Late infection of thoracic aortic stent graft with aerodigestive fistula: a case series and narrative literature review

1

Late thoracic aortic stent graft infection (ASGI) can lead to severe complications, including aerodigestive fistulas.
2

The study analyzed three cases of late ASGI, highlighting diverse presentations and surgical interventions.
3

The 30-day postoperative mortality rate for the cases was 33.3%, with a 1-year mortality rate of 100%.
4

Early recognition and source control are critical, yet managing late ASGI remains clinically challenging.
5

The incidence of ASGI is low, but it carries a high mortality rate, emphasizing the need for improved diagnostic strategies.
