(b)(4).This event is currently under investigation.
Event or Problem Description
An (b)(6) year old male patient underwent aaa repair.The patient's anatomical form was suitable for endovascular repair.The ima was coil embolized prior to placing the stent grafts.After placing body and two iliac leg grafts, the user did ballooning with coda-2-10.0-35-120-32 as labeled.Final angiogram was performed and the physician confirmed jet-like contrast from around the fourth strat of the main body; (1820334-2017-00366).He then performed angiogram inside the main body and confirmed the same contrast and suspected it was type iii endoleak from suture hole.To avoid enlarging the suture hole, he decided not to perform additional ballooning at the leak site and to take wait-and-see approach and completed the procedure.Additional information provided on (b)(6) 2017 stated the physician commented that a slight amount of 'leak-like' thing was confirmed at a follow-up exam.However; no health hazard has been occurred.Additional information provided by the imaging review conducted on (b)(6) 2017 (related reference # 1820334-2017-00366) indicated that there are also type 3b endoleaks on the right leg (this report 1820334-2017-00632) and on the left leg (ref # 1820334-2017-00633).
Additional Manufacturer Narrative
Investigation - evaluation.A review of the complaint history, device history record, instructions for use (ifu), quality control, and inspection of imaging was conducted during the investigation.The complaint device was not returned therefore, no physical examinations could be performed; however, a document based investigation evaluation was performed.There is no evidence to suggest the finished product was not made to specifications.Review of the device history record of the finished product shows no nonconforming events that would contribute to this failure mode.There were no other reported complaints for this lot number.The report from the imaging review states the endoleak to be multiple type iiib endoleaks through suture holes, likely due to aggressive anticoagulation and limited outflow of blood due to very slow to static left external iliac artery (eia) flow and the presence of the introducer sheath.In addition, the eia¿s were small, necessitating aggressive anticoagulation to prevent thrombus formation around the left eia sheath.The limited outflow of blood was likely due to small external iliac arteries and the presence of the sheath in the arterial vasculature during angiography.This would have increased the likelihood of provoking the suture holes due to increasing graft pressure.Multiple endoleaks are also associated with aggressive anticoagulant use, which often occurs during endovascular aneurysm repair (evar) procedures.Based on the information in the complaint report and the image review, the root cause of the type iiib / suture hole endoleaks is procedure-related / patient condition-related.
