摘　　要：目的探讨正常人大脑外侧面浅表吻合静脉的CT血管成像表现。方法采用64层螺旋CT对90例受检者行头部CTV检查,应用CT三维重建技术重建大脑浅表吻合静脉的三维血管影像。结果①CTV图像中大脑浅表静脉吻合分为6型,Ⅰ～Ⅵ型分别占:34%(31例)、43%(39例)、9%(8例)、49%(44例)、33%(30例)及3%(3例);浅表静脉间的吻合个体差异较大,单侧大脑半球浅表静脉吻合显示类型以1～3种居多,3种以上较少见,8%(7例)双侧大脑半球未发现任何类型的浅表静脉吻合;②参与构成静脉吻合的浅静脉共349支,左侧182支,右侧167支,两侧比较差异无统计学意义(P>0.05);Trolard静脉、Labbe静脉及参与构成静脉吻合的Sylvian静脉的数量分别为97支、112支、140支。结论 64层螺旋CT血管成像是一种简便、快速、无创性显示大脑浅表吻合静脉的检查手段,可为临床相关手术入路的选择和脑血管疾病的诊断提供依据。Objective To explore the normal computed tomgraphic venography（CTV） features of the superficial anastomotic veins.Methods 90 patients underwent thin-section enhanced spiral CT scan of head.CT venography（CTV） of cerebral superficial anastomotic veins was reconstructed adopting different methods.Results ① The anastomosis of cerebral superficial veins could be classified into 6 types.Ⅰ～Ⅵ types accounted for about 34%（31 cases）,43%（39 cases）,9%（8 cases）,49%（44 cases）,33%（30 cases） and 3%（3 cases） respectively.The anastomosis of cerebral superficial veins was variable for the individuals,with the majority of 1 to 3 types of anastomosis in the unilateral cerebral hemisphere.However,no any kinds of anastomosis had ever been found on both sides of the brain hemispheres for seven cases（8%）.②A total of 349 superficial anastomotic veins constituted the venous anastomosis,with the left side of 182,and the right of 167.There was statistical difference between the bilateral superficial anastomotic veins（P0.05）.The number of Trolard vein,Labbe vein and Sylvian veins was respectively 97,112,and 140.Conclusions 64 detector row helical CT is a rapid and noninvasive method to depict the cerebral superficial anastomotic veins,thus it is helpful for the early diagnosis of venous disease and selection of related surgical approach.
