Aneurysms of the duodenopancreatic arcades: diagnostic imaging and therapeutic indications: 2 case reports

BACKGROUND: Aneurysms of the duodenopancreatic arcades account for 2 to 3% of all aneurysms of the digestive arteries. Mortality is high due to the ri sk of rupture and the difficult diagnostic situation. CASE REPORTS: The first case involved a short wide collar aneurysm implante d on the first centimeter of the superior mesenteric artery, associated wit h tight stenosis of the celiac trunk. The patient complained of diffuse abd ominal pain and was treated surgically. In the second case, there was a fal se aneurysm of the gastroduodenal artery which developed a few months after acute biliary pancreatitis. The aneurysm was treated by exclusion using a transcutaneously delivered endovascular coil prosthesis. CONCLUSION: These cases illustrate the importance of imaging (magnetic reso nance angiography) both for diagnosis and treatment monitoring, allowing ea rly care with very limited morbidity and mortality.
