摘　　要：目的探讨数字减影血管造影(DSA)在射频切除(radiofrequency ablation,RFA)肝脏恶性肿瘤中的作用。方法通过65例肝脏恶性肿瘤射频切除后DSA检查,观察其在RFA疗效评价中的作用。结果 33例显示新生肿瘤血管及肿瘤染色消失,瘤区显缺损状态,注入超薄碘油乳剂无聚集;32例显示新生肿瘤血管及肿瘤染色仍较丰富,中央显缺损区,周边见多处肿瘤血管及肿瘤染色残留,注入超薄碘油乳剂见团状、片状、月亮型或环圆状聚集。结论 DSA在RFA中可直接了解新生肿瘤血管及肿瘤染色变化情况,是RFA可靠的疗效评价指标。Objective To study on the role of digital subtraction angiography (DSA) in evaluation of the therapeutic efficacy of radiofrequency ablation( RFA) in treatment of the liver malignant tumors. Methods Sixty-five cases of liver malignant tumors were treated with RFA. The role of DSA in evaluation of the therapeutic efficacy of RFA was observed. Results In 33 patients after RFA, the vascularity and staining of the tumors disappeared. The zones of tumors had no vascularity, and no collection of lipiodol injected. In 32 patients after RFA, the tumors were still rich in vascularity and staining, especially around the masses, and the lipiodol injected accumulated as rumps,flakes,moon-shaped and ring-shaped masses. Conclusion The results indicate that DSA is a reliable method for evaluating the therapeutic efficacy of RFA. It can directly evaluate the changes of the vascularity and staining of the tumor after RFA.
