摘　　要：目的将三维动态增强磁共振门静脉造影(3DDCEMRP)和动脉法间接门静脉造影(TAP)对照,评价细针脾穿刺CO2门静脉造影(CO2-SP)的临床应用价值。资料与方法35例接受了以上3种方法门静脉造影。对照分析CO2-SP、3DDCEMRP和TAP对门静脉的显示能力,包括:(1)门静脉成像质量;(2)门静脉主干及左、右分支的开放性;(3)侧支循环发生的部位及分布的范围。结果CO2-SP、3DDCEMRP和TAP门静脉显影质量的平均得分分别为6.46±1.68、5.60±1.55、4.77±1.61,方差分析三者之间的差异有统计学意义(F=9.49,P<0.05)。3种方法显示门静脉开放性的差异无统计学意义(卡方检验,P>0.05),不一致主要表现为显示门静脉开放性程度不同。对侧支循环显示率分别为97%、92%和70%,χ2检验三者之间的差异有统计学意义(χ2=14.92,P=0.001)。结论CO2-SP显示门静脉的图像质量优于3DDCEMRP和TAP;CO2-SP能够准确显示门静脉开放性及侧支循环,尤其在门静脉狭窄程度及细小侧支循环方面具有更强的显示能力。Objective To evaluate the clinic value of CO2 splenoporgraphy （CO2-SP） and compare with 3 dimensional dynamic contrast enhanced magnetic resonance portography （3D DCE MRP） and transarterial portography （TAP）. Materials and Methods 35 patients were performed with three kinds of portography. The clinical values of CO2-SP, 3D DCE MRP and TAP were analyzed and compared, included： （1） The imaging quality of portal vein; （2） The patency of the portal vein; （3） The distribution and extent of collateral vessels, Results The mean score of imaging quality of the portal vein shown by CO2-SP, 3D DCE MRP and TAP were 6.46 ± 1.68, 5.60 ± 1.55 and 4.77 ± 1.61 respectively （ F = 9.49, P 〈 0.05 ）. There were no significant differences of the patency of the portal vein shown by three kinds of portography （X^2 test, P 〉 = 0.05 ）. The discordant findings mainly reflected the discrepancy of the degree of patency of portal vein. Collateral vessels displayed by CO2-SP, 3D DCE MRP and TAP were 97 %, 92 % and 70 % respectively, and the difference between three kinds of portography was significant （X^2 = 14.92, P = 0.001 ）. Conclusion The imaging quality of portal vein with CO2-SP is superior to that with 3D DCE MRP and TAP; CO2-SP can accurately display the portal veins patency and existence of varices, in addition, it has stronger ability in revealing the degree of the portal veins stenosis and small collateral vessels.
