经食管超声诊断胸主动脉疾病

Diagnosing thoracic aortic diseases by transesophageal echocardiography

报道对临床疑诊胸主动脉疾病而行食管超声（ＴＥＥ）检查的患者共４７例，ＴＥＥ诊断主动脉夹层１８例，主动脉扩张１５例，正常９例，其它５例。通过分析胸主动脉疾病的ＴＥＥ诊断特征，并与手术结果、减数血管造影及磁共振成象进行对比研究，结果显示ＴＥＥ在胸主动脉疾病诊断中具有重要、独特的价值。

Abstract Forty seven patients suspected to have aortic diseases were studied by transesophageal echocardiography (TEE).Aortic dissection was identified in 18 patients,aortic dilation in 15 patients,and 9 patients in whom aortic disease was not found.Comparing with DSA,MRI and surgical findings,we found that TEE is a sensitive and convenient method for the definitive diagnosis of thoracic aortic disease.There were 2 cases of aortic dissection which was correctly dignosed by TEE and missed by DSA or MRI in the present study.
