Description
Introduction: Blunt abdominal trauma affects 25% of all patients admitted with traumatic injuries. Although relatively rare, the development of solid organ pseudoaneurysms (PSA) can pose a significant threat to patients. If untreated, these PSAs may rupture and lead to life- threatening hemorrhage. Despite this risk, the use of follow-up imaging after initial CT for abdominal trauma has not been widely embraced.
Methods: A database was created to include all adult patients admitted at a level 1 and a level 2 trauma center between 2012 and 2020 for abdominal injuries with an AAST grade of ≥3. A retrospective review of this database was conducted to identify patients with PSAs and their outcomes.
Results: A total of 1,260 patients were identified with high-grade abdominal injuries. Forty- seven of these patients had a PSA. The median AAST grade was 4. Seventy percent had extravasation on initial CT imaging, and 76.6% underwent IR embolization. Only 12 patients (25.53%) had CT angiography prior to discharge, and 6.38% required readmission for treatment of their PSA. Allcause mortality in these patients was 14.89%.
Conclusion: The incidence of PSAs in this series is consistent with that seen in previous literature; however, previous literature has excluded patients with penetrating trauma. Given this population's high percentage of penetrating trauma, this research highlights a potential new focus. Both participating hospitals have used our findings to inform new guidelines. Now all patients with solid organ injuries with an AAST grade of 3 or higher are required to undergo CTA surveillance prior to discharge to screen for PSA.
