目 的 探讨运用多层螺旋 CT(MSCT)诊断腹部假性动脉瘤(VAPA)的 临床价值及意义。方法 回顾性分析我院 2013年1月至2014年12月收治的怀疑患有 腹部假性动脉瘤的患者共42例，针对患 者进行MSCT的检查扫描，并经DSA进行确 诊，观察MSCT诊断VAPA的准确性及特征。 结果 42例患者中MSCT检查阳性为37例， 瘤体位置以腹主动脉为主(81.08%)，瘤体 大小以5-10cm为主(56.76%)。VAPA的临床 表现主要为腹痛、恶心呕吐、腹部搏动性 包块等，MSCT平扫时VAPA多出现密度不 均。运用MSCT诊断腹部假性动脉瘤与DSA 诊 断结果相比较，MSCT检验与金标准检 验方法(DSA检验)出VAPA结果比较无明显 差异(P＞0.05)。MSCT诊断VAPA的敏感性 为100%，特异性为83.33%，阳性预测值为 94.59%，阴性预测值为100%。结论 MSCT 较为直观有效的显示出MSCT的特征，对其 临床诊断和指导具有重要的价值，值得在 临床推广实施。

Objective Using multi-slice CT (MSCT) diagnosis of abdominal pseudoaneurysm (VAPA) the clinical value and significance. Methods Retrospective analysis of our hospital from January 2013 toDecember 2014 suspected abdominal pseudoaneurysm in patientsadmitted in 42 cases, Patient checks for MSCT scanning, And diagnosed by DSA, Observation of MSCT diagnosis accuracy of VAPA and features. Results MSCT in 42 patients were positive for 37 cases, Tumor location in abdominal aorta (81.08%),Tumor size in 5-10cm (56.76%).VAPA clinical manifestations were abdominal pain, nausea,vomiting, pulsatile abdominal mass, MSCT scan VAPA appear uneven density.Use of MSCT diagnosis of abdominal pseudoaneurysm with DSAdiagnosis compared, MSCT test and the gold standard testmethods (DSAinspection) to VAPA results showed nosignificant difference (P>0.05). VAPA MSCT diagnosissensitivity of 100%, a specificity of 83.33%, the positive predictive value of 94.59%, and negative predictive value of100%. Conclusion MSCT is more visually effective showing characteristics of MSCT, the clinical diagnosis and is of great value, andclinical implementation.
