Cerebral lipiodol embolism (CLE) is an extremely rare complication of transcatheter arterial chemoembolization for hepatocellular carcinoma. To our knowledge, only 11 cases have been previously reported. We recently encountered two cases of CLE in our clinical work. Reviewing the 11 cases in the literature and the two cases in our report indicates that large dose lipiodol infusion and absence of particulate embolization should be avoided. The presence of a right-to-left shunt and inferior phrenic artery injection seems to increase the risk of CLE. More caution should be taken in these situations.
脑内碘化油栓塞（CLE）是肝细胞癌经导管动脉化疗栓塞术的一种极罕见并发症。据我们所知，此前仅报道过 11 例。我们最近在临床工作中遇到了两例 CLE。回顾文献中的 11 例病例和我们报告的 2 例病例表明，应避免大剂量碘化油输注和无微粒栓塞。存在右向左分流和膈下动脉注射似乎会增加 CLE 的风险。在这些情况下应更加小心。
