Simultaneous Valve Replacement and Venous Patch Repair of Superior Mesenteric Artery Aneurysm Due to Infective Endocarditis: A Case Report
Background. Peripheral mycotic aneurysm development is a rare systemic complication of infective endocarditis.
Case report. We report on a case of a mycotic aneurysm of the superior mesenteric artery in a 66-year-old man with infective endocarditis of the mitral valve. After the mitral valve was replaced by a mechanical valve, a laparotomy was performed. The mycotic aneurysm was excised and the vessel was repaired by sewing an autologous venous patch at the neck of the aneurysm. Five years after the operation, the patient is doing fine, with a normal morphology and patency of the superior mesenteric artery.
Conclusion. Our case demonstrates that simultaneous valve surgery and repair of a superior mesenteric artery mycotic aneurysm by sewing a vein patch in the neck of the artery is a viable treatment option.
