Reconstruction with a Bovine Pericardial Patch of Infected Juxtarenal Aortic Aneurysm

An infected aortic aneurysm (IAA) is a rare and fatal disease. Especially, it is challenging to repair IAA at the level of the renal artery. A 76-year-old male was referred to our hospital because of low grade fever, a flank pain, and lumbago for 1-month duration. The infected and juxtarenalsaccular formed aortic aneurysm was diagnosed by biochemistry examinations and computed tomography angiogram. We started intravenous antibiotic treatment. A patch repair of the aneurysmal neck using a bovine pericardial patch was performed under renal hypothermia. Long-term antibiotic therapy was given postoperatively. No signs of recurrent infection and aneurysmal dilatation of the aorta were observed for 5 years after surgery. Bovine pericardial patch plasty could be one of the surgical options for IAA, especially in patients with severe adhesion to the aneurysm.
