    Abstract:
    OBJECTIVE: The purpose of this study was to assess whether there is a difference in outcome of endovascular repair in patients with and without intraoperative adjuvant procedures. METHODS: Demographic, anatomic and operative details were assessed in patients undergoing endovascular repair using the EUROSTAR registry and correlated with morbidity and mortality rates. Three groups of adjuvant procedures: (A) endovascular, (B) surgical peripheral arterial and (C) surgical abdominal arterial were compared with a group of patients without an adjuvant procedure (D). Logistic regression and Cox proportional hazards model were used for statistical analysis. RESULTS: Of 4631 endovascular repairs, 1353 patients (29.2%) required adjuvant procedures. Additional endovascular procedures were performed in 1057 (78.1%), surgical peripheral arterial in 193 (14.3%) and surgical abdominal arterial in 103 (7.6%). The 30-day mortality rate was significantly higher in categories with peripheral arterial surgical (6.7%) and abdominal surgical procedures (7.8%) compared to patients without adjuvant procedures (1.5%, p = .001 and p = .004, respectively). Life-table-analysis demonstrated that late mortality, conversion or rupture rates were not increased in patients with an adjuvant procedure. CONCLUSION: Adjuvant surgical procedures were associated with increased 30-day mortality. Because of this higher risk, endovascular repair should be recommended with caution when surgical adjuvant procedures are anticipated.
