【摘要】 本文应用超声技术对6例有此异常的患者进行探查分析,其中3例经手术证实。结合有关文献和作者所见,将此种变异分为三型,分析和探讨了各型的超声表现特征,并应用脉冲多普勒实时检测相应的血液动力学变化。初步提出了诊断和鉴别诊断要点。并认为在某些人此种变异易引致卵圆窝闭合延迟或与某些先天性心脏病并存,其超声表现又易与右房内肿块相混淆。另外,在进行临床听诊、心导管检查或外科手术时亦不应忽视其存在的影响。更多还原

【Abstract】 So far, 4ittle has yet been reported on the research of. permanent Eustachian valve remnant (PEVR) .In this article, six cases with PEVR are studied by applying ultrasonic technique, three of which being proved by surgical operations.Integrating the experience of relevant literature and of the writer’s own,we divide PEVR into three types, probe into the UCG feature of each, and suggest, on the basis of the real-time detection of the relevant change of the blood flow dynamics with the application of the pulse Doppler echocardiograph, the key-points of diagnosis and differential diagnosis. The writer holds that the importance of this article lies in, that, in some persons, the PEVR tends to lead to either delay closing of fossa ovalis or the combination with certain congenital heart diseases, while its UCG display is easy to be mixed with tumours in right atrium.Furthermore, the effect with PEVR must not be ignored while making clinical auscultation, cardiac catheterization, surgical operation, etc.更多还原
