Abstract
Objective: This is a case report of delayed distal coil migration after coil embolization of the ruptured cerebral aneurysm.
Case presentation: A 68-year-old man became unconscious suddenly and was transferred to our hospital. Glasgow Coma Scale (GCS) score was E1V1M5. Head CT revealed subarachnoid hemorrhage (SAH). Digital subtraction angiography (DSA) revealed an anterior communicating artery (Acom) aneurysm. Endovascular coiling of the Acom aneurysm was performed to prevent re-bleeding. under general anesthesia. Acute cardiac infarction developed on day 16, and the patient was treated in the cardiovascular department. Follow-up CT on day 38 revealed a high-density sign at the distal part of the anterior cerebral artery. No further treatment was performed since the patient was asymptomatic.
Conclusions: Delayed distal coil migration may occur after coil embolization of cerebral aneurysm. X-ray examinations (CT and craniogram) were helpful for diagnosis of delayed distal coil migration after endovascular treatment of cerebral aneurysm.
