RESUMEN
BACKGROUND: Endovascular embolization is an important tool in the management of multiple pathologies as a preoperative adjunct in the care of arteriovenous malformations or vascular tumors. CASE DESCRIPTION: We report a case of delayed distal Onyx migration after surgical resection of a glomus vagale tumor, which had been preoperatively embolized. In this report, the patient underwent successful embolectomy of the migrated Onyx fragment using manual aspiration. CONCLUSIONS: This case represents the first in the literature to describe this potential delayed complication, as well as its management strategy.

Onyx reflux into the parent artery is a rare and sometimes significant complication in the treatment of cerebral arteriovenous malformations (AVMs). We report a patient who presented with Onyx reflux into the M1 segment of the middle cerebral artery (MCA) during embolization of a right temporal AVM. The refluxed Onyx cast was successfully removed by a mechanical thrombectomy device using a self-expandable and fully retrievable Solitaire AB stent.
