Prosthetic stent graft infection after endovascular abdominal aortic aneurysm repair

Kaplan-Meier life table analysis demonstrates freedom from graft-related sepsis. The number of patients at risk for each interval time is shown.

Labelled white cell scan shows area of increased uptake in the distal part of the stent graft (arrowhead).

Computed tomography scan shows (arrowhead a) the left limb of the aortobiiliac device and (arrowhead b) a large area of low density anterior to left psoas muscle and adjacent to the left limb of the graft with peripheral enhancement suggestive of acute abscess.

Intraoperative picture shows (arrowhead a) aneurysm sac opened up with pus aspirated from the sac, (arrowhead b) stent graft inside the sac, and (arrowhead c) a back-bleeding lumbar artery controlled with a suture.

Computed tomography scan shows (arrowhead a) marked thickening of the aortic wall, (arrowhead b) adjacent lymphadenopathy, and (arrowhead c) stranding of the surrounding fat planes suggestive of intense inflammatory response.
