纳入第一组；经临床和辅助检查诊断为VBI，排除椎动脉本身疾病且有交感神经症状者24例纳入第二组。所有患者均按预订扫描计划进行平扫、增强和后处理，观察并记录横突孔的径线、面积、相应层面椎动脉、横突孔的面积和比值，结果由两位放射科医师采取双盲法观察。结果①测量了所有患者横突孔的长径、短径、面积和椎动脉面积以及横突孔与椎动脉的面积比值。②用横突孔与椎动脉的面积比值衡量了第二组中有交感神经症状的24例共38个椎动脉狭窄水平的比值，显示均大于正常对照组比值的上限。结论@MSCT能准确的测量横突孔和椎动脉的径线、面积和横突孔与椎动脉的面积比值。②利用横突孔与椎动脉的面积比值能评价交感神经在VBI中的作用。
Objective To explore the value of multi slice spiral computed tomography in evalua- ting the relationship between vertebral -basilar insufficiency and sympathetic nerve. Methods Fifty - six patients who received CT angiography of neck vessels （30 men and 26 women; age range, 34 -76 years; mean age, 50.6 years） were divided into two groups： the first group included the patients who didn＇ t show any symptom of vertebral - basilar insufficiency ; the second group included the patients who were verified as vertebral - basilar insufficiency with symptom of sympathetic nerve and exclude vertebral artery disease by clinical doctors and radiologists. All patients underwent CT scan and post reconstruction according to standard examine program. Meanwhile, dimensions, area and ratio between transverse foramen area and vertebral artery area were measured. Results The diameter of transverse foramen, vertebral artery and the ratio between transverse foramen area and vertebral artery area was measured. The ratio between transverse foramen area and vertebral artery area of vertebral - basilar insufficiency patients with symptom of sympathetic nerve were larger than normal group. Conclusions Firstly, post reconstruction techniques of MSCT and original image are accurate and sensitive in studying the relationship between vertebral -basilar insufficiency and sympathetic nerve. Secondly, MSCT could ensure the relationship between vertebral- basilar insufficiency and sympathetic nerve.
