摘要
应用经颅多普勒(TCD)检查对一些缺血性脑血管病所致眩晕进行鉴别诊断。方法:对椎基底动脉短暂缺血性眩晕(A组)、偏头痛(B组)、过度换气综合征(C组)和高血压病(D组)等病例,进行经颅多普勒常规检查(TCD-R)、过度换气1min(TCD-HV)和自主屏气 1min(TCD-B)检查,测定椎基基底动脉的收缩期峰流速(Vs)和舒张期末峰流速(Vd)。结果:A组、B组和D组的三项测试中Vs和Vd皆降低,以D组最为明显,A组、B组降低的程度相似,而C组则无明显降低。A组的Vs在TCD-B测试中异常发生率高于B组及C组,明显低于D组;在TCD-HV测试中低于D组和C组,高于B组,在TCD-R测试中明显低于D组而与B组和C组无差异。A组的Vd异常率,在TCD-R测试中低于D组而与B组、C组无明显差异。结论:TCD检查有助于对缺血性脑血管病所致眩晕的鉴别诊断。
Objective: To diagnose differentially the vetigo induced by some ischemic cerebrovascular disorder. Method:Patients with vertebrobasilar artery transient ischemic vertigo (group A),migraine (group B), hyperventilation syndrome (group C ), hypertension (group D ) are measured by using TCD functional examination which included blood peak velocity of systolic (Vs) and diastolic (Vd) end-period of vertibrobasilar artery of routine TCD (TCD-R),one minute hyperventilation TCD (TCD-HV) and one minute voluntary apnea TCD (TCD-B) respectively. Result:It showed that the Vs,Vd are decreased under the three conditions in A,B and D groups. The most apparent decrease are obversed in D group. The values of the decrease are similar between group A and B. No changes are found in C group. The abnormal Vs incidences of TCD-B measurement in group A are higher than those in group B and C,but significant lower than those in group D;and in TCD-HV test lower than group D and C,higher than group B;in TCD-R test,lower than group D,and no difference with group B and C. The abnormal incidences of Vd in group A are lower than group D and higher than group B in TCD-B test. In TCD-HV test,the group A abnormol incidences are lower than group D but higher than group B and C.In TCD-R test, the abnormal incidences are lower than group D and no difference between group B and C. Conclusion: The TCD measuremen is useful for differential diagnosis of vertigo induced by ischemic cerebrovascular disorders.
