Key result
An elderly man with an asymptomatic abdominal aortic aneurysm developed small bowel obstruction due to duodenal compression (aortoduodenal syndrome) and was managed non-operatively.
Case Report (n=1)
Highlights the importance of considering indolent complications of enlarging abdominal aneurysms, such as aortoduodenal syndrome, in an ageing population.
Clinicians should consider aortoduodenal syndrome in frail AAA patients with obstruction; this Level 5 case leaves optimal management open.
An elderly man presented to the emergency department with symptoms suggestive of small bowel obstruction. His medical history included an asymptomatic abdominal aortic aneurysm. Investigations confirmed small bowel obstruction, caused by the aneurysm compressing his duodenum: a condition known as 'aortoduodenal syndrome'. Due to the patient's age, frailty and preference, he was managed non-operatively. The case highlights the importance of considering indolent complications of enlarging abdominal aneurysms in an ageing population.

Niklewicz et al. (2025) conducted a case report in Aortoduodenal syndrome (n=1). Non-operative management was evaluated. An elderly man with an asymptomatic abdominal aortic aneurysm developed small bowel obstruction due to duodenal compression (aortoduodenal syndrome) and was managed non-operatively.
