摘　　要：目的 探讨多层螺旋CT血管造影（MSCTA）在肝癌介入治疗中的应用价值.方法 选择54例肝癌患者为研究对象,所有患者均行MSCTA检查,并进行图像后处理,观察肝癌的MSCTA特点,并与17例同期行数字减影血管造影（DSA）检查的肝癌患者进行对比,以分析MSCTA在肝癌介入治疗中的应用价值.结果 肝癌患者MSCTA动脉期均可见程度不同的肿瘤染色,2例肝动脉门静脉瘘；部分患者在门静脉期及肝静脉期见到静脉癌栓；MSCTA显示肝动脉变异10例,变异率为18.5％（10/54）,与DSA符合率为100.0％.MSCTA显示肝癌寄生动脉11支,1例DSA检查未发现,为右膈动脉供血的肝癌,两种方法显示肝癌寄生动脉比较差异无统计学意义（P＞0.05）.结论 MSCTA为一种微创伤的肿瘤血供诊断方法,可清晰显示肝动脉及其分支的起源与走行、肝癌的供血动脉、肝癌寄生动脉,与DSA显示结果高度一致,对肝癌介入治疗具有重要的指导意义.Objective To investigate the application value of multi-slice spiral CT angiography （MSCTA） in liver cancer patients interventional treatment.Methods Fifty-four liver cancer patients were selected,all patients underwent MSCTA examination,after the image post-processing,and with 17 cases of patients with the same period digital subtraction angiography （DSA） examination results for comparison,in order to analyze the application value of MSCTA in liver cancer patients interventional treatment.Results The patients with liver cancer were seen MSCTA arterial phase varying degrees of tumor staining,2 cases had hepatic arteriovenous fistula.Some patients in the portal vein and hepatic vein were found vein tumor thrombus.MSCTA showed 10 cases of hepatic artery variation,variation rate of 18.5% （10/54）,in line with the DSA rate of 100.0%.MSCTA showed 11 rami liver cancer parasitic artery,1 case of DSA was not found for the right phrenic artery of liver cancer,there was no significant difference in showed liver cancer parasitic artery between the two methods （P 〉 0.05）.Conclusion MSCTA as a minimally invasive diagnostic method of tumor blood supply,can clearly show the origin of the hepatic artery and its branches and walk the line,liver cancer feeding artery,liver cancer parasitic artery with DSA showed highly consistent results,interventional treatment of liver cancer with important guiding significance.
