CTICasesCoarctation Bypass Graft Calcification
Imaging findings
Chest radiograph and CT show a calcified tubular structure in the posterior mediastinum, representing a bypass graft running from the ascending aorta to the descending thoracic aorta. The patient has a childhood history of coarctation surgery.
Key takeaways
Surgical bypass from the ascending to the descending aorta is a classic repair option for complex or recurrent aortic coarctation. Over decades, these prosthetic bypass grafts can develop extensive mural calcification, which is easily visible on radiographs.
