Pelvic abscess following internal iliac artery embolization prior to endovascular aneurysm repair.

We describe a previously unreported case of abscess formation around the right internal iliac artery (IIA) after coil embolization prior to endovascular aneurysm repair (EVAR). A 75-year-old man was admitted for elective repair of a right common iliac aneurysm. The right IIA coil embolization and EVAR procedures were uncomplicated and assessment by postoperative computed tomography (CT) was satisfactory. The patient was readmitted 2 weeks after EVAR with right buttock pain and pyrexia. CT indicated an isolated abscess around the coil-embolized IIA. The patient was successfully treated with CT-guided percutaneous drainage.
