摘要
目的:探讨多层面CT在肝移植受体术前评估中的应用价值。材料和方法:我们总结分析了自2003年11月至2004年8月52例接受多层面CT检查的晚期肝病患者。采用薄层动态增强扫描,横断面图像+CT血管造影技术,评估肝脏实质病变及血管变异情况。结果:其中接受肝移植手术26例,其中有6例肝动脉变异,与术前判断完全吻合。5例门脉癌栓形成及5例血栓形成中各有1例误诊。结论:多层面CT是一种快捷、无创、价廉的检查手段,可为肝移植受体术前评估提供详尽且准确的解剖及病变信息。
This article summarizes our experience and CT technique for the preoperative imaging of pa-tients being evaluated for liver transplantation.Materials and Methods:There were52cases(38males,14females)of patients with terminal stage hepatic diseases who anticipated undergoing liver transplantation hospitalized from Nov2003to Aug2004.We use a multidetector CT scanner(Lightspeed QX/i,GE Medical Systems,Milwaukee,Wis.)to image the hepatic arterial,hepatic venous,and portal vein anatomy.All data are transferred to commercially available workstations(AW3.1,GE Medical Sys-tems,Milwaukee,Wis.),where all post-processing of acquired data is performed.Results:26patients underwent liver transplantation,6patients have hepatic arterial aberrant which are consistent with the finding of the surgery.Each of1case among the5cases of cancerous embolism and5cases of thrombosis was misdiagnosed.Conclusion:The preoperative CT images can document important vascular and parenchymal variants that may alter the anticipated surgical procedure,or even preclude the recipient from undergoing surgery.MDCT and CTA imaging has the advantages of being quick to set up,safety,economy and is a perfect imaging modality.
