CTICasesAortic Graft Infection post Type-A Dissection Repair
Imaging findings
CT angiography shows a progressive increase in fluid and inflammatory stranding surrounding a repaired ascending aortic graft and d-branched arch. Blood cultures were positive, despite a negative transesophageal echocardiogram (TEE) and negative white blood cell scan.
Key takeaways
Prosthetic aortic graft infection is a life-threatening complication that can present insidiously with bacteremia. CT findings include increasing perigraft fluid, gas, or soft tissue stranding. Nuclear medicine tests (like white blood cell scans) can sometimes be false-negative due to prior antibiotic therapy or cell degradation, making CT findings key.
