Preservation of Multiple Infected Prosthetic Grafts by Computed Tomography-guided Drainage: A Case Report

Abstract

A 76-year-old man who had undergone open graft replacement for a ruptured abdominal aortic aneurysm. The abdominal aorta on the central side of the artificial vessel replacement became aneurysm, the patient underwent stent graft insertion with abdominal debranching. On postoperative day 78, a Computed Tomography (CT) showed an abscess cavity, which was diagnosed as graft infection. We decided that re-open graft replacement and peripheral revascularization and open drainage would be difficult to tolerate due to the invasive of the surgery and his general condition. CT-guided puncture was performed in the supine position, and a catheter was placed in the abdominal aortic aneurysm contiguous with the abscess cavity, followed by open drainage, saline flushing, and local and systemic administration of antibiotics. Fever and inflammatory reaction improved, and the patient continued to have no recurrence after removal of the catheter, and was discharged.
