超声心动图对早期诊断婴幼儿动脉导管未闭的临床价值

Clinical value of Echocardiography in early diagnosis of infants and young children patent ductus arteriosus

目的:评价超声心动图对早期婴幼儿动脉导管未闭诊断价值。方法:选择年龄为出生24h^1.5岁的:选择年龄为出生118例临床疑诊为动脉导管未闭(PDA)的婴幼,均于体检时临床听诊有心前区心脏杂音。在3~5天临床药物治疗后,再次或三次复查心脏超声,动态观察新生儿动脉导管关闭情况。结果:在118例疑诊动脉导管未闭的婴幼儿,76例单纯性PDA,18例PDA合并肺动脉高压,3例PDA合并肺动脉瓣狭窄,2例PDA合并室间隔缺损,16例PDA合并房间隔缺损,3例PDA合并肺动脉瓣闭锁。经过3~5天临床药物治疗后,复查心脏超声发现婴幼儿动脉导管多数可自然关闭。可自然关闭。结论:对疑诊动脉导管未闭的婴幼儿进行心脏超声心动图检查,可以明确心脏杂音的产生原因,同时进行临床药物治疗,动态检测动脉导管的关闭时间,对诊断PDA具有重要价值。

Objective To evaluate the diagnostic value of echocardiography in early infants and young children patent ductus arteriosus.. Methods Methods 118 cases of clinically suspected infants and young children's born age was 24 h ~ 1.5 years, which had heart murmurs in medical clinical auscultation area. In clinical drug treatment 3 to 5 days, echocardiography was rechecked after three times again, and the dynamic observation of neonatal arterial catheter closure. s again, and the dynamic observation of neonatal arterial catheter closure. Results Results In 118 cases of clinical suspected patent ductus arteriosus infants and young children, there was 76 cases of simple PDA, 18 cases of PDA merge pulmonary hypertension, 3 cases of PDA combined pulmonary stenosis, 2 cases of PDA with ventricular septal defect, 16 cases of PDA merger atrial septal defect, 3 cases of PDA combined pulmonary atresia. After 3 to 5 days of clinical drug therapy, we found that the many infants artery catheter can be shut down naturally. n be shut down naturally. Conclusion Conclusion History artery catheter no closed of infants and young children by heart echocardiography can clear heart murmur of reason, for clinical drug treatment at the same time, the dynamic testing arterial catheter closing time, which has important value for diagnosis of PDA.
