Outcomes After Elective Aortic Aneurysm Repair: A Nationwide Danish Cohort Study 2007–2010

Objective To assess outcomes after treatment for asymptomatic abdominal aortic aneurysm (AAA) in Denmark in a period when both open surgery (OR) and endoluminal repair (EVAR) have been routine procedures. Methods We performed a retrospective nationwide cohort study of patients treated for asymptomat...

Description
Summary:Objective To assess outcomes after treatment for asymptomatic abdominal aortic aneurysm (AAA) in Denmark in a period when both open surgery (OR) and endoluminal repair (EVAR) have been routine procedures. Methods We performed a retrospective nationwide cohort study of patients treated for asymptomatic AAA between 2007 and 2010. Data on demographics, procedural data, perioperative complications, length of stay (LOS), 30-day reinterventions and readmissions, late aneurysm and procedure-related complications and mortality were obtained from the Danish Vascular Registry and the Danish National Patient Register. Results 525 EVAR and 1176 OR for asymptomatic AAA were identified. LOS was shorter after EVAR than OR (4 vs. 7 days, p <  .001). During primary hospitalization procedure-related complications (12% vs. 6%) and general complications (21% vs. 8%) were more common after OR than EVAR ( p <  0.001). The 30-day reintervention rate was higher for OR than EVAR (18% vs. 6%, p <  0.001), but there was no difference in readmissions within 30 days. During follow-up (mean 29 ± 15 months) aneurysm-related complications after EVAR were outweighed by procedure-related complications after OR. Conclusion Elective AAA repair in Denmark is overall comparable with international results and both perioperative and late outcomes after EVAR of elective AAA are better than the results after OR.
