Conclusion
This case report shows a rare complication following failed endovascular
treatment, where growth of the saccular aneurysm in the presence of
ongoing infection and type Ib endoleak resulted in severe compression of
the trachea. Even though treatment of mycotic aneurysms improved due to
antibiotic treatment and endovascular stent grafting, complications and
graft failure do occur and can be lethal as presented in our case.
