Film evaluation summary the reported endoleak could be confirmed on the still images provided; however, the cause or type of endoleaks could not be determined.Post-implant ct¿s were not available for review and the stent graft in-vivo configuration could not be evaluated.Endoleak interrogation via additional selective angiograms (injecting from different levels within the stent graft) to help determine the source would have been beneficial and only a single imaging view point was observed in the films provided; thereby, making determination of the endoleak difficult.Although a type ia endoleak seems most likely, it is also possible that a type ii or type iiib endoleak may have occurred and cannot be ruled out from the films provided.Analysis of the returned images did not reveal any obvious out of specification stent graft integrity issues.Additional information received; a non mdt stent graft was implanted ~22 months post index procedure to treat the ia endoleak.This resolved the endoleak and the patients pain resolved.Medtronic is submitting this report to comply with fda reporting regulations under 21 cfr parts 4 and 803.This report is based upon information obtained by medtronic, which the company may not have been able to fully investigate or verify prior to the date the report was required by the fda.Medtronic has made reasonable efforts to obtain more complete information and has provided as much relevant information as is available to the company as of the submission date of this report.This report does not constitute an admission or a conclusion by fda, medtronic, or its employees that the device, medtronic, or its employee caused or contributed to the event described in the report.In particular, this report does not constitute an admission by anyone that the product described in this report has any ¿defects¿ or has ¿malfunctioned¿.These words are included in the fda 3500a form and are fixed items for selection created by the fda to categorize the type of event solely for the purpose of regulatory reporting.Medtronic objects to the use of these words and others like them because of the lack of definition and the connotations implied by these terms.This statement should be included with any information or report disclosed to the public under the freedom of information act.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.A good faith effort will be made to obtain the applicable information relevant to the report.If information is provided in the future, a supplemental report will be issued.
