Transthoracic echocardiography of the double aortic arch in a newborn
Double aortic arch constitutes about 46–76% of all symptomatic congenital vascular rings, and usually appears in the first months of life. The vascular ring, formed by two functioning arches, tightly covers the trachea and esophagus, and is an absolute indication for surgical treatment at the time of diagnosis. Transthoracic echocardiography is considered practically uninformative in the diagnosis of vascular rings due to the limitation of the ultrasound window. The final diagnosis of a double aortic arch is carried out using other radiation methods of research. Our experience with newborns shows that the features of imaging in this period can allow us to verify the discussed pathology and detail the anatomy of the defect in order to answer key clinical questions and complete the diagnostic search. The article describes a clinical case of verification of a double aortic arch using transthoracic echocardiography in a newborn on the 1st day of life, which demonstrates the possibilities of ultrasound imaging of a double aortic arch with two functioning arches in the early neonatal period.
