Endovascular therapy for aneurysmal dilatation and arteriovenous fistula of the superior mesenteric artery.

ObjectivesWe present a clinical case illustrating the feasibility of endovascular treatment of superior mesenteric aneurysm associated with an arteriovenous fistula.MethodsThe patient presented with abdominal pain and diarrhea on admission. Computed tomography angiography revealed an aneurysmal dilatation of the superior mesenteric artery and vein with an arteriovenous fistula. Endovascular therapy successfully managed the condition by reconstructing the artery, closing the fistula, and occluding the aneurysm.ResultsNo aneurysm rupture or endoleak occurred, and the patient's symptoms on admission resolved.ConclusionsEndovascular treatment is a viable alternative for patients with superior mesenteric aneurysms and arteriovenous fistulas, but larger studies and further follow-up are needed to evaluate the safety and long-term efficacy of endovascular treatment.
