摘　　要：目的探讨64层螺旋 CT 肝静脉成像技术显示正常人肝静脉变异的可行性。方法选取75例行腹部 CT 检查的无肝脏疾病患者,进行肝静脉成像扫描。观察肝静脉回流、肝静脉引流肝段的情况,并按3种解剖分型(Nakamura、Marcos 及 Kawasaki 分型)分别对肝静脉进行分型。结果肝右静脉单独汇入下腔静脉,肝左静脉和肝中静脉先汇合后再注入下腔静脉,占86.7%(65/75);肝右静脉、肝中静脉及肝左静脉分别单独汇入下腔静脉,占13.3%(10/75)。肝右静脉 Nakamura 分型:A 型占49.4%(37/75),B 型占37.3%(28/75),C 型占13.3%(10/75)。肝中静脉 Marcos分型:A 型占56.0%(42/75);B 型占24.0%(18/75);C 型20.0%(15/75)。肝左静脉 Kawasaki 分型:Ⅰ型占40.0%(30/75);Ⅱ型占60.0%(45/75)。结论正常人肝静脉变异率较高,多层螺旋 CT 静脉成像可提供细微的静脉系统分支图像。Objective To analyze variations of hepatic vein in healthy people with 64-slice spiral CT. Methods Seventy-five healthy subjects underwent multi-slice spiral computed （MSCT） hepatic venography. The anatomy of the junction of the hepatic veins with the inferior vena cava and the intrahepatic drainage territory of the hepatic veins and tributaries were evaluated. The hepatic veins were classified according to three anatomic classification （Nakamura＇s, Marcos＇s and Kawasaki＇s classification） methods respectively. Results There was a common trunk of the middle and left hepatic veins before joining the IVC in 86.7 % （65/75）of the cases. In 13.3% （10/75）of the cases, the three main hepatic veins joined the IVC separately. The ratios of Nakamura＇s classification type A, B, C of hepatic veins were 49.4 % （37/75）, 37.3 % （28/75）, and 13.3 % （10/75） respectively. The ratios of Marcos＇s classification type A, B, C of hepatic veins were 56.0 % （42/75）, 24.0 % （18/75）, and 20. 0 % （15/75） respectively. The ratios of Kawasaki＇ s classification type I , II of hepatic vein were 40.0 % （ 30/75 ） and 60.0 % （45/75）. Conclusion Multi-slice spiral CT hepatic venography can provide visualization of peripheral hepatic venous branches in details.
