Cerebral abscesses after endovascular coiling of a paraophthalmic aneurysm: Case report and review of the literature.

Background: Intracranial infections are a rare complication of therapeutic neuroendovascular procedures.

Case Description: We present a case of a 72-year-old female with multiple unilateral cerebral hemisphere abscesses after endovascular embolization of a right paraophthalmic aneurysm and also provide a comprehensive review of the literature on cerebral abscesses following neurovascular embolization.

Conclusion: Infection following coil embolization of cerebral aneurysm is rare. However, it is likely to increase in the setting of increased used of neuroendovascular techniques in the future. Therefore, we suggest that extreme care is taken to ensure proper asepsis during embolization, and a high index of suspicion is maintained in patients with predisposing characteristics (large hemorrhage, ischemia, recurrent endovascular procedures, right-to-left shunt, and concomitant infection). Given the fact that the majority of abscesses occurred in patients who have had ruptured aneurysms, we suggest consideration is given to prophylactic intraprocedural intravenous antibiotics use as seen with open aneurysm treatment.
