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.
