摘要
目的:通过比较影像的研究方式,探讨MSCTA与3D-DCE-MRA在活体供肝移植术前评估供体血管中的临床应用价值。材料与方法:30例拟行活体供肝移植术的供体,术前分别行MSCTA和3D-DCE-MRA检查,4名医师评价图像满意度及观察变异血管例数,图像满意度分为4级,变异血管主要观察非MichelsⅠ型肝动脉、肝Ⅳ段(肝左内叶)肝右动脉供血、门静脉三分支、肝右后下静脉、肝Ⅷ段静脉汇入肝中静脉,其中6例进行了供肝移植术并作术中比照,所有数据进行统计学分析。结果:二者显示肝动脉及门静脉的平均图像满意度无显著差异(P>0.05),显示肝静脉情况有显著差异(P<0.05)。二者显示肝右后下静脉及肝Ⅷ段静脉汇入肝中静脉情况有显著差异(P<0.05),余未见显著差异(P>0.05)。6例供体术中记录与3D-DCE-MRA结果完全吻合,MSCTA结果仅肝右后下静脉与肝Ⅷ段静脉汇入肝中静脉与术中记录不吻合,其它均吻合。结论:MSCTA与3D-DCE-MRA在评估肝动脉及门静脉方面无显著差异。在评估肝静脉方面,3D-DCE-MRA优于MSCTA。3D-DCE-MRA可作为活体供肝移植术前评估供体血管情况的首选检查方法。
To determine whether MSCTA and 3D-DCE-MRA will be able to periorm a complete and accurate role in preoperative evaluation of the hepatic vascular anatomy for living liver donors. Methods： Thirty living donor candidates underwent preoperative MSCTA and 3D-DCE-MRA. Data analysis was performed by 4 reviewers（2 radiologists and 2 surgeons）, based on source images and 3 dimensional postprocessing. Detelinination of image satisfaction degree was based on 4 grades（l： nondiagonostic; 2： fair; 3： good; 4： excellent）. They should also count the numbers of aberrant vessels, including non Michels I type, segment IV branch from right hepatic artery, trifurcation of portal vein branches, right posterior inferior hepatic vein and segment Ⅷ branch of hepatic vein draining to middle hepatic vein. Six donors were living donor in liver transplantation. Surgical findings were used as a standard of reference and then statistical analysis was performed. Results： Both techniques were proved to be efficient to evaluate hepatic artery and portal vein for potential living donors. There was no significant dif ference between the two. The main advantage of 3D-DCE-MRA lies in the ability to assess the hepatic vein systems more accurately. There was a significant difference between the two. Conclusion： 3D-DCE-MRA could be the first choice to assess potential living donor＇s vessels.
