TCD、CDFI对头晕、眩晕患者检测的临床意义

目的分析头晕、眩晕患者的TCD、CDFI检测资料,探讨引起头晕、眩晕症状的血管性病因。方法采用RIMED公司生产的Trans-Link9000型TCD检测仪,以2MHz、4MHz探头分别检测颅内外各血管;采用PHILIPS公司生产的IU22彩色多普勒超声,分别用线阵探头和凸阵探头观察椎动脉颅外段(VAE)的走行、内径、内膜、血流充盈、血流方向等情况。结果 320例头晕、眩晕患者中,46例存在血管狭窄,占14.5%;双侧椎动脉管径不对称112例,占35.0%;椎动脉走行扭曲12例,占3.75%。头晕患者血管狭窄的发生率为12.25%,眩晕患者为17.85%,两者比较差别显著(P<0.01)。头晕患者中椎-基底动脉狭窄发生率为3.85%,眩晕患者为14.28%,两者比较差别显著(P<0.01)。结论 TCD、CDFI可以为临床探求头晕、眩晕患者的血管性病因提供线索,并能为治疗及预后提出建议。

Clinical value of TCD and CDFI in dizziness or vertigo patients

Objective To approach vascular etiopathogenisis of dizzines or vertigo patients.Methods RIMED Trans-Link 9000 transcranial Doppler ultrosonography(TCD)with the probe frequency of 2Mhz and 4MHz was used to acquire the intra-and extra-cranial cerebral artery Doppler imaging.PHILIPS company IU22 color Doppler flow imaging(CDFI) was used to acquired the extra-cranial veterbral Doppler imaging,include course,inner diameter,inner membrane,blood flow direction and engorge.Resluts 46 patients with vascular stenosis in 320(occupy 14.5%).112 patients with dissymmetry in two vertebral arteries(occupy 35.0%),and 12 patients with twisted vertebral arteries(occupy 3.75%).Stenosis incidences of the vessels of the dizziness and vertigo patients were 12.25% and 17.85% respectively.There was significant difference in two groups(P<0.01).Stenosis incidences of vertebro-basilar stenosis of the dizziness and vertigo patients were 3.85% and 14.28% respectively.There was significant difference in two groups(P<0.01).Conclusion TCD and CDFI are accurate,no-injured,can be used to provide clue of vascular etiopathogenisis of dizzines or vertigo patients for clinical doctors,they can also be used to giving some advice on therapy and prognosis.
