Antibiotics and Drainage for Treating Stent-Graft Infection after EVAR

Abstract

The patient was a 64-year-old man. He developed fever and lumbago 6 months after the EVAR. Because CT showed an abscess in the aortic aneurysm surrounding the stent graft, stent-graft infection was diagnosed, and treatment with intravenous antibiotics was initiated. However, the fever and inflammatory markers persisted; therefore, CT-guided drainage catheter placement was performed. After all the pus had been discharged, the fever subsided, and the inflammatory reaction was also suppressed. One year has elapsed since the treatment, and the patient continues to visit with no complaints. We report that stent-graft infection was relieved with antibiotics and drainage.
