Infolding of a fenestrated-branched stent graft is an infrequent complication due to excessive oversizing. We report the case of an 89-year-old man who underwent a four-vessel fenestrated-branched endovascular aortic repair for a pararenal aortic aneurysm. Computed tomography angiography revealed severe infolding across the mesenteric-renal vessels. The patient was treated by angioplasty and placement of Palmaz stent. Cone-beam computed tomography confirmed patent visceral vessels with resolution of the infolding. This case illustrates an uncommon complication that can be prevented by modifications in the stent design and by immediate assessment using intraoperative cone-beam computed tomography.
开窗分支型覆膜支架的折叠是由于尺寸过大导致的一种罕见并发症。我们报告了一例89岁男性患者，其因肾旁主动脉瘤接受了四支血管开窗分支型血管腔内主动脉修复术。计算机断层扫描血管造影显示肠系膜 - 肾血管严重折叠。患者接受了血管成形术并植入了帕尔马兹支架。锥形束计算机断层扫描证实内脏血管通畅，折叠消失。该病例说明了一种罕见的并发症，可通过改进支架设计和术中使用锥形束计算机断层扫描进行即时评估来预防。
