CTICasesRight Aortic Arch with Circumflex Arch/Vascular Ring
Imaging findings
Chest imaging showed a right-sided aortic arch where the entire arch courses posterior to the esophagus before descending on the right side, creating a vascular ring. Surgical clips from a previous ligation of the ligamentum arteriosus were present. The trachea exhibited deviation and uniform intrathoracic narrowing.
Key takeaways
This case illustrates a right aortic arch with a circumflex configuration forming a vascular ring. While previous surgical intervention (ligamentum arteriosus ligation) was performed, the case highlights the persistent symptoms that may necessitate more complex "uncrossing" procedures.
