Variants of The Aortic Arch

Abstract The aortic arch is a crucial structure in the cardiovascular system, giving rise to several major arteries that supply blood to the head, neck, and upper limbs. Variations in the branching pattern of the aortic arch are relatively common and arise due to the abnormal development of the embryonic aortic arches. This study aims to identify and characterize the different branch variants of the aortic arch using contrast-enhanced computed tomography (CT) scans. Conducted as a retrospective study at MGM Hospital Navi Mumbai over a period of four months, the research involved a thorough review of CT scans performed on patients for various clinical indications. This research underscores the importance of imaging modalities, particularly contrast-enhanced CT scans, in the evaluation of aortic arch anatomy. The findings contribute to the existing body of knowledge on vascular anatomy and emphasize the need for careful pre-procedural planning to account for anatomical variations.
