چکیده
We report the feasibility and efficacy of percutaneous injection of Onyx (Micro Therapeutics, Irvine, Calif.), a nonadhesive liquid embolic agent, into an unusually located paraganglioma, followed by endovascular embolization with particles before surgery.

Comment on: Current concepts in the management of carotid body tumours.
Preoperative embolization has played a major role in the devascularization of carotid body tumours prior to surgery. There are two currently approved methods to achieve this, which is a superselective transarterial endovascular embolization and a direct percutaneous injection of embolic materials . Superselective transarterial endovascular embolization has potential limitations especially in le...
متن کاملPercutaneous embolization of carotid paragangliomas using solely Onyx.
BACKGROUND AND PURPOSE Paragangliomas are highly vascularized usually benign neoplasms arising from nerve tissue. Endovascular preoperative embolization is used to facilitate surgery but is often not complete, due to tiny feeding arteries not feasible for selective catheterization. Our purpose was to evaluate angiographic and clinical outcome using Onyx for percutaneous glomus tumor embolizatio...
متن کاملUsefulness of percutaneously injected ethylene-vinyl alcohol copolymer in conjunction with standard endovascular embolization techniques for preoperative devascularization of hypervascular head and neck tumors: technique, initial experience, and correlation with surgical observations.
BACKGROUND AND PURPOSE Few reports have described the embolization of head and neck lesions by using direct percutaneous techniques. We report our preliminary experience in the direct percutaneous embolization of hypervascular head and neck tumors by using Onyx in conjunction with standard endovascular embolization techniques. We describe the technical aspects of the procedure and its efficacy ...
متن کاملPreliminary experience with the percutaneous embolization of juvenile angiofibromas using only ethylene-vinyl alcohol copolymer (Onyx) for preoperative devascularization prior to surgical resection.
BACKGROUND AND PURPOSE Juvenile angiofibromas are hypervascular tumors that may benefit from preoperative devascularization to reduce intraoperative blood loss. Our purpose was to evaluate the extent of angiographic devascularization and intraoperative blood loss by using only Onyx for percutaneous juvenile angiofibroma tumor embolization. MATERIALS AND METHODS We reviewed the clinical record...
متن کاملCombined preoperative onyx embolization and protective internal carotid artery covered stent placement for treatment of glomus vagale tumor: review of literature and illustrative case.
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 tomography angiography showed an encased internal carotid artery. Cerebral angiography demonstrated a highly vascular tumor....
