OBJECTIVE: The Zenith Renu @entity1028 ( @entity1028 ) Ancillary Graft (Cook Medical Inc, Bloomington, Ind) provides active proximal fixation for treatment of pre-existing endografts with failed or failing proximal fixation or seal. The purpose of this study was to evaluate the midterm outcomes of treatment with this device. METHODS: From September 2005 to November 2006, a prospective, nonrandomized, multicenter, postmarket registry was utilized to collect physician experiences from 151 cases (89 converters and 62 main body extensions) at 95 institutions. Preoperative indications and procedural and postimplantation outcomes were collected and analyzed. Technical success and clinical success were determined as defined by the Society of Vascular Surgery reporting standards. RESULTS: @entity1 were predominantly male (87%) with a mean age of 77 years. The interval between the original endograft implantation to Renu treatment was 43.4    18.7 months. The indications for treatment were @entity1070 (n = 111), migration (n = 136), or both (n = 94). Technical success was 98.0% with two cases of intraoperative conversion and one case of persistent @entity1070 . The median follow-up for the cohort was 45.0 months (range, 0-56 months; interquartile range, 25.0 months). Overall, 32 cases had treatment failures that included at least one of the following: @entity204 (n = 5), @entity1070 (n = 18), graft infection (n = 1), @entity715 (n = 1), @entity439 >5 mm (n = 9), @entity397 (n = 4), conversion (n = 9, with 7 after 30 days), and migration (n = 1). Overall, the clinical success for the entire cohort during the follow-up period was 78.8% (119/151). CONCLUSIONS: The postmarket registry data confirm that the Zenith Renu @entity1028 Ancillary Graft can be used to treat endovascular repairs that failed due to @entity177 . The salvage treatment with the Renu device had high technical success rate and resulted in clinical success in a majority of @entity1 (78.8%). While failed endovascular repairs can be salvaged, a clinical failure in one of five @entity1 still emphasizes the importance of @entity1 and device selection during initial @entity439 repair to ensure durable success.
