CTICasesAortic Coarctation Bypass Graft
Imaging findings
Chest radiograph and CT angiogram demonstrate an extra-anatomic ascending-to-descending aorta bypass graft coursing through the left hemithorax, surrounded by lung tissue. A stent is also visible in the proximal descending aorta.
Key takeaways
Ascending-to-descending aortic bypass is an extra-anatomic surgical technique used to treat complex or recurrent aortic coarctation. The graft courses through the posterior mediastinum/left hemithorax and can mimic a mediastinal or pleural mass on radiographs.
