Percutaneous transluminal angioplasty and endovascular stent placement are becoming common techniques for iliac artery stenosis and obstruction that are intended to reduce the need for surgical bypass procedures. The usual complications include acute or subacute thrombosis, distal embolization, dissection, and extravasation. Although stent infection is very rare after stent replacement, it is reportedly associated with a high risk of morbidity and mortality, and the use of prophylactic antibiotics should be considered. We present a case of rupture of an infected pseudoaneurysm at the site of the external iliac artery that occurred 4 months after an uneventful percutaneous transluminal angioplasty and stent placement.
