Aneurysm of the inferior mesenteric artery associated with occlusion of the celiac axis and superior mesenteric artery.
The authors report a case of aneurysm of the inferior mesenteric artery encountered in a 38-year-old man, associated with occlusion of the celiac axis, the superior mesenteric artery and the inferior mesenteric artery distal to the aneurysm. All three arteries were revascularized. In spite of failure in the bypass of the superior mesenteric artery, the patient remained symptom free until his demise four years later, from a probable myocardial infarction. Only 11 cases of aneurysms of the inferior mesenteric artery have been reported in the literature. The causes, diagnosis and treatment of these uncommon lesions are discussed. When occlusion of the celiac axis is associated with that of the superior mesenteric artery, a complete mesenteric revascularization should be attempted whenever possible.
