摘　　要：目的探讨两种碘浓度对比剂对B型主动脉夹层(aortic dissection,AD)旋转血管造影图像质量的影响。方法回顾性分析广东省人民医院2011年1月至2012年7月157例B型AD患者的主动脉旋转血管造影图像资料,其中应用370 mg I/m L对比剂71例,应用320 mg I/m L对比剂86例,以相同注射流率行主动脉旋转造影,并以夹层累及范围、头臂血管分支及受累情况、破口大小及位置的显示情况对图像进行评分及统计分析。结果主动脉旋转血管造影对AD的细节显示良好,两种不同碘浓度的对比剂在造影图像质量上比较,差异无统计学意义(P>0.05)。结论主动脉夹层旋转血管造影时,应用370 mg I/m L与320 mg I/m L对比剂在注射流率相同的情况下,均能满足诊断和介入需求,可根据临床需要选择合适的对比剂进行检查,以减少对比剂的毒副作用。Objectives To compare the effects of two iodine concentrations of contrast media [370 mg I/mL and 320 mg I/mL] on the image quality of rotational angiography in aortic dissection.Methods From January 2011 to July 2012,clinical data of 157 cases with aortic dissection （Stanford type B） receiving rotational angiography in Guangdong General Hospital were reviewed and analyzed.Of these patients,71 cases received 370 mg I/mL concentration contrast media and 86 received 320 mg I/mL with the same flow rate.SPSS 19.0 was used to compare the image quality by the two iodine concentrations of contrast media.Results The difference in image quality between the two iodine concentrations of contrast media on rotational angiography in aortic dissection was not statistically significant （P＞0.05）.Conclusions There is no obvious difference in image quality between 370 mg I/mL concentration contrast media and 320 mg I/mL concentration contrast media on rotational angiography in aortic dissection with the same flow rate.Therefore,we can choose one of them for rotational angiography in aortic dissection according to the clinical status of patients,in order to reduce the side effects.
