Large and bleeding gastroduodenal artery aneurysm: Challenging diagnosis and treatment. A case report.

Visceral artery aneurysms (VAA), including gastroduodenal artery aneurysms (GAA), are rare pathologies that can be challenging to diagnose due to their often-asymptomatic nature. VAA are usually correlated to atherosclerosis, fibro dysplasia, or hemodynamics changes, while pseudo aneurysms are mostly correlated to infection, inflammation, traumas, or iatrogenic lesions. We report the case of an 82-years-old female presenting with abdominal pain and hematemesis. Upper gastrointestinal endoscopy retrieved a large duodenal mass and subsequent CT scans identified a large GAA with contrast extravasation. Endovascular procedure included selective arteriography, microcatheterization, and embolization. VAA are mostly located in the splenic and hepatic artery. Symptoms of VAA are related to pressure on neighboring organs. VAA rupture is associated with a high mortality risk (over 76 %) and presents with symptoms like acute abdominal pain, hematemesis, and hemodynamic shock. Diagnosis is often made through CT scans and angiography. Treatment options for VAAs and GAAs include both surgical and endovascular methods. Endovascular treatment is preferred, with a success rate of 89 %-98 %. This case provides an example of challenging diagnosis and treatment of a large and bleeding GAA.
