The Impact Associated with Changing Practice Patterns for the Treatment of Abdominal Aortic Aneurysms in the United States

We have witnessed an evolution in the treatment of abdominal aortic aneurysm (AAA) from open to endovascular repair. The implications that these changes had on outcomes, not been thoroughly studied. evaluated trends volume and AAA repairs done nationwide a recent 20-year period, outcomes associated with each type repair, assess how may changed over this period. Patients undergoing elective repair between 2000 2020 were identified using TriNetX Analytics Network, federated network healthcare organizations provides deidentified patient data. first-time or (infrarenal visceral) 2001 separated, plotted time, propensity score matched. Primary outcome was mortality; secondary included myocardial infarction (MI), pneumonia acute kidney injury (AKI). Over period we 21,368 patients 6473 patients. surpassed 2004 2005 saw steady increase (Fig 1). From 2010, mortality 2.35% for 0.98% (P < .001); MI 1.40% 0.90% = .0004); 2.77% 1.03% AKI 1.85% 0.91% .0014). 2011 5.07% 3.89% .09); 2.48% 2.39% .375); 4.21% 3.10% .02); 6.53% 4.65% .07).
