摘　　要：目的　评价磁共振血管成像 (MRA)、彩色多普勒血流显像 (CDFI)及间接门脉数字减影血管造影 (DSA)在门静脉高压症门脉系统及门体侧支循环显像中的应用和三者优缺点比较。方法　 32例该症病人接受了MRA检查 ,2 0例病人分别行CDFI和DSA检查。结果　MRA对胃左静脉侧支 (LGV)、胃短静脉侧支 (SGV)、开放脐静脉侧支 (UV )、自发脾肾静脉分流侧支、胃后静脉侧支 (PGV )及腹膜后交通侧支的检出率分别为 93 .75 %、87.5 %、6 .2 5 %、15 .6 2 %、37.5 %和 2 8.13 % ,其中 1例合并门脉主干 (MPV )栓塞 ;CDFI对LGV、SGV、UV诸侧支的显示率分别为 80 %、5 %、10 % ,1例合并脾静脉栓塞 ,另 1例合并MPV海绵样变 ;间接门脉DSA对前述侧支的显示率分别为 80 %、45 %及 2 5 %。结论　MRA能更全面、准确地了解门脉系统及门体侧支循环的建立情况。Objective To evaluate the application of MRA (Magnetic resonance angiography), CDFI (Color doppler flow image) and indirect portal vein DSA (Digital subtraction angiography) in display of portal system and shunt branch in portal hypertension patients.Methods 32 cases of portal hypertension underwent MRA examination and 20 cases were subject to the examination of CDFI and indirect portal DSA respectively.Results In all cases underwent MRA examination, 93.75% LGV (Left gastric vein), 87.5% SGV (Short gastric vein), 6.25% open UV (Umbilical vein) shunt, 15.62% spontaneous spleen renal shunt branches, 37.5% PGV (Post gastric vein) and 28.13% post peritoneal shunt branches were displayed, with one case of main portal vein embolism discovered; CDFI displayed 80% LGV, 5% SGV and 10% open UV shunt, with the discovery of one case of spleen vein embolism and one case of MPV (main portal vein) spongiformation; the display rate of indirect DSA to LGV, SGV and open UV shunt was 80%, 45% and 25% respectively.Conclusion MRA contributed to the understanding of portal vein system and shunt branches with a more comprehensive and informative display.
