Management of endograft infections

Abstract

Endovascular abdominal aortic aneurysm repair (EVAR) and thoracic endovascular aneurysm repair (TEVAR) have become well-accepted alternatives to traditional open surgery because of the diminished perioperative complications. Aortic stent-graft infection is an uncommon complication and little is known about the general features of and potential risk factors for aortic stent-graft infection, and treatment is administered on a case-by-case basis with no consensus guidelines. Despite a low infection rate, the associated mortality rates are extremely high and the morbidity rate, even with aggressive surgical interventions, is also high. Since 1991 only 117 cases of thoracic and abdominal endograft infections have been reported in the literature. This paper presents a detailed analysis of the features of all cases reported to date and reviews the epidemiology, diagnosis, management, and outcomes of thoracic and abdominal endograft infections.
