“…The SMA aneurysm ruptured during hospitalization even though the patient received 6-week antibiotic therapy. To our knowledge, there are four similar cases in which SMA aneurysm was a complication of IE, with it rupturing after 2 weeks [Zhao 2008;Chu 2005], 4 weeks [Silver 1999], or 6 weeks [Buchs 2013] of antibiotic treatment. It seems that antibiotic treatment could not prevent the rupture of SMA mycotic aneurysm.…”

Mycotic aneurysm of the superior mesenteric artery (SMA) is a rare complication of infective endocarditis. We report a case with infective endocarditis involving the aortic valve complicated by multiple septic embolisms. The patient was treated with antibiotics for 6 weeks. During preparation for surgical treatment, the patient developed acute abdominal pain and was diagnosed with a ruptured SMA aneurysm, which was successfully treated with an emergency operation of aneurysm ligation. The aortic valve was replaced 17 days later and the patient recovered uneventfully. In conclusion, we present a rare case with infective endocarditis (IE) complicated by SMA aneurysm. Antibiotic treatment did not prevent the rupture of SMA aneurysm. Abdominal pain in a patient with a recent history of IE should be excluded with ruptured aneurysm.

“…The number of SMA aneurysms discovered incidentally, with the utilization of cross-sectional imaging, has risen from 10% to 50% in some studies [4,6,[9][10][11]. Reported size for main SMA trunk aneurysms varies from 2 to 9 cm, with side branch aneurysms usually less than 1 cm [12,13]. Historically, infection has been the major etiology of SMA aneurysms, accounting for 31 to 63% of them [13,14].…”

“…The typical approach is trans-peritoneal. Given well-developed collateral flow, resection without reconstruction usually suffices [6,12] and branch aneurysms can frequently be treated with simple ligation. Per and post-operative vigilance for proof of intestinal ischemia is mandatory, and reconstruction is more likely to be necessary for proximal main trunk aneurysms [3,8].…”

Background: Aneurysms of the superior mesenteric artery (SMA) and its branches are uncommon complication of infective endocarditis (IE) and have a high rate of rupture and mortality. Case Report: A 50-year-old female was diagnosed and treated for IE with good initial evolution. During pre-surgery evaluation, the patient developed hemorrhagic shock. Computed tomography angiogram revealed hemoperitoneum and contrast extravasations due to rupture of aneurysm originating from an SMA's branch. The patient was transferred for urgent surgery. On laparotomy large, inflamed, pulsatile mesenteric mass with free blood in the pelvis was found. Evidence of necrotic small bowel was detected and resection of 25 cm with ileostomy was performed and surgery for restoring bowel continuity after ileostomy was programmed three months later with good results. Conclusion: Although main trunk and superior mesenteric artery (SMA) branch aneurysms account for only 5.5% of all visceral artery aneurysms, early identification and expedient management are very important given an associated 38-50% rupture rate and 30% mortality.

“…7 In contrast to nonmycotic aneurysms (atherosclerosis, dysplasia, arteritis, collagen disorders, and trauma), mycotic aneurysms usually occur in young patients (<50 years of age). 3,8,9 Nonmycotic aneurysms typically affect patients after the sixth decade of life. 4 Most mycotic aneurysms now arise from hematogenous seeding of the vessel wall, mechanical injury, collagen vascular disorders, or secondary infection of existing aneurysms.…”

Superior mesenteric artery (SMA) aneurysm is the third most common splanchnic artery aneurysm. A 73-year-old woman presented with a minimally symptomatic SMA aneurysm, which was resected by laparoscopic surgical technique. The patient recovered quickly and remained well after 8 months of follow-up. This case report and literature review presents a rare mycotic aneurysm that developed in the SMA. Laparoscopic surgery can be a useful technique for the treatment of mycotic SMA aneurysms.
