Treatment of primary infected juxtarenal aortic aneurysm with the multilayer stent.

PURPOSE

To report the use of multilayer uncovered stent to treat primary infected juxtarenal aortic aneurysm.

CASE REPORT

A 50-year-old man was admitted to hospital for rapid onset of intractable abdominal pain and high fever. Computed tomographic scan showed 2 juxtarenal saccular aneurysms of abdominal aorta with morphologic and clinical changes compatible with infectious etiology. Patient was treated with multilayer flow-modulating stent. Follow-up imaging showed persistent aneurysm exclusion and continuous aneurysm shrinkage of the sac until complete regression to a normal aortic configuration was seen at 1 year. During follow-up (24 months), patient continued to do well, and there was no recurrence of infection.

CONCLUSION

Multilayer stent appeared to be an acceptable treatment option for primary infected juxtarenal aortic aneurysms. Aneurysmal sac completely disappeared and visceral branches remained patent at 2-year follow-up. However, longer follow-up is necessary to evaluate the long-term patency of involved visceral arteries.
