# Large gastroduodenal artery pseudoaneurysm presenting as gastric outlet obstruction: a case report

## TL;DR

A rare case of a large gastroduodenal artery pseudoaneurysm causing gastric outlet obstruction is reported, highlighting the importance of considering vascular anomalies during endoscopic investigations.

## Contribution

This case report presents a rare presentation of a gastroduodenal artery pseudoaneurysm as gastric outlet obstruction.

## Key findings

- GDA pseudoaneurysm can present as gastric outlet obstruction, a rare and atypical symptom.
- Endoscopic investigation should consider vascular anomalies as a potential cause of gastric outlet obstruction.
- Timely diagnosis and management of such pseudoaneurysms are critical to prevent life-threatening complications.

## Abstract

Visceral artery aneurysms are a rare and potentially lethal clinical presentation. They can be asymptomatic or present with large volume gastrointestinal bleeding. Gastric outlet obstruction is a rare clinical presentation for a visceral artery aneurysm. We present a case of a GDA pseudoaneurysm presenting as gastric outlet obstruction and the diagnosis and management of the case. It is important to keep vascular anomalies in mind, particularly when performing endoscopic investigation.
