目的：评价右膈下动脉（RIPA） c臂计算机断层扫描（CT）在肝细胞癌（HCC）患者经导管动脉钙化治疗中的价值。材料与方法：2007年12月至2008年4月，对32例HCC患者进行了RIPA c臂CT前瞻性检查。两名进行c臂CT的介入放射科医生将c臂CT提供的额外信息评估为1级（没有额外信息）、2级（增加信息但对治疗计划没有影响）或3级（增加信息但对治疗计划有影响）。记录肿瘤喂食器和系统-肺分流器喂食器。结果：32例患者中，c臂CT提供的信息9例（28%）为1级，20例（63%）为2级，3例（9%）为3级。从RIPA的c臂CT扫描中最常见的附加信息是肿瘤和全身-肺分流的区分。22例（69%）患者观察到来自RIPA的系统-肺动脉分流，最常见的系统-肺动脉分流的馈线是奇型食管分支。结论：在怀疑有RIPA供血的HCC化疗栓塞期间，RIPA的c - art CT为肿瘤与非肿瘤状态的区分提供了额外的成像信息。
PURPOSE: To assess the usefulness of C-arm computed tomography (CT) of the right inferior phrenic artery (RIPA) in transcatheter arterial chernoembolization of patients with hepatocellular carcinoma (HCC).MATERIALS AND METHODS: From December 2007 to April 2008, C-arm CT of the RIPA was prospectively performed in 32 patients with HCC. Two interventional radiologists who performed C-arm CT assessed the additional information provided with C-arm CT as grade 1 (no additional information), grade 2 (added information without an effect on the treatment plan), or grade 3 (added information with an effect on the treatment plan). Tumor feeders and feeders of a systemic-to-pulmonary shunt were recorded.RESULTS: The information provided by C-arm CT was classified as grade 1 for nine of the 32 patients (28%), grade 2 for 20 patients (63%), and grade 3 for three patients (9%). The most common additional information from C-arm CT scans of the RIPA was the differentiation between the tumor and the systemic-to-pulmonary shunt. A systemic-topulmonary shunt from the RIPA was observed in 22 patients (69%), and the most common feeder of a systemic-topulmonary shunt was the azygoesophageal branch.CONCLUSIONS: C-arnt CT of the RIPA provides additional imaging information for the differentiation of a tumor from a nontumorous condition during chemoembolization for HCC with a suspected blood supply from an RIPA.
