Characteristics and Outcome of Abdominal Aortic Aneurysm in Emregncy Department; a 10-year Cross-sectional Study

Introduction: Abdominal aortic aneurysm (AAA, triple A) is one of the less common but important causes of abdominal pain. This study aimed to evaluate the characteristics and outcome of patients presenting to emergency department with triple A. Methods: In this retrospective cross-sectional study, all cases with confirmed triple A, who were presented to the emergency department of Shohadaye Tajrish Hospital, Tehran, Iran from 2006 to 2017 (10 years) were enrolled using census sampling method. Results: 500 cases with the mean age of 68.11 ± 11.98 (25 - 94) years were studied (84% male). The mean duration of symptoms was 2.32 ± 9.58 months and mean aneurysmal size was 63.91 ± 20.08 mm. In 4 (0.8 %) cases, atrial fibrillation (AF) was found during cardiac monitoring. Patients stayed in the hospital for an average of 7.06 ± 6.32 days. Aneurysmal leak was seen in 130 (26%) cases based on abdominal computed tomography (CT) scan findings. 369 (73.8%) cases underwent aneurysmorrhaphy, 126 (25.2%) were treated with non-surgical approaches, and 5 (1%) underwent grafting. 104 (20.8%) died and 396 (79.2%) were treated successfully. Older age (p = 0.017), shock state at the time of presentation (p < 0.0001), leakage of aneurysm (p < 0.001), larger size of aneurysm (p = 0.024), and aneurysmorrhaphy (p < 0.001) were among the factors significantly associated with mortality. Conclusion: Based on the findings, the most frequent presenting symptom of patients was abdominal pain. The mortality rate of this series was 21% and older age, shock state, leakage of aneurysm, larger size of aneurysm, and performing aneurysmorrhaphy were among the factors significantly associated with mortality.
