Conservative treatment of left gastric artery pseudoaneurysm caused by a gastric ulcer

Abstract

A 71-year-old man was admitted to our hospital because of dehydration, rhabdomyolysis, decubitus ulcers, and severe dementia. The patient, who suddenly passed black tarry stools and had a drop in the hemoglobin level on the third day of hospitalization, underwent emergency upper endoscopy that revealed an ulcer without an exposed vessel at the gastric angle. The patient received blood transfusions and proton pump inhibitors (PPI) . The upper endoscopy after 2 weeks showed a pseudoaneurysm measuring approximately 10 mm at the ulcer floor. CT angiography indicated left gastric artery pseudoaneurysm. In consideration of the fact that the patients had dementia and poor performance status, conservative treatment continued. After 1 month, an endoscopy revealed that the aneurysm was tending toward a decrease in size, and after 2 months, it revealed the disappearance of the aneurysm. Here, we report a rare case of pseudoaneurysm.
