目的 重视操作技术在肝癌肝动脉栓塞化疗术中的作用。方法 使用DSA对 5 4例肝细胞癌作 1 6 2疗次的经导管动脉碘油化疗栓塞术。肿瘤缩小率根据CT之测量获得。所有病人均随访 1年以上。结果 发现 1 3例治疗效果欠佳与操作因素有关。其一未能及时发现膈下动脉供血6例 ,是因肝癌巨大、供血丰富而又未加作腹主动脉造影所致 ;其二HCC患者在首次或第 2疗次后肝动脉呈现严重狭窄 /闭塞 7例 ,原因可能为导管先端的机械性损伤和化疗药物的化学刺激所致。 1 3例的肿瘤缩小率与对照组比较有显著性差异 (P <0 0 1 )。结论 规范的操作技术可以提高TOCE疗效。
Objective To emphasize the role of operative technique in hepatic arterial chemoembolization of liver cancer. Methods 54 cases of hepatocellular carcinoma were treated with DSA for 162 cycles of transcatheter arterial iodine chemoembolization. The rate of tumor shrinkage was measured by CT. All patients were followed up for more than 1 year. The results found that 13 cases of poor treatment and operational factors. One of the failed to detect subphrenic arterial blood supply in 6 cases, due to a huge liver, rich in blood supply without additional abdominal aortography; the second HCC patients after the first or second treatment of the hepatic artery showed severe stenosis / Occlusion in 7 cases, the reason may be a mechanical catheter tip injury and chemotherapy drugs caused by chemical irritation. Thirteen cases of tumor shrinkage rate compared with the control group were significantly different (P <0.01). Conclusion The standard operation technique can improve the efficacy of TOCE.
