摘要
目的:应用交感神经皮肤反应(SSR)检查了解椎基底动脉供血不足性眩晕(VBI)患者交感神经反射活动,并探讨SSR对VBI的诊断价值。方法:对56例VBI患者在急性发作期及恢复期行SSR检查,并与56例健康人作对照。结果:VBI组急性发作期SSR潜伏期(Lat)、波幅(Amp)上肢分别为(1.53±0.35)s,(2.34±1.00)mV;下肢分别为(2.07±0.38)s,(1.21±0.55)mV。恢复期Lat,Amp上肢分别为(1.40±0.20)s,(2.82±1.00)mV;下肢分别为(1.81±0.22)s,(1.74±0.77)mV。正常对照组Lat,Amp上肢分别为(1.35±0.14)s,(2.90±1.29)mV;下肢为(1.78±0.16)s,(1.78±0.80)mV。VBI组急性发作期SSRLat及Amp较正常对照组差异均有显著性意义(q=4.48～7.99,P<0.01),SSR总异常率为66%(37/56)。恢复期Lat和Amp较正常对照组差异无显著性意义(P>0.05),但SSR异常率为9%(5/56)。结论:VBI患者可出现交感神经功能暂时性损害,病情控制后交感神经功能可随之改善,SSR检查可作为VBI诊断的参考指标。
AIM:To examine sympathetic reflex activity in vertebrobasilar ishcemia(VBI) pa tients with sympathetic skin response(SSR) and to explore the diagnostic value o f SSR in VBI. METHODS:SSR examination was performed in 56 VBI patients in acute episode and compared with that of 56 healthy persons. RESULTS:In VBI group,the SSR latent period(Lat) and amplitude(Amp) of upper li mb in acute episode were (1.53±0.35)s and (2.34±1.00)mV while those of lower limb were (2.07±0.38)s,(1.21±0.55)mV.Lat and Amp of upper limb in recove ry stage were (1.40±0.20)s,(2.82±1.00)mV;while those of lower limb were (1.81±0.22) s and (1.74±0.77)mV.In control group,Lat and Amp of upper limb w ere (1.35±0.14)s, (2.90±1.29)mV,while those of lower limb were (1.78±0.1 6)s,(1.78±0.80)mV.The SSR Lat ad Amp in VBI group in acute episode were sig nificantly different from those of control group(q=4.48-7.99,P< 0.01),SSR tot al abnormality rate was 66%(37/56).

Transient functional lesion of sympathetic nerve may occur in VBI,w hich can be improved with control of disease condition.SSR examination may be us ed as a reference in diagnosis of VBI.
