肝动脉碘油栓塞后瘤周门脉碘油逆流的表现

Manifestation of lipiodol overflow into portal veins surrounding tumors during transcatheter arterial embolization for hepatocellular carcinoma

目的 :探讨肝动脉碘油栓塞后肿瘤周围门脉碘油逆流的表现。方法 :选取 5 0例肝动脉栓塞后腹部平片显示瘤周门脉碘油逆流 ,分析瘤周门脉碘油逆流的形态。结果 :瘤周门脉逆流为肿瘤周围的 3～ 5级门静脉分支碘油显影 ,可表现为肿瘤周边较粗的血管分支或星状小血管分支碘油显影。结论 :作者认为肿瘤周围出现门脉碘油逆流是肿瘤碘油栓塞完全的标志之一 。

Objective: To evaluate the manifestation of lipiodol overflow into portal veins surrounding tumors during transcatheter arterial embolization for hepatocellular carcinoma. Methods: 50 cases of manifestation (by plain abdominal radiograph) of lipiodol overflow into portal veins surrounding tumors during transcatheter arterial embolization for primary hepatocellular carcinoma are analyzed. Results: The lipiodol overflow into portal veins is developed,it may manibested in relatively large vessels or “star like”small vessels surrounding the lesions development by lipiodol. Conclusion: The authors suggested that lipiodol overflow into portal veins was one of the markers of complete embolization for tumors, and it may play a partial role in embolizing the portal venous supply for hepatocellular carcinoma.
