CTICasesAortobronchial Fistula due to Pseudoaneurysm Post Coarctation Repair

Imaging findings
Twenty years after open surgical coarctation repair, a patient experienced massive hemoptysis. Imaging showed an area of narrowing at the prior anastomosis site with a pseudoaneurysm extending into the adjacent lung parenchyma, leading to intrapulmonary hemorrhage. This was surgically and clinically confirmed as an aortobronchial fistula.
Key takeaways
Aortobronchial fistula is a known, albeit rare, late complication following coarctation repair, often caused by pseudoaneurysm formation at the anastomotic site. This condition can present with life-threatening hemoptysis and requires prompt diagnosis and surgical intervention.
