Balloon-assisted embolization of skull base meningioma with liquid embolic agent

Technical note

Restricted access

The authors report a novel technique of balloon-assisted embolization of a skull base meningioma supplied by a branch of the cavernous segment of the internal carotid artery using liquid embolic agent. A temporarily inflated balloon distal to the meningioma's feeding vessel may improve the access to this small branch and may reduce the chances of unintended reflux during delivery of the liquid embolic agent.

Abbreviations used in this paper: ICA = internal carotid artery; ILT = inferolateral trunk.

    A: Coronal T2-weighted MR image showing a large left anterior clinoid meningioma, encasing the terminal portion of ICA (arrow). B: Lateral view angiogram obtained in midarterial phase after left ICA injection showing dilated ILT (arrow) and the blush of the meningioma. C: Right oblique view 3D angiogram demonstrating the inferiorly directed origin of the dilated ILT (arrow). D: Road map image in the working projection, similar to Fig. C, showing the temporarily inflated balloon distal to the origin of the ILT. Note the tip of the microcatheter (arrow) within the ILT. E: Lateral view angiogram obtained in midarterial phase after left ICA injection confirming near-complete disappearance of the blush of the meningioma.
