摘　　要：目的应用彩色多普勒超声评价健康成人Willis环侧支循环的功能及分析男、女之间的差异。方法选择286例健康成人,采用经颅多普勒血流成像(TCCDFI)及超声造影成像技术(CEUS),观察颅内动脉走行及血流方向。并通过压迫颈总动脉(CCA),观察大脑前动脉(ACA)的血流方向变化及大脑后动脉(PCA)的血流速度变化,分别评价Willis环前、后交通动脉侧支循环功能。结果 286例健康成人中,TCCDFI颅内动脉清晰显示的213例,其中,男性118例,女性95例,另73例颅内动脉未成功显示的成人中,男、女各选10例行CEUS后能清晰显示。男、女性经TCCDFI及CEUS清晰显示颅内动脉的128、105例中,前交通动脉功能开放男111例(86.7%)、女88例(83.8%),后交通动脉左侧男40例(31.2%)、女35例(33.3%),右侧男43例(33.6%)、女36例(34.3%),男、女性之间交通动脉开放率差异无统计学意义(P>0.05)。结论 TCCDFI及CEUS能实时观察颅内动脉走行及血流方向,评价前、后交通动脉侧支循环功能,男、女性前、后交通动脉存在的侧支循环比率无显著差异。Objective To evaluate the function of color Doppler on the collateral circulation Willis of circle in healthy adults and analyze the difference between man and woman.Methods 286 healthy adults were enrolled in this study.The course and blood flow direction of their cerebral arteries were observed by transcranial color Doppler flow imaging （TC- CDFI） and contrast-enhanced ultrasound （CEUS）.The function of anterior and posterior communicating arteries （ACoA and PCoA respectively） of Willis circle were respectively assessed by the changes of direction of anterior cerebral artery （ACA） and blood flow velocity of posterior cerebral artery （PCA） during common carotid artery （CCA） compression. Results Among 286 healthy adults,213 cerebral arteries could be clearly visualized by TCCDFI,ineluding 118 men and 95 womcn.lO men and women each selected of remaining 73 cases could be seen only after CEUS.The rate of the func- tional pateney rate of ACoA for men and women was 86.7% （111 cases） and 83.8% （88 eases）,left PCoA was 31.2% （40 cases） and 33.3% （35 eases）,right PCoA was 33.6% （43 cases） and 34.3% （36 cases）,respectively.There was no sig- nificant difference between man and woman （P〉0.05）.Conclasion The course and blood flow direction of their cerebral arteries can be observed real-timely.The functional pateney of ACoA and PCoA can be evaluated by TCCDFI and CEUS.The functional patency rate of communicating artery for man and woman exists no significant difference.
