摘　　要：目的：研究经肠系膜上动脉门脉造影ＣＴ（ＣＴＡＰ）在评价肝癌患者的门静脉血流方面是否优于经肠系膜上动脉门脉造影（ＳＭＡ－Ｐ）。方法：２１例肝癌患者在血管内治疗前先后行ＣＴＡＰ及ＳＭＡ－Ｐ，进行对比研究。结果：１３例ＣＴＡＰ与ＳＭＡ－Ｐ评价结果一致；７例评价结果基本一致，其中６例由于碘油重叠或血液层流ＳＭＡ－Ｐ显示欠佳者ＣＴＡＰ都能清晰显示，其中１例段级门脉阻塞，ＣＴＡＰ显示更确切的解剖部位；１例评价结果不一致，门脉高压影响ＳＭＡ－Ｐ对门脉的显示，但ＣＴＡＰ仍能清晰显示。结论：ＣＴＡＰ较ＳＭＡ－Ｐ能更准确地反映肝癌患者的门脉血流。Objective:To determine if CT during arterial portography (CTAP)is more accurate than arterial portograhy via the superior mesenterior atrtery(SMA-P)in evaluating the status of the patients with hepatocellular carcinoma.Methods:Both CTAP and SMA-P were performed in 21 patients with hepatocelluar carcinoma prior to transcather arterial therapy.Results:CTAP was in concert with SMA-P in 13 patients.CTAP showed more accurate than SMA-P in 7 patients,in 6 of which some branches of portal vein didn′t show clearly in SMA-P due to laminar flow or the overlap of the lipiodol,and in another patient with segmental occulusion CTAP showed the anatomy location more accurate than SMA-P.1 patient CTAP showed the intrahepatic portal blood flow clear but SMA-P didn′t show successfully due to portal hypertention.Conclusion:Our study suggests that CTAP is more accurate than SMA-P in evulating the intrahepatic portal blood flow in patients with hepatocelluar carcinoma.
