摘要
目的 分析神经科门诊头晕或眩晕患者颅内外血管狭窄发生频率，以及狭窄血管的分布情况，探讨导致头晕或眩晕的动脉狭窄原因。方法 对2001年1月～2001年12月神经科门诊筛选主诉为头晕或眩晕，且无其他神经系统局灶体征者1676例。应用经颅多普勒超声（TCD）检测颅内Willis环及颅外颈部血管。结果 （1）202例有脑血管的狭窄，血管狭窄的发生率为202／1676（12．10％）。其中，单纯颈动脉系统血管病变的发生率45．05％，高于单纯椎基底动脉系统32．18％（P〈0．01）；（2）椎动脉狭窄者占11．88％，其中，单侧椎动脉病变占79．167％，左右无明显差别；3.锁骨下动脉狭窄者占32．673％，其中伴盗血综合征者为28．79％。结论 临床上不能仅仅简单的把单纯头晕或眩晕患者诊断为功能性疾病或椎基底动脉供血不足。
Objective To discuss the common causes of dizziness and vertigo by detecting the stenosis incidence of the cerebral arteries in 1676 dizziness and vertigo patients with TCD. Methods Willis circle and some extracranial arteries were detected using TC-4040 or 8080 with 2 MHz and 4 MHz probes. The velocity,spectrum, acoustic frequency and PI were analysed. Results 1. Totally 202 patients suffered from the cerebral vascular disease without serious neurological symptoms. Vassular stenosis incidence was 12. 10% in paitents with dizziness and vertigo. The incidences of simple anterior circulation and simple posterior circulation stenosis were 45. 050% and 32. 178% respectively; 2. The incidence of VA stenosis was 11. 881% with single VA stenosis 79. 167%. No obvious difference was in the left and right side. 3. Incidence of subclavicular artery stenosis was 32. 673% with subclavicular steal syndrome 28. 788%. Conclusions We should not simply diasgnose the dizziness and vertigo as functional disease or vertebrobasilar ischemia.
