Mechanical Embolectomy of Distally Migrated Onyx After Surgical Resection of Glomus Vagale Tumor: Technical Report and Review of Literature

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.
