Infected Paravisceral Aneurysm Repair with Parallel Stent Grafts

An infected aortic aneurysm (IAA) is a rare but potentially life-threatening pathology characterized by rapid growth and a substantial risk of rupture compared to non-infected aneurysms. Reports on the endovscular treatment of infected paravisceral aneurysms are limited in the literature. This article describes our experience with endovascular repair of IAAs involving the visceral arteries and includes a literature review. We present two cases of symptomatic IAAs located at the celiac trunk ostium in high-risk surgical patients. Both cases were successfully treated with the parallel stent grafting (PG) technique in combination with prolonged antibiotic therapy. A bibliographic review of the endovascular treatment of IAAs was also conducted. Complex endovascular repair of paravisceral IAAs using a combination of a thoracic aortic stent graft and PG, together with prolonged antibiotic therapy, appears to be a reasonable treatment option with promising short- and medium-term results.
