Comparing Trends Between 2004 and 2019 in Intact and Ruptured Abdominal, Thoracic, and Thoracoabdominal Aortic Aneurysms Spanning ICD9 and ICD10 Within the NIS Database

Given the changes in intervention guidelines and growing popularity of endovascular treatment for aortic aneurysms since turn millennium, we used Nationwide Inpatient Sample to examine trends abdominal aneurysm (AAA), thoracoabdominal (TAAA), thoracic (TAA) rupture presentations intact repairs along with methods (endovascular vs open). Analyses spanning change coding from International Classification Diseases, 9th or 10th edition, has yet be studied. We identified all patients presenting ruptured intervened on between 2004 2019. This included AAA, TAAA, TAA. then examined utilization open repair each location (AAA, TAA), alongside their resulting in-hospital mortality, over time. Cochran-Armitage z statistic tests a linear trend generate P values frequencies hospitalizations, interventions, other patient characteristics as well regression various outcome variables. Overall, 717,570 AAA (87% repair, 13% ruptured), 27,443 TAAA (80% 20% 141,652 TAA (90% 10% ruptured). Both hospitalizations decreased significantly 2019 (both < 0.001). Intact increased (trend 0.001), while 15-year period Finally, same had no significant = .381). Proportionally time use EVAR c-EVAR (all .001) (Fig 1). Analyzing 2019, mortality after significantly, 2.74% 1.18% (−0.11%/year [95% confidence interval (CI), −0.12% −0.08%]; .001), 12.20% 9.76% (−0.25%/year CI, −0.44% −0.05%]; .013), 3.54% 2.35% (−0.07%/year −0.03%]; 2). Conversely, increased. These increases elective are most likely driven by increasing new complex allowing otherwise unfit surgical repair.Fig 2Trend respective regressions.View Large Image Figure ViewerDownload Hi-res image Download (PPT)
