64排螺旋 CT 血管成像对腹主动脉瘤血管评价的应用

目的：探讨64排螺旋 CT 血管成像技术在腹主动脉瘤中的诊断及术前应用价值。方法将我院采用64排螺旋 CT 血管成像技术检查并疑似为腹主动脉瘤的53例患者进行高浓度碘对比剂血管造影检查,观察64排螺旋 CT 血管成像技术诊断的准确性。观察患者的病变累及部位、类型、大小及范围,并根据腔内隔绝术的要求对腹主动脉瘤患者进行测量和分型。结果全部患者中近肾型、肾下型、肾上型分别占11.3%(6/53)、83.0%(44/53)、5.7%(3/53)；64排螺旋 CT 检查结果准确率达96.2%,与“金标准”相比,具有相关性(r =0.9983,P <0.05)；依据三型五分法,Ⅰ型4例(7.6%,4/53)、ⅡA 型7例(13.2%,7/53)、ⅡB 型5例(9.4%,5/53)、ⅡC 型26例(49.1%,26/53)、Ⅲ型9例(17.0%,9/53)。结论64排螺旋 CT 血管成像技术具有快速、简便、精确性高的特点,是 AAA 诊断及术前评估的首选方法。

Clinical application of 64-slice spiral CT angiography in evaluation of abdominal aortic aneurysm

Objective To investigate the diagnosis and preoperative application of 64-slice CT angiography in abdominal aortic aneurysm.Methods Fifty-three patients in the hospital after using 64-slice spiral CT angiography examination and suspected abdominal aortic aneurysms got high concentrations of iodine contrast agent angiography to evaluate the the diagnosis accuracy.The patients were detected for the lesion location,type,size and scope,and in accordance with the requirements of endovascular abdominal aortic aneurysm,the patients were measured and typed. Results All patients with near kidney type,under kidney type,above kidneytype accounted for 11.3%（6/53）,83.0%（44/53）,5.7%（3/53 ）;64-slice spiral CT proved accuracy rate 96.2%,compared with the gold standard,statistic correlation existed,the correlation coefficient （r =0.9983,P 〈0.05）;based on three types and five points method,Ⅰ type 4 cases （7.6%,4/53 ）,Ⅱ A in 7 cases （13.2%,7/53 ）,Ⅱ B in 5 cases （9.4%,5/53 ）,Ⅱ C type 26 cases （49.0%,26/53 ）,Ⅲ 9 cases （1 7.0%,9/53 ）.Conclusion 64-slice CT angiography has fast,simple,high precision characteristics,and the method is the preferred method in diagnosis and preoperative assessment of abdominal aortic aneurysm.
