Persistent iliac endarteritis with pseudoaneurysm formation following balloon-expandable stent placement

We present a patient who developed endarteritis and pseudoaneurysm formation complicating iliac artery stent placement. Blood cultures grew Staphylococcus aureus. Three weeks after antibiotic treatment, the aortic bifurcation and the stents were removed, together with the left common iliac artery pseudoaneurysm. As with any other implantable device, septic complications are dreaded and should be recognized and treated early. Consideration may be given to the use of appropriate prophylactic antibiotics.
