Mycotic aneurysm of the inferior pancreaticoduodenal artery: successful nonoperative management.

Although mycotic aneurysms of small visceral arteries are rare, they have a high morbidity and mortality due to rupture and sepsis. Any patient with abdominal pain and bacterial endocarditis should be suspected of having a mycotic aneurysm. Selective arteriography confirms the diagnosis. In the case we have reported, diagnosis of a mycotic aneurysm of the inferior pancreaticoduodenal artery was established by angiography, and the patient was treated by percutaneous transcatheter embolization. This case demonstrates that mycotic aneurysms of small visceral arteries may be managed nonoperatively with antibiotics and percutaneous transcatheter embolization therapy.
