Preoperative embolization of intracranial meningiomas

Neurosurgery. 1983 Sep;13(3):261-8. doi: 10.1227/00006123-198309000-00008.


The operative and histopathological findings in 31 cases of intracranial meningioma after preoperative embolization with Gelfoam and/or lyophilized dura mater are reported. Removal of the tumor after embolization was facilitated in those meningiomas fed exclusively or mainly by branches of the external carotid artery (29 of 31). Large areas of tumor necrosis were never seen on histopathological examination, even when suggested by large regions of decreased density on the postembolization computed tomographic scan. Preoperative embolization of the feeding vessels arising from the external carotid artery system has proven to be a useful adjunct before the resection of intracranial meningiomas.
