    Abstract:
    BACKGROUND: Left gastric artery (LGA) pseudoaneurysm presenting with upper gastrointestinal (UGI) bleeding is rare but fatal, unless treated. AIMS: We aimed to describe the clinical and endoscopic features of patients with UGI bleeding due to LGA pseudoaneurysms. METHODS: We performed a computerized search of our hospital's de-identified clinical data warehouse to identify patients with UGI bleeding due to an LGA pseudoaneurysm between 2000 and 2020. Patients' electronic medical records and data on esophagogastroduodenoscopy and digital subtraction angiography were reviewed retrospectively. RESULTS: Of 26 patients with an LGA pseudoaneurysm, six patients had UGI bleeding related to an LGA pseudoaneurysm. No patients had previous vascular diseases or pancreatitis. One patient had liver cirrhosis and a history of radiofrequency ablation for hepatocellular carcinoma, one had colon cancer, two had undergone abdominal surgeries, one had received chemoradiotherapy for renal cell carcinoma, and one had no intraabdominal diseases. Symptoms were hematemesis in two, hematochezia in the other two, and melena in the remaining two patients. Esophagogastroduodenoscopy showed a pulsating bulge in the ulcer in two and a large Dieulafoy's lesion-like structure in four patients. All patients achieved hemostasis by angioembolization. CONCLUSION: LGA pseudoaneurysm should be suspected in UGI bleeding if a large Dieulafoy's lesion-like structure or a pulsating bulge in the ulcer is found at the lesser curvature of the gastric body on endoscopy and if the patient has any intra-abdominal inflammatory disease.
