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.
我们报告了3例在长期随访中因动静脉/动腔内瘘放置支架移植物后复发的患者。2例患者患有输尿管动脉瘘，另1例患有气管无名动脉瘘。所有3例患者初次就诊时均有出血，并因动静脉/动腔内瘘接受了支架移植物置入术。复发发生在8 - 26个月期间，通过增强计算机断层扫描诊断；所有病例在增强计算机断层扫描图像中均发现假性动脉瘤。在因动静脉/动腔内瘘放置支架移植物后的长期随访中，假性动脉瘤可能是增强计算机断层扫描中复发的唯一表现。
