超声心动图与CTA对主动脉夹层诊断价值的分析

目的探讨超声心动图及CTA对主动脉夹层的诊断价值。方法收集自2014年5月至2016年5月在我院经手术确诊的51例主动脉夹层病例,术前均做过超声心动图及CTA检查的病例进行分析,评价两种影像检查方法在主动脉夹层诊断中的价值。结果本组51例患者中,De BakeyⅠ型的病例有14例,De BakeyⅡ型的病例有4例,De BakeyⅢ型的病例有33例。超声心动图对所有病例的检出率是90.2%(46/51),而CTA对所有病例的检出率是96.1%(49/51),两者比较差异无统计学意义(P0.05)。超声心动图漏诊的5例病例中,1例是De BakeyⅠ型,4例是De BakeyⅢ型;CTA漏诊的2例病例均是De BakeyⅡ型的。结论心脏超声及CTA检查作为两个独立的检查手段对主动脉夹层的诊断具有非常重要的价值,在实际工作中将两者联合使用必将提高对主动脉夹层的诊断水平,为临床医生提供更为准确的治疗参考。

Transthoracic Echocardiography and CTA Analysis of Diagnostic Value of Aortic Dissection

Objective To explore the value of transthoracic echocardiography (TTE) and CTA in the diagnosis of aortic dissection. Methods Collected 51 cases of aortic dissection confirmed by surgery in our hospital from May 2014 to May 2016 , preoperative are done cases of echocardiography and CTA examination were analyzed, and the evaluation of two methods of imaging in the diagnosis of aortic dissection. Results 51 cases patients, DeBakey typeⅠcases have 14, DeBakey typeⅡcases have 4, DeBakey type Ⅲ cases with 33. Echocardiography detection rate was 90.2% (46/51) of all cases, the CTA for all case detection rate was 96.1% (49/51), compare the differences between no statistical significance (P>0.05). Echocardiography in diagnosis of 5 cases, 1 case was DeBakey typeⅠ, 4 cases is DeBakey typeⅢ. CTA in diagnosis of 2 cases were DeBakey typeⅡ. Conclusion Transthoracic echocardiography and CTA inspection as two independent method has very important value to the diagnosis of aortic dissection, in the actual work will be a combination of both will improve the level of the diagnosis of aortic dissection and reference for clinical doctors to provide more accurate treatment.
