Degenerative aneurysms of the SFA display peculiar characteristics (in terms of clinical onset, diagnostic timing, and clinical behavior) so that they differ from other peripheral aneurysms. In fact, they often grow to reach a considerable diameter before medical attention is sought, presenting with rupture or ischemia at diagnosis. SFA aneurysms preferentially affect elderly men and are often associated with aneurysms elsewhere. However, despite their rarity, the treatment is usually feasible, and long-term outcomes are good.

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.
