    Description of Event or Problem · 1

    MEDTRONIC RECEIVED THE FOLLOWING INFORMATION OBTAINED FROM THE JOURNAL ARTICLE ENTITLED; LONG-TERM SINGLE-CENTER RESULTS WITH ANEURX ENDOGRAFTS FOR ENDOVASCULAR ABDOMINAL AORTIC ANEURYSM REPAIR. JOOST A. VAN HERWAARDEN, MD, PHD^ "; ERIC D.W.M. VAN DE PAVOORDT, MD, EVERT J. WAASDORP, MD^; JAN ALBERT VOS, MD^; TIM THC. OVERTOOM, MD2; JOHANNES C. KELDER, MD3; FRANS L MOLL, MD, PHD"; AND JEAN-PAUL P.M. DE VRIES, MD, THE NETHERLANDS. AN ANEURX STENT GRAFT SYSTEM WAS IMPLANTED IN THE PATIENT FOR THE ENDOVASCULAR TREATMENT OF ENDOVASCULAR REPAIR. DURING THE RETROSPECTIVE STUDY THE FOLLOWING ADVERSE EVENTS WERE OBSERVED: RUPTURE, CONVERSION PURPOSE: TO EVALUATE THE LONG-TERM SINGLE-CENTER RESULTS WITH THE ANEURX STENT-GRAFT IN ENDOVASCULAR ABDOMINAL AORTIC ANEURYSM (AAA) REPAIR (EVAR). METHODS: BETWEEN DECEMBER 1996 AND AUGUST 2003, 212 PATIENTS (197 MEN; MEAN AGE 71.3±7.0 YEARS) WERE TREATED WITH THE ANEURX STENT-GRAFT FOR AN INFRARENAL AAA. POSTOPERATIVELY, PATIENTS WERE ENROLLED IN A FIXED SURVEILLANCE PROTOCOL, AND DATA WERE PROSPECTIVELY CAPTURED INTO A DATABASE. RESULTS: GRAFT DEPLOYMENT WAS SUCCESSFUL IN 98.6% (209/212). THIRTY-DAY MORTALITY WAS 2.4%. MEDIAN HOSPITAL STAY WAS 4.3±5.5 DAYS. MEDIAN FOLLOW-UP WAS 52.0 MONTHS (RANGE 1-109); ONLY 1 PATIENT WAS LOST TO FOLLOW-UP. AT 9 YEARS, PATIENT SURVIVAL WAS 56% AND FREEDOM FROM SECONDARY INTERVENTIONS WAS 48%. IN 68% OF CASES, THESE REINTERVENTIONS WERE NEEDED FOR A FIXATION-RELATED COMPLICATION, AND MOST OF THESE COMPLICATIONS (75%) ENCOMPASSED THE AREA OF THE PROXIMAL ANEURYSM NECK. PRIMARY CLINICAL SUCCESS WAS 37% AT 9 YEARS. AFTER SECONDARY INTERVENTIONS, THE ASSISTED PRIMARY CLINICAL SUCCESS IMPROVED TO 73% AT 9 YEARS. FREEDOM FROM ANEURYSM-RELATED DEATH WAS 97% AT 1 YEAR AND 90% AT 9 YEARS. CONCLUSION: AS AN ALTERNATIVE TO OPEN REPAIR, EVAR WITH THE ANEURX DEVICE HAS LOW PERIOPERATIVE MORTALITY. REINTERVENTIONS ARE MOSTLY DUE TO FIXATION-RELATED COMPLICATIONS. WHILE THE OVERALL MORTALITY RISK IN THIS POPULATION WAS 5% PER YEAR, ANNUAL ANEURYSM RELATED DEATH WAS ONLY 1%. THE FOCUS SHOULD BE ON SURVEILLANCE AND REDUCING THE RATE OF LONG-TERM COMPLICATIONS, WHICH MIGHT BE POSSIBLE WITH IMPROVED PROXIMAL STENT-GRAFT FIXATION.
