摘要
目的:探讨冠状动脉-肺动脉瘘(CPF)的特征与超声心动图诊断方法。方法:回顾性对比分析16例CPF患者的临床及超声心动图数据,进行超声的漏诊分析和方法总结。结果:16例冠状动脉造影证实的患者中,左CPF 10例,左右CPF 5例,右CPF 1例。超声漏诊率虽然高达68.8%,但诊断出的5例均正确,特异性为100%,较好地显示了瘘入肺动脉的位置和瘘口大小、瘘管所属的冠状动脉。结论:多数CPF分流量较小,难以由超声心动图首先发现。但超声心动图诊断该病的特异性好,如果提高超声的诊断技巧,则可以提高检出率。
Objective： To discuss the features and diagnostic methods of echocardiography on coronary-topulmonary fistulae （CPF）. Method： The eehocardiographic data and findings of 16 patients with CPF were retrospectively reviewed and compared with clinical results in order to analyze the causes of omission and summarize the methods of echocardiography on CPF. Result： 16 cases were all confirmed by coronary arteriography. Among them, 10 cases were found to have left CPF, 5 cases with left and fight CPF and 1 case with fight CPF. The false negative rate of echocardiography on CPF was fairly high, up to 68.8%, but its specificity on CPF was 100%. That is, although only 5 cases were correctly diagnosed by ecbocardiography, each case of the five was described fairly accurately about the origin, position, and size of the CPF by echocardiography. Conclusion： Most CPF have small shunts, so their diagnoses by echocardiography are fairly difficult. But the specificity of echocardiography on CPF is high. If the diagnostic skills of echo- cardiography on CPF are enhanced, the detectable rate of it would also be elevated.
