Management of infected caval filter with simultaneous aortic pseudoaneurysm and retroperitoneal perforation: a case report and literature review

Abstract

Inferior vena cava (IVC) filters have been reported to have complication rates up to 35%. Penetration of surrounding retroperitoneal structures is an uncommon, but potentially serious, complication, with several reports in the literature. We present a unique case of a 34-year-old intravenous drug user with infected IVC filter struts penetrating multiple structures simultaneously. Definitive operative management was necessary for removal of filter struts from the aorta, the second part of the duodenum and the iliopsoas muscle. Drainage and debridement of an associated iliopsoas abscess was performed, followed by aortic and caval reconstruction.
