Preoperative onyx embolization of meningiomas fed by the ophthalmic artery: a case series.
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.
متن کاملPreoperative embolization of intracranial meningiomas.
The goal of preoperative embolization of intracranial meningiomas is to facilitate their surgical removal by reducing tumor vascularity and decreasing blood loss during surgery. This study is based on personal experience with about 100 embolized meningiomas and on the experience of others. Embolization is performed during the same session as diagnostic angiography. The appropriate embolic mater...
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 کاملPreoperative Onyx embolization of aggressive vertebral hemangiomas.
We report the first use of Onyx in the embolization of spinal tumors in 2 cases of aggressive vertebral hemangioma. In both cases, Onyx embolization provided effective preoperative tumor devascularization after the initial prolonged particulate embolization with Embospheres made little overall impact. Onyx enables a more rapid and visible embolization than particles and is less technically dema...
متن کاملshort term outcomes of gamma knife radiosurgery for skull base meningiomas in iran
introduction: skull base meningiomas constitute a large proportion of the meningiomas, which are the most common benign brain tumors. the treatment of skull base meningiomas is specially challenging and controversial due to the proximity of these tumors to the vital brain structures. radiosurgery is now emerging as an efficient alternative treatment modality which involves the ablation of tumor...
