Background: An infected aortic aneurysm (IAA) is a rare and life-threatening disease. The aim of this study is to elucidate mid-term outcomes of IAA, incorporating patch angioplasty with bovine pericardium. Materials and Methods: Between June 2011 and August 2020, eight patients (one woman, seven men) with infected aneurysms of the thoracic and abdominal aorta were treated surgically. Results: There was no surgical/hospital death. There were two late deaths at follow-up. One patient (patient 6) was re-admitted to the hospital with vomiting blood four months after surgery and died despite treatment. Another patient (patient 5) died at his home 12 months after surgery, and the cause of death was unknown. Six patients remained alive with no evidence of recurrent aneurysm formation due to infection at a mean follow-up of 70.3 (range, 13-110) months. Conclusions: BPPA could be one of the surgical options for IAA, especially in patients with severe adhesion around the aneurysm.
