摘　　要：目的探讨64层螺旋CT对肝静脉显像的价值,为临床活体肝移植(LDLT)提供有关肝中静脉(MHV)的形态学资料。资料与方法对50例无肝病成人行肝静脉64层螺旋CT增强扫描及三维重组,测量MHV相关数据并进行统计分析。结果 64层螺旋CT增强扫描能够清晰显示肝静脉主干及其4级以上分支;MHV与肝左静脉(LHV)共干者占56.0%(28/50);MHV与LHV、肝右静脉(RHV)在下腔静脉(IVC)开口处间的距离分别为(2.20±1.55)mm、(11.86±6.48)mm;MHV主干和外科干长分别为(62.86±12.46)mm、(16.14±12.12)mm;MHV主干上壁距IVC汇入口1～4cm处及起始处至肝膈面的深度分别为(13.41±4.60)mm、(24.16±4.36)mm、(32.64±4.30)mm、(38.10±4.56)mm、(34.82±7.76)mm;MHV与IVC的夹角为(52.21±12.41)°。结论 64层螺旋CT是一种可靠的临床检测方法,可作为LDLT较为可靠的肝静脉临床检测手段;MHV汇入IVC的部位、与LHV的关系及在肝内的定位等均有助于指导手术方案的制定及实施。Objective To evaluate the value of 64 slice spiral CT（64 MSCT） in displaying hepatic vein,and to provide morphology data of middle hepatic vein （MHV） for living donor liver transplantation（LDLT）.Materials and Meth-ods Fifty livers of healthy adult were scanned by 64 MSCT.The data of hepatic vein was three-dimensional reconstructed and the MHV were analyzed retrospectively.Results The trunk and the 4th level tributaries of MHV were displayed clearly on 64 MSCT.56.0%（28/50） of the MHV were displayed had common trunk with LHV.The distance between MHV and LHV opening to the IVC was（2.20±1.55）mm,and the distance between MHV and RHV opening to the IVC was（11.86±6.48）mm .The length of main trunk and the surgical trunk was（62.86±12.46） mm and（16.14±12.12） mm.The angle between MHV and IVC was（52.21±12.41）°.Conclusion 64 MSCT can display the position of MHV opening to the IVC,and the relationship of MHV and LHV,which conduce to liver transplantation.
