Multicenter Study Comparative Study
Outcomes of symptomatic abdominal aortic aneurysm repair.
Operative mortality of patients undergoing symptomatic abdominal aortic aneurysm (Sx-AAA) repair has been reported at 6% to 30% during the past 25 years. We used a multicenter regional database to describe the contemporary outcomes of patients undergoing repair of Sx-AAA. ⋯ The operative mortality of patients with Sx-AAA in contemporary practice appears better than that previously reported in the literature. Despite low operative mortality, MAE and late survival are intermediate compared with E-AAA and R-AAA repair. Review of previous series shows a trend for lower operative mortality after Sx-AAA repair in more recent series, which likely reflects improved perioperative care and more use of endovascular aneurysm repair.

Multicenter Study
Existing risk prediction methods for elective abdominal aortic aneurysm repair do not predict short-term outcome following endovascular repair.
Improving the safety of elective abdominal aortic aneurysm (AAA) repair has become an imperative. Five well-described risk-scoring systems developed on open aneurysm repair (OR) were tested on a multicenter contemporary sample of patients undergoing endovascular repair of AAA (EVR) to determine if they predicted 30-day morbidity and mortality. ⋯ None of the available scores predicted the outcome of EVR with enough accuracy to be recommended for clinical use. To improve preoperative risk prediction in EVR validation of new systems is required, taking into account morphologic features of the aneurysm to predict medium-term morbidity and re-intervention.
