The diagnostic value of digital subtraction angiography of intracranial meningioma / 介入放射学杂志

ABSTRACT

Objective To evaluate the diagnostic value of digital subtraction angiography (DSA) of intracranial meningioma.Methods DSA was performed in 115 cases with meningioma. The branches of the external carotid artery were embolized in 76 cases. Results The blood supply of the meningioma located at the relatively superficial cerebrum are mainly arising from the middle meningeal artery of the internal maxillary artery and those located at the skull base are mainly from the ophthalmic artery and the cerebral segment of the internal carotid artery. The possible dangerous anastomoses between the extermal and internal carotid arteries and the vertebrobasilar arteries may exist.Conclusions To have a good knowledge of the charactereristics of digital subtraction angiography of meningioma is crucial for endovascular embolization and operation of meningioma.
