摘　　要：目的评估MSCT肝动脉造影诊断肝动脉解剖和变异情况在肝移植受体术前血管评价中的应用价值。方法选取自2006年7月至2007年1月共75例预行肝移植的晚期肝病患者,均行肝脏动脉期扫描、肝动脉重建。由两位放射科医师对图像进行评估,包括肝动脉解剖和变异类型情况并与手术结果对照,统计分析诊断的灵敏度、特异度、阳性预测值及阴性预测值。结果75例中接受肝移植手术者共53例,MSCT检查发现肝动脉变异Ⅱ～Ⅹ型共15例,与手术结果对照,诊断的灵敏度：92.5%,特异度：100%,假阴性率：7.5%,假阳性率：0%。结论MSCT是一种快捷、简便、无创、价廉的检查手段,可有效评估肝移植受体术前的肝动脉解剖和变异情况。Objective To assess the value of computed-tomography angiography （CTA） in assessment of hepatic artery of peroperative liver transplantation recipient by multiple spiral CT （MSCT）. Methods Seventy-five patients with terminal stage hepatic diseases who anticipated undergoing liver transplantation hospitalized from July 2006 to January 2007 were performed by GE light-speed scanner underwent contrast-enhanced scans. With hepatic artery reconstructions, two radiologists experienced in abdominal radiology assessed the anatomy aberrant of hepatic artery. After the assessment results were compared with the results of surgery in each patient, the sensitivity, specificity, false negative rate and false positive rate of MSCT were analysed. Results Of the 53 patients who were in indication underwent liver transplantation, 15 had hepatic arterial aberrant. Being consistent with the finding of the surgery, the sensitivity, specificity, false negative rate, false positive rate of MSCT were 92.5 %, 100 %, 7.5% and 0 % respectively. Conclusions The preoperative CT images can document important hepatic artery variants that may alter the anticipated surgical produce. MSCT angiography has the advantages of being quick to set up, economy and is a perfect imaging modality.
