摘　　要：目的　评价旋转DSA(RDSA)在节段性肝动脉化疗栓塞治疗肝癌中的应用价值。方法　 3 0例拟行节段性肝动脉栓塞的肝癌患者 ,TACE之前行常规DSA和RDSA肝动脉造影。对两种方法显示肝动脉分支、肿瘤供血动脉及肿瘤血管结构等情况做对比观察 ,进行 χ2 检验。结果　常规DSA在整体图像质量和显示肿瘤血管染色方面优于RDSA ;而RDSA显示能够独立分辨的肝亚段动脉及肿瘤供血动脉的能力则明显超过常规DSA(P <0 .0 0 1)。结论　RDSA在显示肝亚段动脉分支和明确肿瘤供血动脉方面具有明显优势 ,与传统DSA结合使用有助提高肝癌TACE治疗的质量。Objective To evaluate the usefulness of rotational digital subtraction angiography (RDSA) on segmental transarterial chemoembolization (S-TACE) for HCC.Methods Conventional DSA and RDSA were performed in sequence on 30 patients with HCC who were going to receive S-TACE.Angiographic differences between the two methods in demonstrating sub-segmental branches of hepatic artery,tumor feeding arteries and tumor stain were observed and analyzed with χ 2 test.Results General image quality was better and angiographic details of tumor were more clear in conventional DSA,whereas RDSA has a significant higher ability to show the differentiable branch of sub-segmental hepatic artery and tumor feeding artery ( P <0.001).Conclusion RDSA has the advantage in demonstrating the sub-segmental hepatic artery branch and tumor feeding artery.Combined application of RDSA with conventional DSA will help to improve TACE efficiency.
