Right aortic arch with aplasia of the left brachiocephalic trunk presented as systolic blood pressure difference between upper extremities

BACKGROUND: The right aortic arch with mirror-image of branching arteries without coexisting congenital heart disease is a very rare anomaly. CASE REPORT: We report a case of the right-sided aortic arch with aplasia of the left brachiocephalic trunk in a 64-year-old women, presenting difference in systolic blood pressure between upper extremities. The history of the patient and angio-CT findings were described and visualized with images. CONCLUSIONS: The knowledge of vascular variations is important for the clinical and therapeutic aspects.
