A Rare Cause of Duodenal Obstruction due to Complications of Acute Pancreatitis: A Case Series

Pancreatic pseudoaneurysm is a rare but life-threatening complication of pancreatitis, with varied clinical presentations. We report two cases in which patients presented with duodenal obstruction caused by pseudoaneurysmal rupture. One patient was successfully treated with transarterial embolization, while the other recovered with conservative decompression. These cases suggest the importance of considering pseudoaneurysm as a differential diagnosis in patients with pancreatitis who present with obstructive gastrointestinal symptoms, even in the absence of hemorrhage. Prompt recognition and appropriate intervention are essential to prevent serious outcomes.
