【摘要】 为探讨经食管超声心动图（ＴＥ｀Ｅ）对升主动脉扩张疾病的诊断价值，４６例经胸超声心动图（ＴＴＥ）诊断为升主动脉扩张的患者进行了ＴＥＥ的研究。结果表明：（１）ＴＥＥ能清晰显示的升主动脉长度明显高于ＴＴＥ（Ｐ＜０．００１）；（２）ＴＥＥ和ＴＴＥ对升主动脉内径的测值无显著性差异（Ｐ＞０．０５）；（３）ＴＥＥ对升主动脉扩张疾病的病因诊断率（９３．５％）明显高于ＴＴＥ（７３．９％）（Ｐ＜０．０５）；（４）ＴＥＥ能够确定９７．８％的患者的升主动脉的病变范围，而ＴＴＥ仅能确定１７．８％的患者的病变范围（Ｐ＜０．０１）。ＴＥＥ对动脉粥样硬化斑块的检出率也明显高于ＴＴＥ（Ｐ＜０．０１）。因此，我们认为：对于升主动脉扩张，ＴＥＥ是一种十分安全、有效的诊断技术，应作为常规使用。更多还原

【Abstract】 To evaluate the diagnostic value of transesophageal echocardiography(TEE)to ascending aorta distension 46 patients with ascending aorta distension patients diagnosed by transthoracic echocardiography(TTE)were reviewed with TEE.The results showed that(1)The length of ascending aorta observed with TEE was apparently longer than that of with TTE(P<0.001).(2)The measuring values of TEE and TTE to inner diameter of ascending aorta were similar(P>0.05).(3)The etiological diagnosis rate of TEE to ascending aorta distension(93.5%)was much higher than that of TTE(73.9%).(4)The diseased scopes of ascending aorta can be determined by TEE in 97.8%patients,but by TTE in 17.8%(P<0.01).The TEE detecting atherosclerosis plaques rate was apparently higher(P<0.01).更多还原
