Gastrointestinal bleeding and mycotic superior mesenteric aneurysm

Abstract

This is a case report of management of a delayed mycotic superior mesenteric artery aneurysm occurring in a patient 2 years after aortic valve replacement for endocarditis. A chronic ulcer history, anticoagulation therapy, episodic gastrointestinal bleeding associated with negative gastrointestinal series, and gastritis seen at endoscopy delayed the ultimate diagnosis. An episode of massive hemorrhage precipitated angiography with subsequent surgical confirmation of the diagnosis. Management included debridement and extirpation of the major part of the aneurysm, Doppler assessment of the inadequacy of collateral mesenteric arterial blood flow, and restoration of flow with a bypassing saphenous vein graft segment. Although this technique of reconstruction has been suggested, we can find no other report of such a similar case among the few reported surgical successes with superior mesenteric artery mycotic aneurysm.
