Abstract
Right-sided aortic arch (RAA) is a rare anatomical variant, often discovered
incidentally during imaging studies. We present a comprehensive case study
of a 77-year-old male with an asymptomatic RAA, emphasizing the crucial
role of multimodal imaging in accurate diagnosis. This report explores the
imaging findings, potential clinical implications, and the significance of
identifying such anomalies for patient management.
Right-sided aortic arch (RAA) is an uncommon congenital anomaly
characterized by the aorta's deviation to the right of the trachea. While
often asymptomatic, its recognition is vital for understanding associated
vascular anomalies and potential clinical implications. This case study delves
into the imaging nuances, embryological basis, and clinical considerations
associated with RAA with mirror image branching of the arch vessels,
contributing valuable insights to the existing medical literature.
Multidetector computed tomography (MDCT) revealed a right-sided aortic
arch with mirror-image branching of the arch vessels. The arch descended
on the right side of the trachea, forming a vascular ring.The anomalous
arrangement of the left common carotid artery originating from a left
brachiocephalic trunk together with the left subclavian artery.Diagnosis:
Right-sided aortic arch with mirror-image branching.
The embryological basis of RAA involves intricate processes leading to
abnormal arch regression and persistence of the right dorsal aorta. The
clinical significance lies in potential complications, including tracheal
compression and vascular ring formation. Accurate diagnosis through
advanced imaging allows for informed decision-making and appropriate
patient management. Right-sided aortic arch is a rare anatomical variant
that warrants attention due to its potential clinical implications. Awareness
of such anomalies and their associated vascular configurations is essential
for providing optimal patient care. This case contributes to the limited
literature on RAA, emphasizing the importance of thorough imaging in
unraveling complex vascular variations.
Key words: Right-sided aortic arch,multidetector computed
tomography,diagnosis.
