彩色多普勒超声诊断动脉导管未闭的体会(附78例报告)

Diagnosis of patent ductus arteriosus with color Doppler ultrasound: a report of 78 cases

目的通过78例动脉导管未闭(PDA)患者的检查,研究彩色多普勒超声对动脉导管未闭的诊断价值。方法取大血管短轴及胸骨上窝主动脉弓长轴切面确定有无PDA,多切面观察有无合并畸形,并与手术结果进行对照。结果78例中,PDA合并其它畸形15例,占19.2%,PDA合并Eisnmenger's综合征1例,占1.3%,同时发现,导管直径与左房室腔大小成正相关关系。结论彩色多普勒超声是诊断PDA的首选方法,且可及时发现合并畸形,为临床选择治疗方案提供确切的依据。

Objective To determine the value of color Doppler ultrasound in the diagnosis of patent ductus arteriosus(PDA).Methods Seventy-eight patients with PDA underwent the examinations of color Doppler ultrasound before the operation or interventional treatment.In order to observe whether PDA complicated with other malformation,the short axis of large vessel and the long axis of aortic arch in superior fossa of sternum were taken as the detective section and then those findings seen on multiplane were compared with surgical findings.Results Among 78 patients with PDA,15 cases(19.2 %) complicated with other malformations,one case(1.3 %)complicated with Eisnmenger′s syndrome,at same time,the diameter of PDA was found to be directly proportional to the size of left atrioventricular cavity.Conclusion Color Doppler ultrasound may become a method of first choice for PDA because it can not only detect PDA complicated with other malformations but can provide the reliable evidences for establishing treatment protocol.
