Computed Tomography Angiography Imaging of the Ductus Arteriosus Aneurysm in a Neonate

Ductus arteriosus aneurysm (daa) is a rare and fatal abnormality. pulmonary hypertension, refractory heart failure and left ventricular loading developed in a 6-day-old female neonate diagnosed with transient tachypnea of the newborn (ttn). in the echocardiography, aortic arc abnormality and ductus arteriosus aneurysm (daa) was suspected. computed tomography angiography (cta) was performed to prove the diagnosis. in the cta, an aneurysmatic dilatation was observed in the ductus arteriosus and an aneurysectomy was performed surgically. to the best of our knowledge, the present study is the second case of pulmonary hypertension due to daa in the english literature. in this case report, we aim to emphasize the contribution of cta to the diagnosis of daa.
