Mycotic aneurysm of superior mesenteric artery caused by Candida albicans in a patient with chronic aortic dissection: The utility of in situ right gastroepiploic artery

Mycotic aneurysm of the superior mesenteric artery is a rare condition in the literature. Here, we present a case of mycotic aneurysm of the superior mesenteric artery induced by <i>Candida albicans</i>, for which we successfully performed an aneurysmectomy and in situ gastroepiploic artery bypass in a 60-year-old patient with chronic aortic dissection. Postoperative three-dimensional computed tomography angiography revealed the patency of the in situ gastroepiploic artery. Pathology verified the presence of <i>Candida albicans</i> in the aneurysmal wall. In situ gastroepiploic artery restored the antegrade blood supply to the superior mesenteric artery. In addition, use of in situ gastroepiploic artery does not need arterial inflow.
