A case of right ductus and left innominate artery from the pulmonary trunk

Abstract

Right-sided aortic arch is a rare anatomic variation of aortic arch anomaly, which may coexist with or without other cardiac defects. We report an extremely rare case of right-sided aortic arch with a right ductus arteriosus and isolation of the left brachiocephalic trunk, without other associated intracardiac lesions. We describe the successful surgical management of this anomaly in a neonate who had bilateral choanal atresia without DiGeorge syndrome or Down syndrome. However, our patient had clinical signs of hearing loss in the postoperative follow-up period.

Case Report: Right aortic arch with isolation of left brachiocephalic artery and ventricular septal defect

“…Therefore, we suggested that the continuity between the LBA and the aorta should be reconstructed for this anomaly, which is very important to preserve normal perfusion of the cerebral and left upper extremity and maintain organs development. Various surgical techniques for reconstructed the continuity between the LBA and the aorta had been reported in previous literature, such as direct anastomosis of IBA and aorta ( 4 , 5 , 10 ), using a synthetic tube to connect the LBA and the aorta ( 6 ). In our patient, there was a significant distance between the isolated LBA and the aortic arch, two vessles were unable to be anastomosed directly.…”

Morphometry of the Brachiocephalic Artery: A Cadaveric Anatomical Study

“…Several variations have been reported regarding the point from which the BCA arises, the pulmonary trunk being an extremely rare case [ 3 ]. The existence of two BCAs is also reported [ 4 ] and even the total absence of it.…”
