Ligature and Removal of Mesenteric Artery Aneurysm Associated to Resection of the Terminal Ileum in Patient with Endocarditis and Negative Blood Cultures

Abstract

The term mycotic aneurysm involves an infection of secondary aneurysmal wall to bacterial endocarditis. The 63% of mycotic aneurysms of the superior mesenteric artery are due to embolism from a septic endocarditis. Although most of these aneurysms is diagnosed, due to the increase in diagnostic methods, even a quarter of the superior mesenteric artery aneurysms present with rupture, intestinal ischemia and hemodynamic instability by increasing the mortality and morbidity of this disease. We report the case of a patient came to our attention for abdominal pain, suffering from bacterial endocarditis, with diagnosis of the thrombosed superior mesenteric artery aneurysm.
