A minimally invasive approach to the infected aorta with novel endovascular use of biocomposite antibiotic material.

We have presented the case of a symptomatic, primarily infected aortic pseudoaneurysm treated with endovascular stent graft exclusion and adjunctive use of a long-acting biocomposite antibiotic material injected directly into the pseudoaneurysm sac. We have described preparation of the biocomposite antibiotic material and the catheter-directed delivery technique in detail. Although the use of long-acting antibiotic materials such as antibiotic beads has been well described when performing open surgery in an infected field, the application of these materials in endovascular procedures has been less certain.
