title: Superior Mesenteric Artery Aneurysm Caused by Aortic Valve Endocarditis: The Case Report and Review of the Literature.
abstract: Infectious aneurysms of the superior mesenteric artery are a rare but life-threatening condition due to the risk of visceral ischemia, sepsis, or hemorrhage. In this study, we report the case of a superior mesenteric artery aneurysm (SMAA) secondary to a bioprosthetic valve endocarditis, successfully managed with aneurysm resection and saphenous vein interposition graft. We performed an extensive PubMed-based rewiew of the literature of the last 10 years on SMAA, which include the detection of 38 articles quoting 41 SMAAs. The case histories were divided in 2 groups: 18 cases belonged to nonmycotic group A and 23 cases were included in mycotic group B. In group A, 44.4% of patients were treated surgically, whereas in group B, 90.5%. The 2 study groups significantly differed (P = .01) in terms of surgical treatment. The surgical approach still remains the first choice of treatment in mycotic aneurysm.
