ABSTRACT

Objective:

To explore the prenatal ultrasound manifestations of fetal congenital right aortic arch and its diagnostic significance.

Methods:

The characteristics of prenatal ultrasound images (focusing on the three vessel trachea section) and clinical data of 128 cases of fetal congenital right aortic arch diagnosed in Dalian Women and Children′s Medical Center(Group) from January 2014 to January 2019 were analyzed retrospectively.

Results:

Among 128 cases of fetal congenital right aortic arch, 111 cases were right aortic arch and leftductus arteriosus with aberrant left subclavian artery (RAA-LDA-ALSA), 1 case was diagnosed as left aortic arch atresia of double aortic arch by operation after birth; 9 cases were right aortic arch and right ductus arteriosus (RAA-RDA); 6 cases were mirror-image right active aortic arch and left ductus arteriosus connected to descending aorta (RAA-BAMB-LDA-DAO); 2 cases were mirror-image right aortic arch and left ductus arteriosus connected to the left innominate artery (RAA-BAMB-LDA-LINA). The three vessels and trachea view (3VT) had characteristic sonographic features.If necessary, coronary section of the upper thoracic aorta and / or stic were added - HD live flow technology assisted the diagnosis of 3vt section.

Conclusions:

Three vessel trachea view is a sensitive and effective view for prenatal detection and diagnosis of congenital right aortic arch. Upper thoracic aorta coronal section and combined stic - HD live flow technology can make up for its shortcomings. Prenatal ultrasound diagnosis of right aortic arch hasguiding significance for prenatal prognosis consultation.
