Abstract: Objective: Surgical resection of complex glomus vagale tumors can be complicated by extensive blood loss and might require surgical sacrifice of an encased internal carotid artery. Methods: A young patient presented with mass effect from glomus valage tumor. Computerized tomorgraphy angiography showed an encased internal carotid artery. Cerebral angiography demonstrated a highly vascular tumor. A literature review was performed for endovascular treatment options for neck tumors. Results: Staged preoperative embolization of feeder arteries via internal maxillary artery, and thyrocervical trunk with Onyx was performed. A covered stent was implanted in the cervical internal carotid artery to the common carotid artery; this resulted in complete devascularization of the tumor with exclusion of external carotid artery from the circulation. This is followed by surgical resection of the tumor. Conclusion: Preoperative embolization with Onyx decreased the amount of blood loss intra-operatively. The implantation of a covered stent in the cervical internal carotid artery through the common carotid artery contributed for further devasculatization of the tumor bed, as well as provided a lumen continuity in case iatrogenic carotid injury is encountered intra-operatively
