Abstract:
An inferior mesenteric artery (IMA) aneurysm is the rarest among visceral artery aneurysms. A 69-year-old man was referred to our hospital with an asymptomatic IMA aneurysm associated with occlusion of the superior mesenteric artery (SMA) and celiac artery (CA). After revascularization of the SMA with an 8-mm expanded polytetrafluoroethylene (ePTFE) graft, the aneurysm was resected, and the IMA was reconstructed. The "jet disorder" phenomenon has been thought to cause an IMA aneurysm in the case of CA and SMA obstruction. We consider it better to revascularize not only an IMA but also an SMA or CA for preventing that phenomenon.
