Based on the information received at the completion of the clinical evaluation, there were not enough evidence to support the following case event.It was confirmed that patient had bilateral leg pain due to a collapsed, occluded proximal graft (ir cuff and mainbody).The report of cold legs were refuted, rather patient had a bilateral buttock claudication instead.Physician elected to do a surgical conversion (open repair), and device was discarded at the hospital.Cumulative knowledge informed by past assessments of similar complaints was applied to a review of the available medical information.The occlusion of the graft was most likely due to the proximal cuff collapse.The most likely cause of the buckled proximal cuff (collapse) could not be determined due to a lack of relevant imaging.Associated clinical harms for this event included: pain, ischemia, occlusion, surgical conversion, and abnormal blood loss.Additionally, the patient was readmitted twice during the thirty days following the conversion for low hemoglobin counts, and was treated medically (procedure related).The final patient disposition was discharged home with home health care and to be in good condition with no additional adverse events reported.A review of manufacturing lot confirmed all devices met specifications prior to release.These types of events will be monitored and trended as part of the quality system.
