Concomitant medical products: zalb-30-108 lot: 6137166; zsle-16-74 lot: 6883852; zsle-16-90 lot: 5821557.Patient code: no code available - surgical intervention required.Investigation/evaluation: the device was not available for evaluation.Without the complaint device, a physical investigation was not able to be completed.Imaging was provided for review.A document based investigation has been performed including a review of the provided imaging, device history record, instructions for use, and quality control data.Each zenith device is shipped with instructions for use (ifu), which states warnings, precautions and instructions for use.Warnings and precautions state that patients with poor outflow or a hypercoagulable state (e.G., cancer) may be at an increased risk of a thromboembolic event.The device history record was reviewed and no non-conformances related to the reported failure mode were noted.Impressions of the imaging reviewer: right zsle thrombosis with occlusion is confirmed.The extent and thickness of mainbody thrombus was greater than usual and may have been encouraged by thrombus filling the distal mainbody dead space.The dead space thrombus could not have been the primary cause.Otherwise, the left zsle which was much closer and surrounded by the dead space thrombus would have thrombosed instead.The right zsle thrombosis was without anatomic explanation.The zsle was widely patent, straight, and without inflow or outflow obstruction.A right renal infarct was present.A two-year post implantation computed tomography angiography (cta) was provided and reviewed.Right zsle thrombosis with occlusion is confirmed.There was dead space in the distal main body lumen created by bilateral zsle extension into the endograft lumen.Thrombus also lined the mainbody and the filled dead space.The mainbody mural thrombus was continuous with the right zsle thrombus.The inferior pole, right kidney was infarcted from sealing stent covering of an inferior accessory right renal origin.Based on the information provided and the image review a cause for thrombus in the right zsle could not be established.A quality engineer risk assessment was conducted to assess the risk of this failure mode and concluded a change is not required, thus no risk reduction activities are required at this time.The appropriate internal personnel have been notified and we will continue to monitor for similar complaints.This report is required by the fda under 21 cfr part 803 and is based on unconfirmed information submitted by others.Neither the submission of this report nor any statement contained herein is intended to be an admission that any cook device is defective or malfunctioned, that a death or serious injury occurred, nor that any cook device caused, contributed to, or is likely to cause or contribute to a death or serious injury if a malfunction occurred.
