对４６例原发性肝癌患者ＬＰＴＡＥ术前后行ＣＴ及彩色多普勒超声（ＣＤＦＩ）检查，了解ＬＰＴＡＥ术前肿瘤内血供情况、肝动脉的血流速度、术后肿瘤内的药物存留情况及肿瘤缩小程度和术后肿瘤的血供恢复情况，并将ＣＴ、ＣＤＦＩ的资料进行对比。结果：ＣＤＦＩ对了解肝癌的血供情况优于ＣＴ，ＣＴ对术后肿瘤内碘油存留情况优于ＣＤＦＩ。提示：ＣＤＦＩ对ＬＰＴＡＥ术前碘油用量及疗效有较好的预见性，对肝癌患者再次行ＬＰＴＡＥ术时机的选择有较好的指导作用；而ＣＴ对肝癌患者的ＬＰＴＡＥ术后疗效观察较之ＣＤＦＩ更有意义。
The CT and color Doppler ultrasound (CDFI) examinations were performed before and after LP TAE in 46 patients with primary liver cancer. The preoperative intratumoral blood supply, blood flow velocity of the hepatic artery, and postoperative intratumoral tumor were studied. The drug retention and tumor shrinkage and blood supply recovery after surgery were compared, and CT and CDFI data were compared. RESULTS: CDFI was superior to CT in understanding the blood supply of liver cancer. CT was superior to CDFI in the retention of lipiodol in postoperative tumors. Tip: CDFI has a good predictability of lipodol consumption and curative effect before LP TAE, and has a good guiding role in the selection of timing of LP TAE for patients with liver cancer; and CT for LP TAE in patients with liver cancer. After-effect observation is more meaningful than CDFI.
