Mycotic Celiac Artery Aneurysm

Mycotic celiac artery aneurysm (MCAA) is extremely rare. To date, only 8 cases have been reported in the literature. Endocarditis is the most commonly documented etiology. Here, we report a case of a subacute, symptomatic MCAA presenting with progressive enlargement in a patient who was previously treated for bacterial endocarditis. Management involved a 2-stage surgical intervention: First, aortohepatic bypass with autologous conduit via transperitoneal approach, followed several days later by ligation of the aneurysm base via retroperitoneal exposure. The treatment options for this rare pathology are also discussed along with a literature review.
