Preoperative Embolization of Cerebellar Hemangioblastoma with Onyx: Report of Three Cases
نویسندگان
چکیده
Hemangioblastoma is a benign and highly vascular tumor. Complete surgical resection of highly vascular tumor such as hemangioblastoma may be challenging due to excessive bleeding. Preoperative embolization of these lesions may decrease the intraoperative blood loss and facilitate excision. We report three cases of cerebellar hemangioblastomas that were embolized using Onyx.

BACKGROUND The preferred treatment for intracranial hemangioblastomas is surgical resection with or without preoperative embolization, however, embolization remains controversial due to risks such as distal tip entrapment, vascular injury during navigation, and embolic agent migration. CASE DESCRIPTION A 54-year-old woman was admitted for surgical resection and preoperative embolization of a ...

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...

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 ...

A 72-year-old male presented with a primary hemangioblastoma of the posterior fossa with unusual dural attachment and meningeal arterial blood supply from the external carotid artery and marginal tentorial artery. Preoperative embolization facilitated complete resection of the tumor with no resultant neurological deficit. Hemangioblastoma must be included in the differential diagnosis of tumors...
