目的:探讨彩色多普勒超声在动脉导管未闭(PDA)及其合并心内畸形诊断中的价值。方法:应用彩超对99例PDA患者进行检测,其中26例经手术证实。常规测量各房室腔大小,重点观察主肺动脉和左肺动脉与降主动脉间的沟通情况,检测导管的大小、部位,分析PDA及其并发心内畸形的超声表现。结果:本组PDA经手术证实的1例漏诊。单纯性PDA者占36%(36/99),合并其它心内畸形者占63%(63/99)。VSD、ASD、肺动脉狭窄是PDA最为常见的并发畸形。结论:彩色多普勒超声能够准确地诊断PDA,并能检出其合并的心内畸形,具有很高的临床应用价值。
Objective: To investigate the value of color Doppler ultrasound in the diagnosis of patent ductus arteriosus (PDA) and its associated intracardiac deformity. Methods: 99 cases of PDA were detected by color Doppler ultrasound, of which 26 cases were confirmed by surgery. The size of each atrioventricular cavity was routinely measured. The communication between the main pulmonary artery and the left pulmonary artery and the descending aorta was observed. The size and location of the catheter were detected. The ultrasound findings of the PDA and its intracardiac deformity were analyzed. Results: This group of PDA confirmed by surgery in 1 case missed diagnosis. Simple PDA accounted for 36% (36/99), combined with other heart malformations accounted for 63% (63/99). VSD, ASD, pulmonary stenosis is the most common PDA deformity. Conclusion: Color Doppler ultrasound can accurately diagnose PDA, and can detect its combined intracardiac deformity, with high clinical value.
