Delayed presentation of splenic artery pseudoaneurysms following blunt abdominal trauma: case reports.

Splenic artery pseudoaneurysms are known to be caused by either pancreatitis or operative trauma. We present two patients who had delayed presentation of splenic artery pseudoaneurysms secondary to blunt abdominal trauma. This is the first report of splenic artery pseudoaneurysms following trauma and demonstrates the importance of follow-up computed tomography scans in patients with splenic injuries who are treated nonoperatively.
