A 63-year-old patient with chronic thoracoabdominal aortic dissection was found to have a 2.2 cm wide-neck splenic artery aneurysm. The interdisciplinary treatment plan required exclusion of the splenic artery aneurysm before fenestrated endovascular aortic repair. During the first intervention, deployment of a Viabahn endoprosthesis was technically difficult. The device kinked and displaced distally, leaving the aneurysm perfused. Because the intervention had already lasted more than 3 hours and required approximately 150 mL of non-ionic contrast medium, the procedure was stopped. The patient was monitored first in the recovery room and then on a regular ward. A longer Viabahn device was ordered and delivered at short notice. Two days later, balloon-assisted realignment of the displaced stent graft and overlapping placement of the second device achieved complete aneurysm exclusion while preserving splenic perfusion. The patient was discharged home the following day. One-year CT angiography confirmed persistent exclusion of the aneurysm and patency of the treated splenic artery. This case illustrates practical bailout techniques for an uncommon but demanding deployment complication.
