Preoperative onyx embolization of meningiomas fed by the ophthalmic artery: a case series.

چکیده
Embolization of head and neck hypervascular tumors is a well-established therapeutic technique. Preoperative embolization reduces intraoperative blood loss, shortens the length of surgery, and decreases surgical morbility and mortality. This study assesses the safety and efficacy of preoperative embolization of meningiomas fed by the OPH by using Onyx liquid embolic agent.

Preoperative Embolization of Extra-axial Hypervascular Tumors with Onyx
OBJECTIVE Preoperative endovascular embolization of intracranial tumors is performed to mitigate anticipated intraoperative blood loss. Although the usage of a wide array of embolic agents, particularly polyvinyl alcohol (PVA), has been described for a variety of tumors, literature detailing the efficacy, safety and complication rates for the usage of Onyx is relatively sparse. MATERIALS AND ...
متن کاملOnyx Embolization of a Meningioma with a Dysplastic Aneurysmal Anterior Cerebral Artery Vessel
Preoperative embolization of meningiomas can be safely performed using a variety of embolic agents. Most commonly, the vascular supply from branches of the external carotid artery is the target of embolization. In our report, we detail the treatment of a patient with a parafalcine meningioma that received its supply via branches of the anterior cerebral artery. One of the feeder vessels appeare...
متن کامل[Preoperative embolization of intracranial meningiomas].
The method and results for preoperative embolization are described in 36 cases with intracranial meningiomas. Embolization materials were injected through a transfemoral catheter, selectively placed in the external carotid artery. Chopped gelfoam served as embolization material in 29 pa tients and ivalon particles were used in 7 patients. In 19 out of 36 cases the feeding arteries arose ...
متن کاملComment 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...
