The aim of this study is The current guidelines recommend elective abdominal aortic aneurysm (AAA) repair at 5.5 cm in men and 5.0 cm in women. However, rupture occurs in patients with aneurysm size below these thresholds. This study aimed to investigate the proportion of small ruptured AAAs (rAAAs) below elective operative thresholds and to compare outcomes of repair with larger aneurysms.
The 2011 to 2018 American College of Surgeons National Surgical Quality Improvement Program open and endovascular AAA repair databases were reviewed for all cases of rAAA. This study clearly depicts that out Of the 1612 ruptured AAA repairs, 167 (10.4%) were small rAAAs. Patients in the small AAA group were more likely to be assigned to American Society of Anesthesiologists class ≤3 and to undergo endovascular aneurysm repair but less likely to have hypotension on presentation. Repair of small rAAA was associated with lower bleeding, mortality, and mean operative time and higher readmission. Multivariate analysis showed that rupture with hypotension, open repair, general anesthesia, age, and high American Society of Anesthesiologists class were associated with increased mortality, but aneurysm size was not.
