Right Aortic Arch with Aplasia of the Left Brachiocephalic Trunk Presented as Systolic Blood Pressure Difference Between Upper Extremities

摘要

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.
