Event Description

According to the publication, "prospective analysis of hemodialysis reliable outflow vascular access graft vs.Cuffed catheter access in hemodialysis," the prospective cohort study assessed clinical outcomes in 16 hero graft patients against a control group without hero (n=17) over one year.The adverse events associated with each patient are being reported collectively per patient as a determination could not be made regarding the relation of the associated events.Furthermore, the specific patient comorbidities and contributory factors for the reported adverse events cannot be correlated.The most common etiology of end-stage renal disease (esrd) was diabetes, hypertension, or the combination of both.The most common comorbidities in both study groups were diabetes mellitus, hypertension, and myocardial infarction.This medwatch is being submitted as product code hero 1001, however the scope of the investigation will evaluate both hero 1001 and hero 1002 components.This report is being submitted for patient 033.Patient 033 was a female who received a hero implant on (b)(6) 2012 and experienced the following adverse events: hospitalized on (b)(6) 2012 for "(b)(6) infection of perm cath" that was deemed "access related," treated on (b)(6) 2012 with thrombectomy/angioplasty for occlusion, treated on (b)(6) 2012 for pseudoaneurysm, hospitalized on (b)(6) 2012 for "graft infection (b)(6)" deemed "access related," (b)(6) 2012 for "sirs av graft infection," and hospitalized on (b)(6) 2015 for "(b)(6) sm+cocci." the hero graft was explanted on (b)(6) 2013 due to "abscess at graft site.".
