Three cases of recurrences after stent-graft placement for arterio-visceral/arterio-luminal fistulas in long-term follow-up.

We report 3 patients with recurrences after stent-graft placement for arterio-visceral/arterio-luminal fistulas in long-term follow-up. Two patients had ureteroarterial fistulas and the other had a tracheo-innominate artery fistula. All 3 patients had hemorrhage on initial presentation and underwent a stent-graft placement for an arterio-visceral/arterio-luminal fistula. Recurrences occurred over a period of 8-26 months and were diagnosed by contrast-enhanced computed tomography; pseudoaneurysms were found in contrast-enhanced computed tomography images in all cases. Pseudoaneurysms may be noted on contrast-enhanced computed tomography as the only finding of recurrences during long-term follow-up after stent-graft placement for arterio-visceral/arterio-luminal fistulas.
