Multicenter Study Comparative Study Clinical Trial
Outcome of endovascular abdominal aortic aneurysm repair in patients with conditions considered unfit for an open procedure: a report on the EUROSTAR experience.
Endovascular abdominal aortic aneurysm repair (EAR) can be performed in patients whose conditions were previously considered unfit for conventional treatment of the aneurysm. However, because the life span in this category of patients often is limited because of serious comorbidity, the efficacy of EAR in prolonging life expectancy remains uncertain. This study involves the evaluation of preoperative risk classification and an assessment of the outcome of interventions. ⋯ Early and late mortality rates were increased in patients with the preoperative clinical diagnosis "unfit for open surgery and general anesthesia" as compared with patients at "normal" operative risk. EAR appeared of potential benefit in patients with unfit conditions, regardless of the aneurysm diameter. The life expectancy of patients at high risk who are considered for EAR should be longer than 1 year before any realistic gain in life span can be anticipated.
