A case of thromboembolic complication during coil embolization for unruptured aneurysm successfully treated with additional antithrombotic agent

Abstract

Objective: We report a case of thrombosis as a complication of unruptured aneurysm coil embolization successfully treated by additional use of antithrombotic agent.
Case presentation: An aneurysm of the right basilar-anterior inferior cerebellar artery (AICA) was incidentally revealed in a 66-year-old woman. The aneurysm was successfully embolized using coils, but thrombosis occurred at the AICA. After additional administration of heparin, Clopidogrel, and Ozagrel sodium, the AICA was recanalized. Fortunately, there was no ischemic complication and the patient was discharged without any neurological deficit.
Conclusion: The additional use of anti-thrombotic agents was effective therapy for thromboembolic complications of unruptured aneurysm coil embolization.
