# A Novel, Combined Endoscopic Technique to Reveal a Gastric Ulcer Underlying a Left Gastric Artery Pseudoaneurysm

## TL;DR

A rare case of a left gastric artery pseudoaneurysm caused by a gastric ulcer is successfully treated using a new endoscopic method.

## Contribution

A novel combined endoscopic technique is introduced for diagnosing and managing a rare left gastric artery pseudoaneurysm.

## Key findings

- The patient was hemodynamically unstable with a significant clot burden.
- The novel approach revealed a gastric ulcer underlying the pseudoaneurysm.
- The treatment was successful in managing the pseudoaneurysm and preventing fatal bleeding.

## Abstract

Pseudoaneurysms, or false aneurysms, result from an arterial wall tear and can arise from trauma, infection, or inflammation. Common types include aortic, cardiac, and femoral pseudoaneurysms, while left gastric artery pseudoaneurysms (LGAP) are rare visceral occurrences, with only a handful of documented cases. LGAPs are often associated with recurrent pancreatitis and require prompt recognition and treatment due to their high risk of rapid bleeding and fatal outcomes if left untreated. We present a case of a hemodynamically unstable patient with a significant clot burden, successfully managed with a novel approach that revealed an LGAP with a penetrating gastric ulcer at the pseudoaneurysm site.
