超声评估活体肝移植供体肝静脉临床价值的研究

Significance of Ultrasound in Displaying Hepatic Veins System of Donor before Living Donor Liver Transplantation

目的探讨超声在活体肝移植供肝肝静脉评估中的临床价值。方法回顾性分析17例活体肝移植供体,术前均行超声及CT检查,观测管径大于5mm中肝静脉(MHV)属支及右后下静脉(IRHV)情况。结果超声发现管径大于5mm MHV属支及IRHV的数目分别为8(S4)、7(S5)、5(S8)、8(IRHV),CT为8(S4)、7(S5)、9(S8)、14(IRHV),两者的一致率为73.7%(28/38),将MHVS8属支和IRHV的超声管径标准缩小至4mm再次统计,数目为8(S8)、14(IRHV),与CT的一致率为97.4%(37/38)。结论超声可用于评价活体肝移植供肝肝静脉情况。

Objective To evaluate the significance of ultrasound in displaying hepatic vein system of donor before living donor liver transplantion （LDLT）. Methods Seventeen cases of LDLT donors undergoing both ultrasound and CT examinations before operation were etrospectively analysed. Both examinations were supposed to display inferior right hepatic vein （IRHV） and branchs of middle hepatic vein （MHV） thicker than 5 mm. Results The number of MHV branchs and IRHVs thicker than 5 mm found out by ultrasound were 8 （$4）, 7 （S5）, 5 （S8）, 8 （IRHV） separately, and 8 （S4）, 7 （$5）, 9 （S8）, 14 （IRHV） by CT separately. The concordance rate was 73.7% （28/38）. Using 4 mm as ultrasound criterion for IRHV and MHV S8 branchs, it turned out to be 8 （S8）, 14 （IRHV）. The concordance rate reached to 97.4% （37/38）. Conclusion Ultrasound can be used to display the hepatic vein system of LDLT donor.
