摘　　要：目的:为右叶部分活体肝移植(LDLT)提供有关副肝右静脉(aRHV)的活体形态学资料,探讨64排螺旋CT(64-MSCT)显示副肝静脉的价值。方法:无肝病成人病例100例行64-MSCT增强扫描,对肝静脉期数据进行三维重建,观测统计aRHV的开口部位、出现率、数量、管径及引流范围。结果:aRHV开口部位位于下腔静脉(IVC)肝后段下份7∶00～8∶00间占78.4%(40/51),直径≥5.00 mmaRHV的出现率为28.0%;汇入IVC肝后段上、中、下份的aRHV分别占8.0%、24.0%和68.0%,管径分别为(5.98±1.86)、(4.38±1.11)mm和(5.81±1.93)mm。结论:aRHV出现率较高,以开口于IVC肝后段下份右后壁者居多,64-MSCT能较好地显示具临床意义的副肝静脉。Objective:To provide morphological data concerned with the accessory right hepatic vein(aRHV) in vivo for living donor liver transplantation(LDLT), and approach the value of 64-slice spiral CT(64-MSCT) on displaying accessory hepatic vein. Methods:100 non-illness adult livers were scanned by 64-MSCT, the hepatic vein stage data were used for three-dimensional reconstruction. The opening position, frequency, number, diameter and the draining scope of aRHV were observed.Results:The opening position of aRHV was 78.4%(40/51) between seven o’clock and eight o’clock in the lower part of inferior vena cana(IVC) behind liver. The frequency of aRHV with diameter more than 5.00mm was 28.0%. The percentage of aRHV inflowing to the upper, middle and lower part of IVC behind liver were 7.8%, 25.5% and 66.7%,respectively. The diameter of aRHV in each part of IVC were (5.98±1.86)mm, (4.38±1.11)mm and (5.81±1.93)mm, respectively. Conclusion:aRHV is very common. The opening position of aRHV is mostly at the right lower part of IVC behind liver. 64-MSCT can well display the accessory hepatic vein, which is clinically significant.
