To report a case of aortoenteric fistula secondary to endovascular abdominal aortic aneurysm (AAA) exclusion using the Stentor bifurcated endovascular graft.
Seventeen months after a successful endovascular AAA procedure, a male patient developed upper gastrointestinal bleeding. An aortoenteric fistula was diagnosed. At operation, the endograft fabric was found to be ruptured in an area of suture disruption between the nitinol stents. Coincidentally, a pre-existing inflammatory process might have caused adhesions between the bowel and the aortic wall, predisposing to fistula formation. The patient recovered after placement of a conventional aortic graft.
Suture disruption between the internal support stents is a recognized complication in the first-generation Stentor device. Although the case described here is probably not typical of the consequences of this sequela, it does reinforce the need for continual periodic imaging to check for signs of graft disruption in Stentor endografts.
报告一例使用Stentor分叉型血管内移植物进行血管腔内腹主动脉瘤（AAA）隔绝术后继发主动脉肠瘘的病例。
在成功进行血管腔内AAA手术17个月后，一名男性患者出现上消化道出血。诊断为主动脉肠瘘。手术中发现，在镍钛诺支架之间的缝线断裂区域，血管内移植物织物破裂。巧合的是，先前存在的炎症过程可能导致肠管与主动脉壁之间形成粘连，易引发瘘管形成。患者在植入传统主动脉移植物后康复。
第一代Stentor装置中，内部支撑支架之间的缝线断裂是一种公认的并发症。尽管此处描述的病例可能并非这种后遗症后果的典型情况，但它确实强化了持续定期成像以检查Stentor血管内移植物有无移植物破裂迹象的必要性。
