摘要
目的:通过与常规门静脉直接造影(CP)的比较,评价CT门静脉成像(CT portography,CTP)显示食管胃静脉曲张相关侧支循环血管的能力。方法:对42例门静脉高压食管胃底静脉曲张栓塞术患者的术前CT门静脉成像和术中常规门静脉直接造影进行对比,比较二者对食管胃静脉曲张相关侧支血管显示的差异性,采用卡方检验。结果:二种检查方法对食管胃静脉曲张相关侧支血管显示的差异性检验,(χ2=2.00,P>0.05),表明二者无显著差异。结论:CT门静脉成像能直观显示食管胃静脉曲张相关的侧支循环血管,有助于治疗方案的选择和缩短治疗的时间。
Objective:To evaluate the accuracy of CT portography(CTP) in demonstration of gastroesophageal varices and their related collateral vessels by correlating with conventional portography(CP).Methods:Contrasting CTP and CP of 42 patients with gastroesophageal varices underwent interventional embolism.χ^2 test was used to detect the differences of CTP and CP demonstrating the collateral vessels of gastroesophageal varices.Results:According to χ^2 test,CTP and CP had no significant differences in demonstrating the related collateral vessels(χ^2=2.00,P〉0.05).Conclusion:CTP can instuitively demonstrate the related collateral vessels of gastroesophageal varices,which makes it easier to select therapeutic regimen and shorten therapeutic time.
