Abstract:
Objective To investigate the application of echocardiography in the diagnosis of neonatal ductus arteriosus aneurysm (DAA).Methods A total of 27 neonates with DAA were detected by echocardiography.Echocardiographic features in these cases were explored and outcome of these neonates were followed up.Results There were four crucial features in DAA detected by echocardiography:① A vessel bump was shown on the left side of the origination of left pulmonary artery(LPA) in the high parasternal short-axis view.②A horizontal shunt jet from the bump to the origination of LPA was shown when interrogate the top of the bump.③The bump joined the descending arota when interrogate it down and back orientately.A ‘V' shaped sign was shown when the aortic arch appeared on the right side and the bump on the left side.④A slow red flow signal was found in bump when the scale of color Doppler was cut down.The follow-up echocardiography showed spontaneous closure of the DAA when 3 months of age except one case lost.There were no abnormality in the figure and function in heart.Conclusions Echocardiography can be a valuable method for the diagnosis of neonatal ductus arteriosus aneurysm.Neonate with DAA have a good outcome.
