A valiant stent graft system was planned for implantation in a patient for the endovascular treatment of an unknown size thoracic aortic aneurysm.It was reported that during the index procedure, the physician attempted to insert the device but once at the aortic arch it would not pass over the arch, even after several attempts.During this process the iliac vein tore and the device was removed to get control of the iliac vein.He then attempted to pass the device again but it would still not pass.Another longer stent graft was then used which was successfully deployed and implanted to complete the procedure.As per the physician, the cause of the event was anatomy related.No additional clinical sequelae were reported and the patient is fine.
