摘要
摘要目的探讨颈性眩晕发病与椎动脉供血区脑血流量的变化及其发病机制.方法颈性眩晕患者９３例,年龄２６~８０岁,平均５４．５岁.病程１周~３０年,平均４６．２个月.由颈椎运动负荷试验诱使颈性眩晕患者其发病,同时使用近红外光谱仪动态观察患者左右两侧椎动脉供血区脑血流量的变化及其诱发症状情况.结果９３例患者中,被颈椎运动负荷试验诱发颈性眩晕发病者８５例,阳性率为９１％;近红外光谱仪检测椎动脉供血区脑血流量异常改变者８２例,阳性率为８８．２％.左右两侧椎动脉供血区脑血流变化的阳性率分别为６９．９％和７６．３％,两者间无统计学差异.结论颈性眩晕发病与椎动脉供血区脑血流量变化有关,左、右两侧椎动脉在颈性眩晕发病上权重相当.颈椎运动负荷试验和近红外光谱仪检查有助于颈性眩晕的诊断及鉴别诊断.关键词颈性眩晕,发病机制,近红外光谱仪,交感神经,椎动脉AbstractobjectiveTostudytherelationbetweenthechangesofcerebralbloodflowandcervicalvertigo,andresearchthepathogenesisofcervicalvertigo．Methods９３patientswithaverageageof５４．５year－oldwererandomlyselectedfromthepatientsofvertigo,whowerediagnosedofcervicalvertigobyanalysisoftheirmedicalrecord,examinationandtheeliminationoftheothertypesofvertigo．Thenthepatientisaskedtotakethecervicalmotionloadtest．Atthesametime,thepatient??sinducedsymptoms,theNIRScurveanditsdatachangesaredynamicallyobserved．Results８５patientsareinducedtosymptomswithincidenceof９１％．NIRSchangesarefoundin８２patientsof９３withadiseaseincidenceof８８．２％．Among８２cervicalvertigopatientswhohavetheNIRSchanges,６５arefoundwithchangesinthebloodsupplyingareaofleftvertebralartery(６９．９％),and７１arefoundwithchangesinthebloodsupplyingareaofrightvertebralartery(７６．３％)．Thereisnoobviousdifference(p＞０．０５)betweentheleftandtherightside．ConclusionCervicalvertigoisrelatedtothedysfunctionofvertebralartery,．Thereisnoobviousdifferencebetweentheleftandtherightareassuppliedbyvertebralarteryinpathogenesisofcervicalvertigo．ThecervicalmotionloadtestcombinKeedywwiotrhdsNIRSisvaluableforthediagnosisofcervicalvertigo．CervicalVertigo;Pathogenesis;Nearinfraredspectroscopy;Nervussympatheticus;Vertebralartery中图分类号R６８１．５文献标识码B文章编号１００８－６３１５(２０１５)１２－１０８８－０２
