摘　　要：目的:探讨肝动脉数字减影术(DSA)及CT增强在肝癌术后患者复查中的应用价值。材料与方法:收集肝癌手术切除术后的患者28例,该组患者均行肝动脉造影,其中18例行CT增强扫描,综合其临床资料,总结其DSA及CT增强表现特点,并与最终确认复发者进行比较,分析其相互关系。结果:28例肝癌术后患者中最终确诊复发者25例,复发病人中,DSA显示异常者23例,CT增强检查者中最终确诊复发者17例,CT增强显示异常者12例。结论:肝脏DSA检查对于肝癌术后复发的诊断具有较高的灵敏度和特异度,肝癌术后患者宜常规行DSA检查。Purpose：To discuss the diagnostic value of DSA for the recurrence of liver cancer after surgery.Materials and Methods：The DSA data of 28 postoperative patients with hepatocarcinoma were collected,which 18 of them performed contrast-enhanced CT study.The DSA and CT features integrated clinical materials were analyzed and then cpmpared with final diagnosis.Results：25 cases of tumor recurrence were found in the 28 liver cancer patients after operation,in which 23 cases were found by DSA and 12 cases were found by contrast-enhanced CT.Conclusion：The liver DSA examination showed higher sensitivity and specificity in the diagnosis of recurrence of liver cancer after operation and the DSA examination should be carried routinely after surgery.
