Abstract

INTRODUCTION AND OBJECTIVE

Eighty-two patients with suspected aortic dissection were studied to assess the usefulness of transesophageal echocardiography in the diagnosis of this entity.

METHODS

All patients underwent transesophageal echocardiogram. The diagnosis of aortic dissection was established in 46 patients by other diagnostic procedures including angiography and computed tomography, surgery and necropsy.

RESULTS

The sensitivity and specificity of transesophageal echocardiography were 98% and 97%, respectively. By computed tomography, sensitivity was 92% and specificity 88%. By angiography, sensitivity and specificity were 97% and 93%, respectively. In the diagnosis of the dissection type, transesophageal echocardiography classified correctly in 98%, computed tomography in 89% and angiography 97% of cases. Transesophageal echocardiography visualized the tear in 82% of cases, and angiography in 53%.

CONCLUSIONS

Transesophageal echocardiography provides rapid, accurate diagnosis of aortic dissection and permits the initiation of appropriate treatment. Angiography is indicated in non-conclusive cases or those which supra-aortic involvement clinically suspected.

摘要

引言与目的

对82例疑似主动脉夹层的患者进行研究，以评估经食管超声心动图在该疾病诊断中的作用。

方法

所有患者均接受经食管超声心动图检查。46例患者通过包括血管造影、计算机断层扫描、手术及尸检等其他诊断方法确诊为主动脉夹层。

结果

经食管超声心动图的敏感性和特异性分别为98%和97%。计算机断层扫描的敏感性为92%，特异性为88%。血管造影的敏感性和特异性分别为97%和93%。在夹层类型的诊断中，经食管超声心动图正确分类的病例占98%，计算机断层扫描为89%，血管造影为97%。经食管超声心动图在82%的病例中显示出撕裂口，血管造影为53%。
