Delayed post-traumatic left gastric artery pseudoaneurysm presenting with massive upper gastrointestinal hemorrhage: a case report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction and importance: Post-traumatic visceral artery pseudoaneurysms are rare vascular entities but carry a high risk of catastrophic hemorrhage. They most commonly involve the hepatic artery, while pseudoaneurysms of the left gastric artery are exceptionally uncommon. Delayed presentation several years after trauma is particularly rare and poses significant diagnostic challenges. Presentation of case: We report the case of a 37-year-old woman who presented with massive hematemesis and hemodynamic instability. She had a history of childhood abdominal trauma following a road traffic accident requiring partial splenectomy and reported vague abdominal pain in the weeks preceding the event. Initial differential diagnoses included peptic ulcer bleeding and esophageal varices. Upper gastrointestinal endoscopy revealed a large amount of intragastric blood without an identifiable source. Contrast-enhanced CT angiography demonstrated a saccular pseudoaneurysm of the left gastric artery with tortuous vessels. During preparation for endovascular embolization, the patient developed recurrent massive hemorrhage requiring emergency laparotomy. Intraoperative findings confirmed rupture into the gastric lumen, and hemostasis was achieved by ligation of the left gastric artery. The postoperative course was uneventful, and the patient was discharged in stable condition. Clinical discussion: Visceral artery pseudoaneurysms should be considered in unexplained gastrointestinal bleeding, particularly in patients with prior abdominal trauma. CT angiography is essential for diagnosis and guides management. Endovascular embolization is preferred in stable patients, whereas active rupture requires urgent surgical intervention. Conclusion: Delayed post-traumatic pseudoaneurysms should be included in the differential diagnosis of severe gastrointestinal hemorrhage. Early recognition, prompt imaging, and timely intervention are crucial to improve outcomes.
