[Case study of ruptured gastroduodenal artery aneurysm revealed by hematemesis]. / Anévrisme rompu de l'artère gastroduodénale révélé par des hématémèses: à propos d'un cas.

Gastroduodenal artery aneurysm is a rare vascular lesion, asymptomatic in the majority of cases. However, ruptured aneurysm is associated with poor prognosis and mortality can achieve a 40% rate. We here report the case of an 83-year-old patient with abrupt onset of non-specific abdominal pain associated with hematemesis. Endoscopy showed beating formation compressing the duodenal bulb with active bleeding. Abdominal computed tomography (CT) scan was performed which objectified gastro duodenal artery aneurysms involving the artery ostium and making endovascular treatment impossible to perform. Thus, the patient underwent open surgery based on flattening associated with aneurysm exclusion and then complemented by bulb plasty. Post-operative CT scan confirmed total exclusion of the aneurysm with preservation of hepatic circulation.
