Imaging findings
The imaging showed a right-sided aortic arch that crossed the midline to descend on the left side, confirming a circumflex aortic arch. The patient also had a sub-aortic left brachiocephalic vein, another vascular anomaly often seen in this context.
Key takeaways
A circumflex aortic arch is a variant where the arch crosses the mediastinum to the contralateral side. Recognizing this vascular anatomy is important, as it can be associated with other congenital cardiovascular anomalies.
