Case in brief
A patient with a rare congenital combination of aortic atresia and type B interrupted aortic arch had cerebral and coronary perfusion dependent solely on the left vertebral artery, with no alternative circulatory pathways in the thoracic cavity. The patient underwent successful single-stage biventricular repair and has shown favorable neurodevelopmental progress.
What made this case unusual
The left vertebral artery was the sole route supporting both cerebral and coronary perfusion, without an alternative thoracic circulatory pathway.
Diagnostic / clinical pearl
In aortic atresia with type B interrupted aortic arch, defining the vertebral artery’s role and the available collateral pathways is important for understanding cerebral and coronary perfusion.
