摘　　要：目的探讨肝癌经动脉穿刺化疗栓塞(transcatheter arterial chemoembolization,TACE)治疗后肝内胆汁瘤形成的CT表现和临床意义。方法搜集我院2000年至2004年经CT检查系列随访的肝癌TACE后患者共3948例。观察TACE术后有无胆管阻塞和扩张等表现。结果共发现35例(0.9%,35/3948)胆汁瘤,其中沿Glisson鞘呈分支样分布的低密度区4例,残癌病灶周围柱状改变7例,囊状改变33例。结论胆汁瘤是肝癌介入治疗后并发症之一,随病情进展可以有不同CT表现。治疗上可采取以内科保守治疗为主的多种方法。Objective The purpose of our study was to discuss the incidence, CT findings, and clinical course of intrahepatie biloma after transeatheter arterial ehemoembolization for hepstoeellular carcinoma. Methods Three thousand and nine hundred forty-eight patients with hepatoeellular carcinoma （n = 3948 ） underwent chemoembolization during a 4-year period beginning in September 2000. We retrospectively reviewed the medical records and follow-up CT and analyzed the factors associated with the formation of intrahepatic biloma. Results intrahepatic biloma developed after chemoembolization in 35 patients （0. 9%, 35/3948） in our series. Thirty-three of them displayed cystic lesions, 7 displayed columnar dilation and 4 showed branching appearance of hypoattenuating area along the Glisson＇s sheath. Conelution intrahepatic biloma formation is one of the major complications after transeatheter arterial ehemoembolization. Different CT findings can be detected due to different phases in the disease＇s course. Conservative medieational therapy is the recommended treatment.
